This table contains the full text for all our old WORDPRESS content in html form. The format is a bit odd as it represents a direct copy from wordpress content that includes a lot of wordpress specific comments that carry some meaning in terms of layout instructions etc.. The html in the content column can thus be rendered as is but will not look identical to the way it looks on our website as several post processing steps are not applied yet. The content should work though as a readable approximation for every post. For easy searching etc, a markdown copy of the content is available in the markdown column. If you want to query all posts (both wordpress and gdocs), use the posts_unified table or the posts_unified_with_content view.

Therefore I looked up all the sources for the data he presents.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The topic of Pinker's book is the decline of violence in humanity's history. That would give him an incentive to cherry-pick data that suits his narrative. For this reason I had contact with several of his critics and asked them for their evidence. After this assessment of Pinker's data, I did not find any reason to assume that he cherry-picked. He included all the data that his sources included.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Through my contact with critics of Pinker's book I was referred to a critique of Pinker's data by Douglas Fry.{ref}Fry (2013) - Chapter 1: War, Peace, and Human Nature.

(Middle Missouri) Zimmerman 1980; Wilky 1990; Bamforth 1994; (Southwest) Haas 1990: 187, and personal communication.) For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilaced during an attack on their village a century and a hdf before Columbus's arrival (ca. A.D. 1325). The attack seems to have occurred just when the village's fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village's population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilared in a single attack and never reoccupied.'</li></ul> <!-- /wp:list --> <!-- wp:paragraph --> <p><strong>Site:</strong> Nubia (site 117), 14-12000 years before present <strong>Share of Violent Deaths:</strong> 46%</p> <!-- /wp:paragraph --> <!-- wp:list --> <ul><li><em>My source for the data:</em> Bowles (2009)</li><li><em>Comment and sources:</em> Bowles (2009) quotes F.

(1989) - Population decline in a Philippine Negrito hunter-gatherer Society. American Journal of Human Biology, 1, 59–72.</a></li><li><em>Comment:</em> The source of Pinker on the percentage of deaths in warfare is Bowles (2009) and he made a mistake that Fry (2013) corrects: Bowles (2009) based his calculation on ten killings when in fact 9 killings are reported. In the time between 1936 and 1950 not 10 but 9 Casiguran Agta were killed - 1 in 1950, 5 in 1947; 1 in1938 raid and 2 “shortly after World War II”. Bowles therefore miscalculated his data and Pinker carries this wrong number over.As Headlands study of the Agta focusses on a later time (1962-84) I take the data from this better researched time. As Headland states that the latter half of his research stay (post-1977) was a time of 'unusual high violence' I quote the death rate due to violence from the earlier time (1962-77). In this more 'peaceful' time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta - which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: 'In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year. The 14 homicides on which this calculation is based include only homicides of members of the de jure population.' (page 68). <p>He also notes that 'of the 33 Agta deaths by homicide since my arrival in 1962 up to June 1984, only eight were killed by non-Agta. Of the 14 Agta homicides in the de jure population in 1977-1984, only five were killed by non-Agta. Of the 53 homicides, only 30% of the victims were killed by non-Agta (16153)</p>And he says: 'It should be noted here that Agta kill outsiders, too. I know of 24 cases of Agta killing non-Agta since 1930 and 15 cases since I began fieldwork in the area in 1962.'

A.D. 1325). The attack seems to have occurred just when the village's fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village's population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives.

In this more 'peaceful' time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta - which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: 'In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year.

on archaeological and ethnographic studies. [Homicide rates](https://ourworldindata.org/homicides/) for modern times are routinely published by statistical offices or other state agencies, and research institutes publish [reliable data on war deaths](https://ourworldindata.org/war-and-peace-after-1945/). For the study of lethal violence in non-state societies we have generally two different sources of information: for the more recent past (since the late 19th century) ethnographic evidence is abundant. For the more distant past, we have information on the prevalence of violence from archeologists who have studied violence in past societies through skeletal remains at archeological sites. We present and describe data from both archaeological and ethnographic studies below. Importantly, this is not all the information we have on violence in different societies. Non-quantitative information on violence is abundant, such as in art. And both types of studies often cannot distinguish between whether a violent death was inflicted by a member of the same group or by another, and therefore is more similar to what we think of today as a homicide or a death from war. We see that the levels of violence in prehistoric times and in non-state societies differ widely between societies. But on average they tend to be significantly higher than in modern state societies and the world today. ## Rate of Violent Deaths in State and Non-State Societies <Chart url="https://ourworldindata.org/grapher/rate-of-violent-deaths-non-state-societies"/> <Chart url="https://ourworldindata.org/grapher/rate-of-violent-deaths-state-societies"/> ## Share of Violent Deaths in Prehistoric, State and Non-State Societies <Chart url="https://ourworldindata.org/grapher/share-of-violent-deaths-prehistoric-archeological-sites"/> <Chart url="https://ourworldindata.org/grapher/share-of-violent-deaths-non-state-societies"/> <Chart url="https://ourworldindata.org/grapher/share-of-violent-deaths-state-societies"/> ## Data Sources This section collects all of the ethnographic and archaeological data sources on violent deaths presented above. ### Procedures in collecting this data The starting point for my research was the sample presented by Pinker (2011).{ref}Pinker (2011) - The Better Angels of Our Nature: Why Violence Has Declined. {/ref} Pinker does not present the numerical data itself but instead includes two bar charts (Figures 2-2 and 2-3) from which the exact data cannot be discerned. Therefore I looked up all the sources for the data he presents. The topic of Pinker's book is the decline of violence in humanity's history. That would give him an incentive to cherry-pick data that suits his narrative. For this reason I had contact with several of his critics and asked them for their evidence. After this assessment of Pinker's data, I did not find any reason to assume that he cherry-picked. He included all the data that his sources included. Through my contact with critics of Pinker's book I was referred to a critique of Pinker's data by Douglas Fry.{ref}Fry (2013) - Chapter 1: War, Peace, and Human Nature. The Challenge of Scientific Objectivity. In War, Peace, and Human Nature: The Convergence of Evolutionary and Cultural Views. Edited by Douglas Fry. Oxford University Press. New York.{/ref} Fry criticizes some of Pinker's data. I checked the original sources for the criticized information, referred to the criticisms and the original sources in my comments and corrected the data when the criticism was justified. An additional source that I added to my dataset and which was not yet available to Pinker is a study published by Robert Walker and Drew Bailey (published in 2013).{ref}Walker and Bailey (2013) - Body counts in lowland South American violence. In Evolution and Human Behavior, 34, 1, 29--34.{/ref} The main sources are the following: I checked the following sources and collected the data these sources presented. For every information I also included the original source: * Bowles (2009) - Did Warfare Among Ancestral Hunter-Gatherers Affect the Evolution of Human Social Behaviors?. In Science, 324, 5932, 1293--1298. * Gat (2006) - War in Human Civilization.

(Middle Missouri) Zimmerman 1980; Wilky 1990; Bamforth 1994; (Southwest) Haas 1990: 187, and personal communication.) For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilaced during an attack on their village a century and a hdf before Columbus's arrival (ca. A.D. 1325). The attack seems to have occurred just when the village's fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village's population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilared in a single attack and never reoccupied.'

Between 1977 and 1984 the homicide rate is 326 homicides per 100,000 people per year. In this time period, that was described as unusually violent (and which is therefore not quoted in my statistic) 21% of all adult male deaths were due to homicide (see comment). * _Original source:_[Headland, T. (1989) - Population decline in a Philippine Negrito hunter-gatherer Society. American Journal of Human Biology, 1, 59–72.](https://onlinelibrary.wiley.com/doi/10.1002/ajhb.1310010111/full) * _Comment:_ The source of Pinker on the percentage of deaths in warfare is Bowles (2009) and he made a mistake that Fry (2013) corrects: Bowles (2009) based his calculation on ten killings when in fact 9 killings are reported. In the time between 1936 and 1950 not 10 but 9 Casiguran Agta were killed - 1 in 1950, 5 in 1947; 1 in1938 raid and 2 “shortly after World War II”. Bowles therefore miscalculated his data and Pinker carries this wrong number over.As Headlands study of the Agta focusses on a later time (1962-84) I take the data from this better researched time. As Headland states that the latter half of his research stay (post-1977) was a time of 'unusual high violence' I quote the death rate due to violence from the earlier time (1962-77). In this more 'peaceful' time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta - which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: 'In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year. The 14 homicides on which this calculation is based include only homicides of members of the de jure population.' (page 68). He also notes that 'of the 33 Agta deaths by homicide since my arrival in 1962 up to June 1984, only eight were killed by non-Agta. Of the 14 Agta homicides in the de jure population in 1977-1984, only five were killed by non-Agta. Of the 53 homicides, only 30% of the victims were killed by non-Agta (16153)And he says: 'It should be noted here that Agta kill outsiders, too. I know of 24 cases of Agta killing non-Agta since 1930 and 15 cases since I began fieldwork in the area in 1962.'

Table 4 (page 450) shows the statistics on both groups and makes an additional distinction between precontact and postcontact times. In the precontact times 153 deaths are tabulated. There were 11 killings of Hiwi by Hiwi in the precontact times. Out of the 160 killings in the postcontact times 6 were killings of Hiwi by Hiwi. The Source that my source quoted states: "The Hiwi mortality proﬁle is characterized by notably high rates of violence and accidental trauma" (page 449)The numbers I quoted and the share of violent deaths is not counting infanticides that were very common among the Hiwi (and are reported by Hill, Hurtado (2007)).

Pinker quotes the 10%, which according to Gat (2006) only refers to the male population. I decided to quote the average of the two shares specified for the entire population. That is 5.75%.

It is [available online](http://web.undp.org/evaluation/documents/thematic/conflict/chapter2.pdf)The last year that we have data for is 2007. These are the numbers by category:Number of State-Based Battle Deaths: 16773 Number of Non-State Battle Deaths: 1865Number of One Sided Violence Deaths: 3501The total sum of the above is: 22139 deathsThe world population in 2007 was 6.658.000.000 (World Bank) - The death rate of the world is approximately 8 per 1000 per year according to the [CIA Factbook](https://web.archive.org/web/20130723121132/https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html). This means around 53264000 people died in 2007. Therefore the ratio of people dying due to warfare in 2007 is 22139/53264000. This means 0.04% of the global deaths were due to warfare in 2007.	{ "id": 2589, "date": "2013-08-02T19:27:18", "guid": { "rendered": "http://ourworldindata.org/?page_id=2589" }, "link": "https://owid.cloud/ethnographic-and-archaeological-evidence-on-violent-deaths", "meta": { "owid_publication_context_meta_field": { "latest": false, "homepage": false, "immediate_newsletter": false } }, "slug": "ethnographic-and-archaeological-evidence-on-violent-deaths", "tags": [], "type": "post", "title": { "rendered": "Data Review: Ethnographic and archaeological evidence on violent deaths" }, "_links": { "self": [ { "href": "https://owid.cloud/wp-json/wp/v2/posts/2589" } ], "about": [ { "href": "https://owid.cloud/wp-json/wp/v2/types/post" } ], "author": [ { "href": "https://owid.cloud/wp-json/wp/v2/users/2", "embeddable": true } ], "curies": [ { "href": "https://api.w.org/{rel}", "name": "wp", "templated": true } ], "replies": [ { "href": "https://owid.cloud/wp-json/wp/v2/comments?post=2589", "embeddable": true } ], "wp:term": [ { "href": "https://owid.cloud/wp-json/wp/v2/categories?post=2589", "taxonomy": "category", "embeddable": true }, { "href": "https://owid.cloud/wp-json/wp/v2/tags?post=2589", "taxonomy": "post_tag", "embeddable": true } ], "collection": [ { "href": "https://owid.cloud/wp-json/wp/v2/posts" } ], "wp:attachment": [ { "href": "https://owid.cloud/wp-json/wp/v2/media?parent=2589" } ], "version-history": [ { "href": "https://owid.cloud/wp-json/wp/v2/posts/2589/revisions", "count": 30 } ], "wp:featuredmedia": [ { "href": "https://owid.cloud/wp-json/wp/v2/media/56136", "embeddable": true } ], "predecessor-version": [ { "id": 56139, "href": "https://owid.cloud/wp-json/wp/v2/posts/2589/revisions/56139" } ] }, "author": 2, "format": "standard", "status": "publish", "sticky": false, "content": { "rendered": "\n<p>This Data Review presents quantitative information on violent deaths based on archaeological and ethnographic studies.</p>\n\n\n\n<p><a title=\"Homicides\" href=\"https://ourworldindata.org/homicides/\">Homicide rates</a> for modern times are routinely published by statistical offices or other state agencies, and research institutes publish <a title=\"War and Peace after 1945\" href=\"https://ourworldindata.org/war-and-peace-after-1945/\">reliable data on war deaths</a>.</p>\n\n\n\n<p>For the study of lethal violence in non-state societies we have generally two different sources of information: for the more recent past (since the late 19th century) ethnographic evidence is abundant. </p>\n\n\n\n<p>For the more distant past, we have information on the prevalence of violence from archeologists who have studied violence in past societies through skeletal remains at archeological sites.</p>\n\n\n\n<p>We present and describe data from both archaeological and ethnographic studies below.</p>\n\n\n\n<p>Importantly, this is not all the information we have on violence in different societies.

That would give him an incentive to cherry-pick data that suits his narrative. For this reason I had contact with several of his critics and asked them for their evidence. After this assessment of Pinker’s data, I did not find any reason to assume that he cherry-picked. He included all the data that his sources included.</p>\n\n\n\n<p>Through my contact with critics of Pinker’s book I was referred to a critique of Pinker’s data by Douglas Fry.{ref}Fry (2013) – Chapter 1: War, Peace, and Human Nature.

(Middle Missouri) Zimmerman 1980; Wilky 1990; Bamforth 1994; (Southwest) Haas 1990: 187, and personal communication.) For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilaced during an attack on their village a century and a hdf before Columbus’s arrival (ca. A.D. 1325). The attack seems to have occurred just when the village’s fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village’s population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilared in a single attack and never reoccupied.’</li></ul>\n\n\n\n<p><strong>Site:</strong> Nubia (site 117), 14-12000 years before present <strong>Share of Violent Deaths:</strong> 46%</p>\n\n\n\n<ul><li><em>My source for the data:</em> Bowles (2009)</li><li><em>Comment and sources:</em> Bowles (2009) quotes F.

(1989) – Population decline in a Philippine Negrito hunter-gatherer Society. American Journal of Human Biology, 1, 59\u201372.</a></li><li><em>Comment:</em> The source of Pinker on the percentage of deaths in warfare is Bowles (2009) and he made a mistake that Fry (2013) corrects: Bowles (2009) based his calculation on ten killings when in fact 9 killings are reported. In the time between 1936 and 1950 not 10 but 9 Casiguran Agta were killed – 1 in 1950, 5 in 1947; 1 in1938 raid and 2 \u201cshortly after World War II\u201d. Bowles therefore miscalculated his data and Pinker carries this wrong number over.As Headlands study of the Agta focusses on a later time (1962-84) I take the data from this better researched time. As Headland states that the latter half of his research stay (post-1977) was a time of ‘unusual high violence’ I quote the death rate due to violence from the earlier time (1962-77). In this more ‘peaceful’ time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta – which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: ‘In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year. The 14 homicides on which this calculation is based include only homicides of members of the de jure population.’ (page 68). <p>He also notes that ‘of the 33 Agta deaths by homicide since my arrival in 1962 up to June 1984, only eight were killed by non-Agta. Of the 14 Agta homicides in the de jure population in 1977-1984, only five were killed by non-Agta. Of the 53 homicides, only 30% of the victims were killed by non-Agta (16153)</p>And he says: ‘It should be noted here that Agta kill outsiders, too. I know of 24 cases of Agta killing non-Agta since 1930 and 15 cases since I began fieldwork in the area in 1962.’ (page 69) </li></ul>\n\n\n\n<p><strong>Society:</strong> Anggor <strong>Share of Violent Deaths:</strong> 11.9%</p>\n\n\n\n<ul><li><em>My source for the data:</em> Keeley (1996)</li><li><em>Source that my source quoted:</em> Huber, P. 1973. “Defending the Cosmos: Violence and Social Order Among the Anggor of New Guinea.” In War, Its Causes and Correlates, ed.

Data Review: Ethnographic and archaeological evidence on violent deaths

This Data Review presents quantitative information on violent deaths based on archaeological and ethnographic studies.   <a title="Homicides" href="https://ourworldindata.org/homicides/">Homicide rates</a> for modern times are routinely published by statistical offices or other state agencies, and research institutes publish <a title="War and Peace after 1945" href="https://ourworldindata.org/war-and-peace-after-1945/">reliable data on war deaths</a>.   For the study of lethal violence in non-state societies we have generally two different sources of information: for the more recent past (since the late 19th century) ethnographic evidence is abundant.   For the more distant past, we have information on the prevalence of violence from archeologists who have studied violence in past societies through skeletal remains at archeological sites.   We present and describe data from both archaeological and ethnographic studies below.   Importantly, this is not all the information we have on violence in different societies. Non-quantitative information on violence is abundant, such as in art.   And both types of studies often cannot distinguish between whether a violent death was inflicted by a member of the same group or by another, and therefore is more similar to what we think of today as a homicide or a death from war.   We see that the levels of violence in prehistoric times and in non-state societies differ widely between societies. But on average they tend to be significantly higher than in modern state societies and the world today.     <h4>Rate of Violent Deaths in State and Non-State Societies</h4>   <iframe src="https://ourworldindata.org/grapher/rate-of-violent-deaths-non-state-societies" style="width: 100%; height: 600px; border: 0px none;"></iframe>   <iframe src="https://ourworldindata.org/grapher/rate-of-violent-deaths-state-societies" style="width: 100%; height: 600px; border: 0px none;"></iframe>   <h4>Share of Violent Deaths in Prehistoric, State and Non-State Societies</h4>   <iframe src="https://ourworldindata.org/grapher/share-of-violent-deaths-prehistoric-archeological-sites" style="width: 100%; height: 600px; border: 0px none;"></iframe>   <iframe src="https://ourworldindata.org/grapher/share-of-violent-deaths-non-state-societies" style="width: 100%; height: 600px; border: 0px none;"></iframe>   <iframe src="https://ourworldindata.org/grapher/share-of-violent-deaths-state-societies" style="width: 100%; height: 600px; border: 0px none;"></iframe>   <h4>Data Sources</h4>   This section collects all of the ethnographic and archaeological data sources on violent deaths presented above.   <h5>Procedures in collecting this data</h5>   The starting point for my research was the sample presented by Pinker (2011).{ref}Pinker (2011) - The Better Angels of Our Nature: Why Violence Has Declined. {/ref} Pinker does not present the numerical data itself but instead includes two bar charts (Figures 2-2 and 2-3) from which the exact data cannot be discerned. Therefore I looked up all the sources for the data he presents.   The topic of Pinker's book is the decline of violence in humanity's history. That would give him an incentive to cherry-pick data that suits his narrative. For this reason I had contact with several of his critics and asked them for their evidence. After this assessment of Pinker's data, I did not find any reason to assume that he cherry-picked. He included all the data that his sources included.   Through my contact with critics of Pinker's book I was referred to a critique of Pinker's data by Douglas Fry.{ref}Fry (2013) - Chapter 1: War, Peace, and Human Nature. The Challenge of Scientific Objectivity. In War, Peace, and Human Nature: The Convergence of Evolutionary and Cultural Views. Edited by Douglas Fry. Oxford University Press. New York.{/ref} Fry criticizes some of Pinker's data. I checked the original sources for the criticized information, referred to the criticisms and the original sources in my comments and corrected the data when the criticism was justified.   An additional source that I added to my dataset and which was not yet available to Pinker is a study published by Robert Walker and Drew Bailey (published in 2013).{ref}Walker and Bailey (2013) - Body counts in lowland South American violence. In Evolution and Human Behavior, 34, 1, 29--34.{/ref}   The main sources are the following:   I checked the following sources and collected the data these sources presented.

(Middle Missouri) Zimmerman 1980; Wilky 1990; Bamforth 1994; (Southwest) Haas 1990: 187, and personal communication.) For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilaced during an attack on their village a century and a hdf before Columbus's arrival (ca. A.D. 1325). The attack seems to have occurred just when the village's fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village's population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilared in a single attack and never reoccupied.'</li></ul>   Site: Nubia (site 117), 14-12000 years before present Share of Violent Deaths: 46%   <ul><li>My source for the data: Bowles (2009)</li><li>Comment and sources: Bowles (2009) quotes F.

(1989) - Population decline in a Philippine Negrito hunter-gatherer Society. American Journal of Human Biology, 1, 59–72.</a></li><li>Comment: The source of Pinker on the percentage of deaths in warfare is Bowles (2009) and he made a mistake that Fry (2013) corrects: Bowles (2009) based his calculation on ten killings when in fact 9 killings are reported. In the time between 1936 and 1950 not 10 but 9 Casiguran Agta were killed - 1 in 1950, 5 in 1947; 1 in1938 raid and 2 “shortly after World War II”. Bowles therefore miscalculated his data and Pinker carries this wrong number over.As Headlands study of the Agta focusses on a later time (1962-84) I take the data from this better researched time. As Headland states that the latter half of his research stay (post-1977) was a time of 'unusual high violence' I quote the death rate due to violence from the earlier time (1962-77). In this more 'peaceful' time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta - which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: 'In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year. The 14 homicides on which this calculation is based include only homicides of members of the de jure population.' (page 68). He also notes that 'of the 33 Agta deaths by homicide since my arrival in 1962 up to June 1984, only eight were killed by non-Agta. Of the 14 Agta homicides in the de jure population in 1977-1984, only five were killed by non-Agta. Of the 53 homicides, only 30% of the victims were killed by non-Agta (16153)And he says: 'It should be noted here that Agta kill outsiders, too. I know of 24 cases of Agta killing non-Agta since 1930 and 15 cases since I began fieldwork in the area in 1962.'

Table 4 (page 450) shows the statistics on both groups and makes an additional distinction between precontact and postcontact times. In the precontact times 153 deaths are tabulated. There were 11 killings of Hiwi by Hiwi in the precontact times. Out of the 160 killings in the postcontact times 6 were killings of Hiwi by Hiwi. The Source that my source quoted states: "The Hiwi mortality proﬁle is characterized by notably high rates of violence and accidental trauma" (page 449)The numbers I quoted and the share of violent deaths is not counting infanticides that were very common among the Hiwi (and are reported by Hill, Hurtado (2007)).</li></ul>   Society: Tsimane Share of Violent Deaths: 6% (adults)   <ul><li>My source for the data: Walker and Bailey (2013)</li><li>Source that my source quoted: M.

Pinker quotes the 10%, which according to Gat (2006) only refers to the male population. I decided to quote the average of the two shares specified for the entire population.

These are the numbers by category:Number of State-Based Battle Deaths: 16773 Number of Non-State Battle Deaths: 1865Number of One Sided Violence Deaths: 3501The total sum of the above is: 22139 deathsThe world population in 2007 was 6.658.000.000 (World Bank) - The death rate of the world is approximately 8 per 1000 per year according to the <a href="https://web.archive.org/web/20130723121132/https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html">CIA Factbook</a>. This means around 53264000 people died in 2007. Therefore the ratio of people dying due to warfare in 2007 is 22139/53264000. This means 0.04% of the global deaths were due to warfare in 2007.</li></ul>

(Middle Missouri) Zimmerman 1980; Wilky 1990; Bamforth 1994; (Southwest) Haas 1990: 187, and personal communication.) For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilaced during an attack on their village a century and a hdf before Columbus's arrival (ca. A.D. 1325). The attack seems to have occurred just when the village's fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village's population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilared in a single attack and never reoccupied.'",

In the time between 1936 and 1950 not 10 but 9 Casiguran Agta were killed - 1 in 1950, 5 in 1947; 1 in1938 raid and 2 \u201cshortly after World War II\u201d. Bowles therefore miscalculated his data and Pinker carries this wrong number over.As Headlands study of the Agta focusses on a later time (1962-84) I take the data from this better researched time. As Headland states that the latter half of his research stay (post-1977) was a time of 'unusual high violence' I quote the death rate due to violence from the earlier time (1962-77). In this more 'peaceful' time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta - which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: 'In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year. The 14 homicides on which this calculation is based include only homicides of members of the de jure population.' (page 68). ",

There were 11 killings of Hiwi by Hiwi in the precontact times. Out of the 160 killings in the postcontact times 6 were killings of Hiwi by Hiwi. The Source that my source quoted states: \"The Hiwi mortality pro\ufb01le is characterized by notably high rates of violence and accidental trauma\" (page 449)The numbers I quoted and the share of violent deaths is not counting infanticides that were very common among the Hiwi (and are reported by Hill, Hurtado (2007)).",

This Data Review presents quantitative information on violent deaths based on archaeological and ethnographic studies. [Homicide rates](https://ourworldindata.org/homicides/) for modern times are routinely published by statistical offices or other state agencies, and research institutes publish [reliable data on war deaths](https://ourworldindata.org/war-and-peace-after-1945/). For the study of lethal violence in non-state societies we have generally two different sources of information: for the more recent past (since the late 19th century) ethnographic evidence is abundant. For the more distant past, we have information on the prevalence of violence from archeologists who have studied violence in past societies through skeletal remains at archeological sites. We present and describe data from both archaeological and ethnographic studies below. Importantly, this is not all the information we have on violence in different societies. Non-quantitative information on violence is abundant, such as in art. And both types of studies often cannot distinguish between whether a violent death was inflicted by a member of the same group or by another, and therefore is more similar to what we think of today as a homicide or a death from war. We see that the levels of violence in prehistoric times and in non-state societies differ widely between societies. But on average they tend to be significantly higher than in modern state societies and the world today. ## Rate of Violent Deaths in State and Non-State Societies <Chart url="https://ourworldindata.org/grapher/rate-of-violent-deaths-non-state-societies"/> <Chart url="https://ourworldindata.org/grapher/rate-of-violent-deaths-state-societies"/> ## Share of Violent Deaths in Prehistoric, State and Non-State Societies <Chart url="https://ourworldindata.org/grapher/share-of-violent-deaths-prehistoric-archeological-sites"/> <Chart url="https://ourworldindata.org/grapher/share-of-violent-deaths-non-state-societies"/> <Chart url="https://ourworldindata.org/grapher/share-of-violent-deaths-state-societies"/> ## Data Sources This section collects all of the ethnographic and archaeological data sources on violent deaths presented above. ### **Procedures in collecting this data** The starting point for my research was the sample presented by Pinker (2011).{ref}Pinker (2011) - The Better Angels of Our Nature: Why Violence Has Declined. {/ref} Pinker does not present the numerical data itself but instead includes two bar charts (Figures 2-2 and 2-3) from which the exact data cannot be discerned. Therefore I looked up all the sources for the data he presents. The topic of Pinker's book is the decline of violence in humanity's history. That would give him an incentive to cherry-pick data that suits his narrative. For this reason I had contact with several of his critics and asked them for their evidence. After this assessment of Pinker's data, I did not find any reason to assume that he cherry-picked. He included all the data that his sources included. Through my contact with critics of Pinker's book I was referred to a critique of Pinker's data by Douglas Fry.{ref}Fry (2013) - Chapter 1: War, Peace, and Human Nature. The Challenge of Scientific Objectivity. In War, Peace, and Human Nature: The Convergence of Evolutionary and Cultural Views. Edited by Douglas Fry. Oxford University Press. New York.{/ref} Fry criticizes some of Pinker's data. I checked the original sources for the criticized information, referred to the criticisms and the original sources in my comments and corrected the data when the criticism was justified. An additional source that I added to my dataset and which was not yet available to Pinker is a study published by Robert Walker and Drew Bailey (published in 2013).{ref}Walker and Bailey (2013) - Body counts in lowland South American violence. In Evolution and Human Behavior, 34, 1, 29--34.{/ref} **The main sources are the following:** I checked the following sources and collected the data these sources presented. For every information I also included the original source: * Bowles (2009) - Did Warfare Among Ancestral Hunter-Gatherers Affect the Evolution of Human Social Behaviors?. In Science, 324, 5932, 1293--1298. * Gat (2006) - War in Human Civilization.

(Middle Missouri) Zimmerman 1980; Wilky 1990; Bamforth 1994; (Southwest) Haas 1990: 187, and personal communication.) For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilaced during an attack on their village a century and a hdf before Columbus's arrival (ca. A.D. 1325). The attack seems to have occurred just when the village's fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village's population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilared in a single attack and never reoccupied.' **Site:** Nubia (site 117), 14-12000 years before present **Share of Violent Deaths:** 46% * _My source for the data:_ Bowles (2009) * _Comment and sources:_ Bowles (2009) quotes F.

Between 1977 and 1984 the homicide rate is 326 homicides per 100,000 people per year. In this time period, that was described as unusually violent (and which is therefore not quoted in my statistic) 21% of all adult male deaths were due to homicide (see comment). * _Original source:_[Headland, T. (1989) - Population decline in a Philippine Negrito hunter-gatherer Society. American Journal of Human Biology, 1, 59–72.](https://onlinelibrary.wiley.com/doi/10.1002/ajhb.1310010111/full) * _Comment:_ The source of Pinker on the percentage of deaths in warfare is Bowles (2009) and he made a mistake that Fry (2013) corrects: Bowles (2009) based his calculation on ten killings when in fact 9 killings are reported. In the time between 1936 and 1950 not 10 but 9 Casiguran Agta were killed - 1 in 1950, 5 in 1947; 1 in1938 raid and 2 “shortly after World War II”. Bowles therefore miscalculated his data and Pinker carries this wrong number over.As Headlands study of the Agta focusses on a later time (1962-84) I take the data from this better researched time. As Headland states that the latter half of his research stay (post-1977) was a time of 'unusual high violence' I quote the death rate due to violence from the earlier time (1962-77). In this more 'peaceful' time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta - which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: 'In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year. The 14 homicides on which this calculation is based include only homicides of members of the de jure population.' (page 68). He also notes that 'of the 33 Agta deaths by homicide since my arrival in 1962 up to June 1984, only eight were killed by non-Agta. Of the 14 Agta homicides in the de jure population in 1977-1984, only five were killed by non-Agta. Of the 53 homicides, only 30% of the victims were killed by non-Agta (16153)And he says: 'It should be noted here that Agta kill outsiders, too. I know of 24 cases of Agta killing non-Agta since 1930 and 15 cases since I began fieldwork in the area in 1962.'

Table 4 (page 450) shows the statistics on both groups and makes an additional distinction between precontact and postcontact times. In the precontact times 153 deaths are tabulated. There were 11 killings of Hiwi by Hiwi in the precontact times. Out of the 160 killings in the postcontact times 6 were killings of Hiwi by Hiwi. The Source that my source quoted states: "The Hiwi mortality proﬁle is characterized by notably high rates of violence and accidental trauma" (page 449)The numbers I quoted and the share of violent deaths is not counting infanticides that were very common among the Hiwi (and are reported by Hill, Hurtado (2007)). **Society:** Tsimane **Share of Violent Deaths:** 6% (adults) * _My source for the data:_ Walker and Bailey (2013) * _Source that my source quoted:_ M.

G. Kimber, ‘Hunter-gatherer demography: The recent past in Central Australia’, in B. Meehan and N. White (eds), Hunter-Gatherer Demography. Sydney: University of Sydney, 1990, p. 163.Gat (2006) refers to Pilling saying: 'Pilling’s estimate of at least 10 per cent killed among the Tiwi men in one decade.'Gat (2006) refers to Kimber saying: 'Kimber’s estimate, for a generation, of 5 per cent mortality in ﬁghting in arid areas and about 6.5 per cent in well-watered ones refers to violent mortality in relation to the entire population’s overall mortality rates.' Pinker quotes the 10%, which according to Gat (2006) only refers to the male population. I decided to quote the average of the two shares specified for the entire population.

It is [available online](http://web.undp.org/evaluation/documents/thematic/conflict/chapter2.pdf)The last year that we have data for is 2007. These are the numbers by category:Number of State-Based Battle Deaths: 16773 Number of Non-State Battle Deaths: 1865Number of One Sided Violence Deaths: 3501The total sum of the above is: 22139 deathsThe world population in 2007 was 6.658.000.000 (World Bank) - The death rate of the world is approximately 8 per 1000 per year according to the [CIA Factbook](https://web.archive.org/web/20130723121132/https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html). This means around 53264000 people died in 2007. Therefore the ratio of people dying due to warfare in 2007 is 22139/53264000. This means 0.04% of the global deaths were due to warfare in 2007.

Non-quantitative information on violence is abundant, such as in art.</p>\n\n\n\n<p>And both types of studies often cannot distinguish between whether a violent death was inflicted by a member of the same group or by another, and therefore is more similar to what we think of today as a homicide or a death from war.</p>\n\n\n\n<p>We see that the levels of violence in prehistoric times and in non-state societies differ widely between societies. But on average they tend to be significantly higher than in modern state societies and the world today.</p>\n\n\n\n<p></p>\n\n\n\n<h4>Rate of Violent Deaths in State and Non-State Societies</h4>\n\n\n\n<iframe src=\"https://ourworldindata.org/grapher/rate-of-violent-deaths-non-state-societies\" style=\"width: 100%; height: 600px; border: 0px none;\"></iframe>\n\n\n\n<iframe src=\"https://ourworldindata.org/grapher/rate-of-violent-deaths-state-societies\" style=\"width: 100%; height: 600px; border: 0px none;\"></iframe>\n\n\n\n<h4>Share of Violent Deaths in Prehistoric, State and Non-State Societies</h4>\n\n\n\n<iframe src=\"https://ourworldindata.org/grapher/share-of-violent-deaths-prehistoric-archeological-sites\" style=\"width: 100%; height: 600px; border: 0px none;\"></iframe>\n\n\n\n<iframe src=\"https://ourworldindata.org/grapher/share-of-violent-deaths-non-state-societies\" style=\"width: 100%; height: 600px; border: 0px none;\"></iframe>\n\n\n\n<iframe src=\"https://ourworldindata.org/grapher/share-of-violent-deaths-state-societies\" style=\"width: 100%; height: 600px; border: 0px none;\"></iframe>\n\n\n\n<h4>Data Sources</h4>\n\n\n\n<p>This section collects all of the ethnographic and archaeological data sources on violent deaths presented above.</p>\n\n\n\n<h5><strong>Procedures in collecting this data</strong></h5>\n\n\n\n<p>The starting point for my research was the sample presented by Pinker (2011).{ref}Pinker (2011) &#8211; The Better Angels of Our Nature: Why Violence Has Declined. {/ref} Pinker does not present the numerical data itself but instead includes two bar charts (Figures 2-2 and 2-3) from which the exact data cannot be discerned. Therefore I looked up all the sources for the data he presents.</p>\n\n\n\n<p>The topic of Pinker&#8217;s book is the decline of violence in humanity&#8217;s history. That would give him an incentive to cherry-pick data that suits his narrative. For this reason I had contact with several of his critics and asked them for their evidence. After this assessment&nbsp;of Pinker&#8217;s data, I did not find any reason to assume that he cherry-picked. He included all the data that his sources included.</p>\n\n\n\n<p>Through my contact with critics of Pinker&#8217;s book I was referred to a critique of Pinker&#8217;s data by Douglas Fry.{ref}Fry (2013) &#8211; Chapter 1: War, Peace, and Human Nature.

(Middle Missouri) Zimmerman 1980; Wilky 1990; Bamforth 1994; (Southwest) Haas 1990: 187, and personal communication.) For example, at Crow Creek in South Dakota, archaeologists found a mass grave containing the remains of more than 500 men, women, and children who had been slaughtered, scalped, and mutilaced during an attack on their village a century and a hdf before Columbus&#8217;s arrival (ca. A.D. 1325). The attack seems to have occurred just when the village&#8217;s fortifications were being rebuilt. AU the houses were burned, and most of the inhabitants were murdered. This death toll represented more than 60 percent of the village&#8217;s population, estimated from the number of houses to have been about 800. The survivors appear to have been primarily young women, as their skeletons are underrepresented among the bones; if so, they were probably taken away as captives. Certainly, the site was deserted for some time after the attack because the bodies evidently remained exposed to scavenging animals for a few weeks before burial. In other words, this whole village was annihilared in a single attack and never reoccupied.&#8217;</li></ul>\n\n\n\n<p><strong>Site:</strong> Nubia (site 117), 14-12000 years before present <strong>Share of Violent Deaths:</strong> 46%</p>\n\n\n\n<ul><li><em>My source for the data:</em> Bowles (2009)</li><li><em>Comment and sources:</em> Bowles (2009) quotes F.

In this time period, that was described as unusually violent (and which is therefore not quoted in my statistic) 21% of all adult male deaths were due to homicide (see comment).</p>\n\n\n\n<ul><li><em>Original source:</em> <a href=\"https://onlinelibrary.wiley.com/doi/10.1002/ajhb.1310010111/full\">Headland, T. (1989) &#8211; Population decline in a Philippine Negrito hunter-gatherer Society. American Journal of Human Biology, 1, 59\u201372.</a></li><li><em>Comment:</em> The source of Pinker on the percentage of deaths in warfare is Bowles (2009) and he made a mistake that Fry (2013) corrects: Bowles (2009) based his calculation on ten killings when in fact 9 killings are reported. In the time between 1936 and 1950 not 10 but 9 Casiguran Agta were killed &#8211; 1 in 1950, 5 in 1947; 1 in1938 raid and 2 \u201cshortly after World War II\u201d. Bowles therefore miscalculated his data and Pinker carries this wrong number over.As Headlands study of the Agta focusses on a later time (1962-84) I take the data from this better researched time. As Headland states that the latter half of his research stay (post-1977) was a time of &#8216;unusual high violence&#8217; I quote the death rate due to violence from the earlier time (1962-77). In this more &#8216;peaceful&#8217; time the share of violent deaths was 12% (and this also is not counting the number of killings of non-Agta by Agta &#8211; which is also high (see below)).Homicides, as opposed to deaths in warfare are very common in the Agta Population as Headland points out: &#8216;In the sample of adult male deaths before 1977, 12% were attributed to homicide; in 1977-1984, 21% of all adult male deaths were from homicide. The overall homicide rate for the Casiguran Agta, based on the data for 1977-1984, is 326 homicides per 100,000 people per year. The 14 homicides on which this calculation is based include only homicides of members of the de jure population.&#8217; (page 68). <p>He also notes that &#8216;of the 33 Agta deaths by homicide since my arrival in 1962 up to June 1984, only eight were killed by non-Agta. Of the 14 Agta homicides in the de jure population in 1977-1984, only five were killed by non-Agta. Of the 53 homicides, only 30% of the victims were killed by non-Agta (16153)</p>And he says: &#8216;It should be noted here that Agta kill outsiders, too. I know of 24 cases of Agta killing non-Agta since 1930 and 15 cases since I began fieldwork in the area in 1962.&#8217; (page 69) </li></ul>\n\n\n\n<p><strong>Society:</strong> Anggor <strong>Share of Violent Deaths:</strong> 11.9%</p>\n\n\n\n<ul><li><em>My source for the data:</em> Keeley (1996)</li><li><em>Source that my source quoted:</em> Huber, P. 1973. &#8220;Defending the Cosmos: Violence and Social Order Among the Anggor of New Guinea.&#8221; In War, Its Causes and Correlates, ed.

It is <a href=\"http://web.undp.org/evaluation/documents/thematic/conflict/chapter2.pdf\">available online</a>The last year that we have data for is 2007. These are the numbers by category:Number of State-Based Battle Deaths: 16773 <p>Number of Non-State Battle Deaths: 1865Number of One Sided Violence Deaths: 3501The total sum of the above is: 22139 deathsThe world population in 2007 was 6.658.000.000 (World Bank) &#8211; The death rate of the world is approximately 8 per 1000 per year according to the <a href=\"https://web.archive.org/web/20130723121132/https://www.cia.gov/library/publications/the-world-factbook/geos/xx.html\">CIA Factbook</a>. This means around 53264000 people died in 2007. Therefore the ratio of people dying due to warfare in 2007 is 22139/53264000. This means 0.04% of the global deaths were due to warfare in 2007.</p></li></ul>\n",
