These measures were implemented to slow the spread of the virus by enforcing physical distance between people. How effective have these policies been in reducing human movement? What impact has it had on how people across the world work; live; and where they visit? We can get some insights on this from the data that Google presents in its _[COVID-19 Community Mobility Reports](https://www.google.com/covid19/mobility/)_. Using anonymized data provided by apps such as Google Maps, the company has produced a regularly updated dataset that shows how peoples' movements have changed throughout the pandemic.1 This dataset from Google measures visitor numbers to specific categories of location (e.g. grocery stores; parks; train stations) every day and compares this change relative to baseline days before the pandemic outbreak. Baseline days represent a normal value for that day of the week and are given as the median value over the five‑week period from January 3rd to February 6th 2020. Measuring it relative to a normal value _for that day of the week_ is helpful because people obviously often have different routines on weekends versus weekdays. On Google's website the data is only visualized in pdfs – one for each country. We present Google's data in interactive charts below to make it easier to see changes over time in a given country; and how specific policies may have affected (or not) behavior across communities. Google notes that we should avoid comparing across regions or countries; this is because there may be local differences in categories which could be misleading. We should also emphasise that change in visitors is measured relative to the baseline period between January and February 2020. This means changes in movement do not take account of seasonal variation – for example, we might expect visitors to parks or outdoor spaces to be higher during the summer. The data may therefore reflect some changes in seasonal movements, rather than being fully explained by changes due to the pandemic. The amount of day-to-day variability in the raw data can make it difficult to understand how overall movements are changing over time. To make this easier to understand, we have converted the raw data into the **seven-day rolling average**. This is what is shown in the data in the following charts. # Change in visitors by category This interactive chart shows how the number of visitors (or time spent) in categorized places has changed compared to baseline days (the median value for the 5‑week period from January 3 to February 6, 2020). The ‘Residential’ category shows a change in duration of time spent at home—the other categories measure a change in total visitors. This index is smoothed to the rolling 7-day average. With the **_Change country_** option in the bottom left corner you can switch to another country. <Chart url="https://ourworldindata.org/grapher/changes-visitors-covid"/> <Callout title="To keep in mind when trying to understand these trends"/> # Retail and recreation This interactive chart shows how the number of visitors to places of retail and recreation has changed compared to baseline days (the median value for the 5‑week period from January 3 to February 6, 2020). This includes places like restaurants, cafes, shopping centers, theme parks, museums, libraries, and movie theaters. This index is smoothed to the rolling 7-day average. <Chart url="https://ourworldindata.org/grapher/change-visitors-retail-recreation"/> <Callout title="Three tips on how to interact with this map"/> # Grocery and pharmacy stores This interactive chart shows how the number of visitors to grocery and pharmacy stores has changed compared to baseline days (the median value for the 5‑week period from January 3 to February 6, 2020). This includes places like grocery markets, food warehouses, farmers markets, specialty food shops, drug stores, and pharmacies. This index is smoothed to the rolling 7-day average. <Chart url="https://ourworldindata.org/grapher/change-visitors-grocery-stores"/> # Public transport stations This interactive chart shows how the number of visitors to transit stations has changed compared to baseline days (the median value for the 5‑week period from January 3 to February 6, 2020). This includes public transport hubs such as subway, bus, and train stations. This index is smoothed to the rolling 7-day average. <Chart url="https://ourworldindata.org/grapher/visitors-transit-covid"/> # Parks and outdoor spaces This interactive chart shows how the number of visitors to parks and outdoor spaces has changed compared to baseline days (the median value for the 5‑week period from January 3 to February 6, 2020). This includes places like local parks, national parks, public beaches, marinas, dog parks, plazas, and public gardens. This index is smoothed to the rolling 7-day average. <Chart url="https://ourworldindata.org/grapher/change-visitors-parks-covid"/> <Callout title="To keep in mind when interpreting this data"/> # Workplace visitors This interactive chart shows how the number of visitors to workplaces has changed compared to baseline days (the median value for the 5‑week period from January 3 to February 6, 2020). This index is smoothed to the rolling 7-day average. <Chart url="https://ourworldindata.org/grapher/workplace-visitors-covid"/> # Time spent at home This interactive chart shows how the number of visitors to residential areas has changed compared to baseline days (the median value for the 5‑week period from January 3 to February 6, 2020). This index is smoothed to the rolling 7-day average. <Chart url="https://ourworldindata.org/grapher/changes-residential-duration-covid"/> <Callout title="To keep in mind when interpreting this data"/> # What effect have these changes had on the spread of the pandemic? ### Explore for yourself in our Coronavirus Data Explorer How have the number of confirmed cases and deaths changed in each country over the course of the pandemic? https://ourworldindata.org/coronavirus-data-explorer Note that Google emphasize: "The Community Mobility Reports were developed to be helpful while adhering to our stringent privacy protocols and protecting people’s privacy.
