Our World in Data presents the empirical evidence on global development in entries dedicated to specific topics. In this blog post we cover the link between globalization and inequality. In two separate companion posts we cover [the link between globalization and economic growth](https://owid.cloud/trade-and-econ-growth) , and [the link between globalization and jobs](https://owid.cloud/trade-wages-cost-living) . These articles draw on data and research discussed in our entry on **[International Trade](https://ourworldindata.org/international-trade)** . Over the last couple of years several studies have found that trade has a negative impact on earnings and employment for some groups of people. This fact, which I discuss in a [companion blog post,](https://owid.cloud/trade-wages-cost-living) is usually interpreted as evidence that trade is a major driver of income inequality.
