Written by becomes the World Inequality Database

In March 2018, the name of was changed from the World Wealth and Income Database to the World Inequality Database. This was motivated by two reasons.

First, this change allows us to harmonize the name of the database, the name of the Lab which administers it (the World Inequality Lab) and the name of the flagship publication stemming from the database (the World Inequality Report). We believe that this consistency will make it easier for users to cite the database–as we noticed that there were several confusions in the past.

Second, this new name is in line with the mid to long-term objective of the database. While the database remains essentially centered on income and wealth inequality series, we seek to progressively expand the scope of the database with more data related to other dimensions of social inequality (gender, environment, politics, etc.).
