Global average GDP per capita over the long run

In constant international-$

These historical estimates of GDP per capita are adjusted for inflation. We combine three sources to create this time series: the Maddison Database (before 1820), the Maddison Project Database (1820–1989), and the World Bank (1990 onward). This data is expressed in international-$ at 2021 prices.
