Data Sources
A description of the empirical data used and the methods applied in revising past estimates of population and components of demographic change (fertility, child, adult and overall mortality, international migration) is available here for each country or area for the period 1950-2020. Additional analytics and codified metadata will also be posted by July 2019. For the countries with less than 90,000 inhabitants in 2019, only the data sources for total population are made available.
