Figures are from the World Bank's World Development Indicators (CC BY 4.0), for the newest year most countries have reported; many are estimates, and they are revised as new data comes in. GDP per person is in US dollars at each year's exchange rates, not adjusted for differences in prices. Two figures are called about the same when GDP or population differ by less than 5%, life expectancy by less than a year, or a share by less than 2 percentage points.
