Sources, dates and method

World Bank World Development Indicators, drawing on UN World Population Prospects and national statistical sources. Demographic values are annual estimates. Each indicator retains its own year; missing values are not replaced with zero.

These data put generations in demographic context. They do not replace named censuses or records for proving identity or relationships. Historical series follow the source’s geographical scope, not necessarily each period’s borders.
