Sources & methodology
This profile uses United Nations World Population Prospects 2024 as the primary framework for globally comparable population, age, fertility and projection data. The World Bank is the primary source for the female population share. Some country values were accessed through secondary retrieval interfaces that republish or organize UN data; those interfaces are identified below as secondary and are not treated as the original statistical publishers.
