Population Reference Bureau (PRB)’s World Population Data Sheet (WPDS) has been produced annually since 1962 to provide the latest data on key population, health, and environment indicators for the world, major regions, and more than 200 countries and territories. WPDS is a widely-used reference tool for educators, policymakers, advocates, journalists, and others worldwide.

The WPDS features PRB’s latest population projections for 2030 and 2050.  This year’s WPDS focuses on changing age structures around the world.
