The U.S. Census Bureau has been preparing estimates and projections of the populations of foreign countries since the 1960s.  In the 1980s, the Census Bureau released its first comprehensive set of estimates and projections for over 200 countries and areas of the world.  Since then, the Census Bureau periodically updates estimates and projections for countries as new data become available and funding permits.  Estimates and projections exist for the countries and areas recognized by the U.S. Department of State which have populations of 5,000 or more.  Population size (by single year of age and sex) and components of change (fertility, mortality, and migration) are provided for each calendar year beyond the initial or base year, through 2050.
