Population Estimates | Population Projections

The U.S. Census Bureau uses birth data from NCHS and from state departments of vital statistics in our population estimates and projections programs. The data presented in these products have been modified by our estimates and projections procedures and therefore will differ from the annual births released in NCHS products.
