Note: The growth rate may not equal the sum of the rate of natural increase and the migration rate due to rounding.
Note: Births, deaths, and net number of migrants are approximated as their respective rates times the midyear population and may not add to totals due to rounding.
United States data are based on official estimates and projections. All population estimates and projections are for the resident population. Population estimates for 2000-2012 are consistent with the 2010 Census. Population data in the IDB for 2013-2050 are based on the 2012 National Projections, Middle Series. The U.S. population components shown in the IDB for 2000-2050 may not match the official population components for the United States, due to differences in how they are displayed (calendar year versus midyear-to-midyear estimates). Revised official population estimates are released each year (www.census.gov/popest). Therefore, the U.S. population estimates (official compared with IDB) may not match due to differences in the timing of their release.
