2011 Monthly National Population Estimates

The Population Estimates Program produces monthly population estimates by age, sex, race, and Hispanic origin for the United States. These estimates cover four different populations: resident population, resident population plus Armed Forces overseas, civilian population, and civilian noninstitutionalized population. All reference dates in the monthly national estimates refer to the first of the month.
