Resident population is the population living in the United States.
It includes members of the Armed Forces stationed in the United States and their families. It excludes international military, naval, and diplomatic personnel and their families located here and residing in embassies or similar quarters. Also excluded are international workers and international students in this country and Americans living abroad. The resident population is usually the denominator when calculating birth and death rates, incidence of disease and other rates. Percent distribution is calculated by dividing population in the age group by total resident population.
