Who's Counted

The apportionment calculation is based upon the total resident population (citizens and noncitizens) of the 50 states. In the 2010 Census, the apportionment population also includes U.S. Armed Forces personnel and federal civilian employees stationed outside the United States (and their dependents living with them) that can be allocated back to a home state. These segments were also included in the apportionment population in the 1970, 1990, and 2000 censuses. The population of the District of Columbia is not included in the apportionment population.
