Census 2000 - State Population and Apportionment Data

The fundamental reason for conducting the decennial census of the United States is to apportion the members of the House of Representatives among the 50 states. A state's resident population consists of those persons "usually resident" in that state (where they live and sleep most of the time). A state's apportionment population is the sum of its resident population and a count of overseas U.S. military and federal civilian employees (and their dependents living with them) allocated to the state, as reported by the employing federal agencies. Based on the Census 2000 apportionment, each member of the U.S. House of Representatives represents an average population of 646,952.
