List of U.S. states and territories by population

[2] Civilian and military federal employees serving abroad and their dependents are counted in their home state.

[3] Every 10 years, the U.S. Census Bureau is charged with making an actual count of all residents by state and territory.

The accuracy of this count is then tested after the fact, and sometimes statistically significant undercounts or overcounts occur.

[4] Based on this decennial census, each state is allocated a portion of the 435 fixed seats in the United States House of Representatives (until the early 20th century, the apportionment process generally increased the size of the House based on the results of the census until the size of the House was capped by the Reapportionment Act of 1929), with each state guaranteed at least one Representative.

[5] Territories of the United States are not included in the Electoral College: people in those territories cannot vote directly for the President of the United States,[6] although they may participate in the partisan nominating primaries and caucuses.
