List of U.S. States and territories by population - wikipedia List of U.S. States and territories by population Population by state, including Puerto Rico ( 2015 ) 580k -- 2.8 M 2.8 M -- 5.28 M 5.28 M -- 8.26 M 8.26 M -- 11.6 M 11.6 M -- 19.6 M 19.6 M -- 26.5 M 26.5 M -- 38.4 M 38.4 M+ As of April 1, 2010, the date of the 2010 United States Census, the nine most populous U.S. states contain slightly more than half of the total population. The 25 least populous states contain less than one - sixth of the total population. California, the most populous state, contains more people than the 21 least populous states combined, and Wyoming is the least populous state, with a population less than the 31 most populous U.S. cities.

Civilian and military federal employees serving abroad and their dependents are counted in their home state. Electoral apportionment Based on data from the decennial census, each state is allocated a proportion of the 435 seats in the United States House of Representatives, although each state is guaranteed a minimum of one seat, regardless of population. This apportionment is based on the proportion of each state 's population to that of the fifty states together ( without regard to the populations of the District of Columbia, AS, GU, MP, PR, or VI ). The Electoral College is the body that, every four years, elects the President and Vice President of the United States. Each state 's representation in the Electoral College is equal to that state 's total number of members in both houses of the United States Congress. The Twenty - third Amendment to the United States Constitution effectively grants the District of Columbia, which is separate from any state, three votes. More precisely, the district gets as many votes in the Electoral College as it would have if it were a state, with the caveat that the district can have no more votes than the least populous state ( which is currently Wyoming ). Currently, this caveat is a moot point since the District of Columbia would only be entitled to one representative if it were a state, and is more populous than only two of the seven states with a single member in the House since 2013. Since the Constitution guarantees every state at least one U.S. Representative and two U.S. Senators, it effectively guarantees every state ( and, since the ratification of the 23rd Amendment, the District of Columbia ) at least three electoral votes. Thus, the total representation in the Electoral College is 538 members ( equal to 100 senators plus 435 representatives, plus 3 members for the District of Columbia ).
