Separate statistics are maintained for the five permanently inhabitedterritories of the United States :Puerto Rico ,Guam , theU.S. Virgin Islands ,American Samoa , and theNorthern Mariana Islands .[ 1]
As of April 1, 2020, the date of the2020 United States census , the nine most populousU.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, andWyoming , the least populous state, has a population less than any of the 31most populous U.S. cities .
TheUnited States Census counts the persons residing in theUnited States includingcitizens , non-citizenpermanent residents and non-citizen long-term visitors.[ 2] Civilian and military federal employees serving abroad and their dependents are counted in their home state.[ 3]
Electoral apportionment [ edit ] Every 10 years, theU.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. For example, for the2020 decennial census , 14 states had significant miscounts ranging from 1.5% to 6.6%. While these adjustments may be reflected in government programs over the following decade, the 10-year representative apportionments discussed below are not changed to reflect the miscount.[ 4]
House of Representatives [ edit ] Based on this decennial census, each state is allocated a portion of the 435 fixed seats in theUnited 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 theReapportionment Act of 1929 ), with each state guaranteed at least one Representative. Theallocation is based on each state's proportion of the combined population of thefifty states (not including theDistrict of Columbia ,Guam ,American Samoa , theNorthern Mariana Islands ,Puerto Rico , or theU.S. Virgin Islands ).
TheElectoral College , every four years, elects thePresident andVice President of the United States based on the popular vote in each state and the District of Columbia. Each state's number of votes in the Electoral College is equal to its number of members in the Senate plus members in the House of Representatives.[ 5]
TheTwenty-third Amendment to the United States Constitution additionally grants the District of Columbia (D.C.), which is not a state, as many Electoral College votes as it would have if itwere a state, while having no more votes than the least populous state (Wyoming). Since the U.S. Constitution guarantees every state at least one member of the U.S. House of Representatives and two members of the U.S. Senate, every state has at least three Electoral College votes. Thus, the Electoral College has 538 members (100senators , plus 435 representatives due to the limit imposed by the Reapportionment Act of 1929, plus 3 members for the District of Columbia).[ 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.[ 7]
