The states and territories included in the United States Census Bureau's statistics include the fifty states, the District of Columbia and five permanently inhabited unincorporated island territories, including Puerto Rico.
As of April 1, 2010, the date of the 2010 United States Census, the 9 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, the least populous state, has a population less than each of the 31 most populous U.S. cities.
The United States Census counts total persons residing in the United States including citizens, non-citizen permanent residents, and non-citizen long-term visitors.Civilian and military federal employees serving abroad and their dependents are counted in their home state.
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, Guam, American Samoa, the Northern Mariana Islands, Puerto Rico, or the United States Virgin Islands). 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 member of the House of Representatives 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).

The Twenty-third Amendment to the United States Constitution extends the right to vote in presidential elections to citizens residing in the District of Columbia. The amendment grants the district electors in the Electoral College as though it were a state, though the district can never have more electors than the least-populous state. The Twenty-third amendment was proposed by the 86th Congress on June 16, 1960, and was ratified by the requisite number of states on March 29, 1961.
The Electoral College is a body of electors established by the United States Constitution, constituted every four years for the sole purpose of electing the president and vice president of the United States. The Electoral College consists of 538 electors, and an absolute majority of 270 electoral votes is required to win election. According to Article II, Section 1, Clause 2 of the Constitution, each state legislature determines the manner by which its state's electors are chosen. Each state's number of electors is equal to the combined total of the state's membership in the Senate and House of Representatives; currently there are 100 senators and 435 representatives. Additionally, the Twenty-third Amendment, ratified in 1961, provides that the District of Columbia (D.C.) is entitled to the number of electors it would have if it were a state, but no more than the least populated state. U.S. territories are not entitled to any electors as they are not states.
In the United States, a county is an administrative or political subdivision of a state that consists of a geographic region with specific boundaries and usually some level of governmental authority. The term "county" is used in 48 U.S. states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively.
Columbia County is a county located in the U.S. state of Pennsylvania. As of the 2010 census, the population was 67,295. Its county seat is Bloomsburg. The county was created on March 22, 1813, from part of Northumberland County and named for Columbia, a poetic name for the United States that alludes to Christopher Columbus.
In 48 of the 50 states of the United States, the county is used for the level of local government immediately below the state itself. Louisiana uses parishes, and Alaska uses boroughs. In several states in New England, some or all counties within states have no governments of their own; the counties continue to exist as legal entities, however, and are used by states for some administrative functions and by the United States Census bureau for statistical analysis. There are 3,242 counties and county equivalent administrative units in total, including the District of Columbia and 100 county-equivalents in the U.S. territories.
United States congressional apportionment is the process by which seats in the United States House of Representatives are distributed among the 50 states according to the most recent decennial census mandated by the United States Constitution. Each state is apportioned a number of seats which approximately corresponds to its share of the aggregate population of the 50 states. However, every state is constitutionally guaranteed at least one seat.
The District of Columbia Voting Rights Amendment was a proposed amendment to the United States Constitution that would have given the District of Columbia full representation in the United States Congress, full representation in the Electoral College system, and full participation in the process by which the Constitution is amended. It would have also repealed the Twenty-third Amendment, which granted the District of Columbia the same number of electoral votes as that of the least populous state, but gave it no role in contingent elections.
Apportionment is the process by which seats in a legislative body are distributed among administrative divisions entitled to representation.
The Graduated Random Presidential Primary System, also known as the California Plan or the American Plan, is a proposed system to reform the conduct of United States Presidential primary campaigns. Under this system the campaign period would be broken into ten two-week periods in which an escalating number of electoral votes would be contested. It was developed by aerospace engineer and political scientist Thomas Gangale in 2003 in response to the trend toward front-loading in recent primary campaigns and the influence wielded by Iowa and New Hampshire, which traditionally hold their nominating events before any other state.
