District of Columbia in the context of "Comcast"

The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and minor islands. Both the states and the United States as a whole are each sovereign jurisdictions. The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government. All states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state elects two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census.

Each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge two or more states into one without the consent of all states involved. Each new state is admitted on an equal footing with the existing states.

A minor civil division (MCD) is a term used by the United States Census Bureau for primary governmental and/or administrative divisions of a county or county-equivalent, typically a municipal government such as a city, town, or civil township. MCDs are used for statistical purposes by the Census Bureau, and do not necessarily represent the primary form of local government. They range from non-governing geographical survey areas to municipalities with weak or strong powers of self-government. Some states with large unincorporated areas give substantial powers to counties; others have smaller or larger incorporated entities with governmental powers that are smaller than the MCD level chosen by the Census.

As of 2010, MCDs exist in 29 states, the District of Columbia, and Puerto Rico. In all other states where state-defined entities are not used for census purposes (mostly in the South and the West), the Census Bureau designates Census County Divisions (CCDs). For several decennial censuses prior to the 2010 census, 28 states used MCDs, but in 2008, Tennessee changed from CCDs to MCDs, bringing the total number of MCD states to 29.

The contiguous United States, also known as the U.S. mainland, officially referred to as the conterminous United States, consists of the 48 adjoining U.S. states and the District of Columbia of the United States in central North America. The term excludes the only two non-contiguous states and the last two to be admitted to the Union, which are Alaska and Hawaii, and all other offshore insular areas, such as the U.S. territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. The colloquial term Lower 48 is also used, especially in relation to Alaska. The term The Mainland is used in Hawaii. The related but distinct term continental United States includes Alaska, which is also in North America, but separated from the 48 states by British Columbia in Canada, but excludes Hawaii and all the insular areas in the Caribbean and the Pacific.

The greatest distance on a great-circle route entirely within the contiguous U.S. is 2,802 miles (4,509 km), coast-to-coast between Florida and Washington state; the greatest north–south line is 1,650 miles (2,660 km). The contiguous United States occupies an area of 3,119,884.69 square miles (8,080,464.3 km). Of this area, 2,959,064.44 square miles (7,663,941.7 km) is actual land, composing 83.65 percent of the country's total land area, and is comparable in size to the area of Australia. Officially, 160,820.25 square miles (416,522.5 km) of the contiguous United States is water area, composing 62.66 percent of the nation's total water area.

In 45 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 Connecticut, Massachusetts, and Rhode Island, 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.

There are 41 independent cities in the United States. In Virginia, any municipality that is incorporated as a city legally becomes independent of any county. Where indicated, the statistics below do not include Virginia's 38 independent cities.

This is a list of the 50 states, the 5 territories, and the District of Columbia of the United States of America by population density, population size, and land area. It also includes a sortable table of density by states, territories, divisions, and regions by population rank and land area, and a sortable table for density by states, divisions, regions, and territories in square miles and square kilometers.

The population density of the United States is lower than that of many other countries because of the United States' large land area. There are large, sparsely populated areas in parts of the US, like the east-to-west stretch extending from Minneapolis to the outskirts of Seattle, or the north-to-south portion from northern Montana to southern New Mexico, excluding Denver and Albuquerque. For comparison, the population density of the U.S. is 1/15 that of South Korea and 1/12 that of India and the Netherlands. On the other hand, it is over 8 times higher than that of Canada and over 9 times higher than that of Australia.

District of Columbia home rule is the District of Columbia residents' ability to govern their local affairs. The District is the federal capital; as such, the Constitution grants the United States Congress exclusive jurisdiction over the District in "all cases whatsoever".

Before 1874 and since 1973, Congress has allowed certain powers of government to be carried out by locally elected officials. However, Congress maintains the power to overturn local laws and exercises greater oversight of the district than exists for any U.S. state. Furthermore, the District's elected government exists under the grace of Congress and could theoretically be revoked at any time.

The District of Columbia retrocession was the act of returning to Virginia some of the land from the District of Columbia that Virginia had previously ceded to the federal government of the United States. The land was originally ceded to the federal government by Virginia and Maryland in 1790 for the purpose of creating a federal district for the new national capital; the capital was moved from Philadelphia to what was then called the City of Washington in 1800. After moving through various stages of federal and state approval, the Virginia portion was retroceded in March 1847.

Retrocession is the act of returning some or all of a portion of land that had previously been ceded.

The District of Columbia Organic Act of 1871 is an Act of Congress that repealed the individual charters of the cities of Washington and Georgetown and established a new territorial government for the whole District of Columbia. Though Congress repealed the territorial government in 1874, the legislation was the first to create a single municipal government for the federal district. Direct rule by Congress continued until the 1973 passage of the District of Columbia Home Rule Act, a century later.
