How many square miles is Montana

Population density in the USA

Preliminary remark:

Area data for large countries with complicated geography are not without problems. The United Nations put the area of ​​the USA at 9,363,520 km². According to the 2001 CIA World Factbook, however, the total area is 9,629,091 km². The Fischer Weltalmanach 2002 gives the area including inland waters with 9,809,155 km². According to the U.S. Census Bureau total land and water area is 3,794,083 square miles (square miles). For a land mile of 1.6093472 km and a square mile of approx. 2.59 km² in the USA, roughly the same value is calculated as the value given in the Fischer World Almanac, which is adopted in the following - as well as the area data for the individual states becomes.

Incidentally, the water areas in the USA alone are almost twice as large as the whole of Germany, at 256,645 square miles. The pure land area remains 3,537,438 square miles = about 9,161,960 km & sup2.

The so-called Nighttime Map of the U.S. Census Bureau, where the distribution of the US population is shown in small white dots on the dark background of the American land area, creating the illusion of a nocturnal satellite image. Each point represents 7500 people.

The following table shows the population distribution in a large-scale breakdown with number of inhabitants, areas and population density.

The 50 states and the District of Columbia are regionally assigned as follows:

  • New England: Maine, New Hampshire, Vermont, Massachusetts, Rhode Islands, Connecticut
  • Middle Atlantic: New York, New Jersey, Pennsylvania
  • East North Central: Ohio, Indiana, Illinois, Michigan, Wisconsin
  • West North Central: Minnesota, Iowa, Missouri, North Dakota, South Dakota, Nebraska, Kansas
  • South Atlantic: Delaware, Maryland, District of Columbia, (practically the federal capital Washington), Virginia, West Virginia, North Carolina, South Carolina, Georgia, Florida
  • East South Central: Kentucky, Tennesee, Alabama, Mississippi
  • West South Central: Arkansas, Lousiana, Oklahoma, Texas
  • Mountain: Montana, Idaho, Wyoming, Colorado, New Mexico, Arizona, Utah, Nevada
  • Pacific: Washington, Oregon, California, Alaska, Hawaii

The Hawaiian Islands in the Pacific, like Alaska, which is located on the North American mainland and separated from the rest of the USA by Canadian territory, are among the 50 "United S.tates of A.merica ".

In contrast, the small District of Columbia (D.C.) is not a state.
"Columbia" is an early, rather poetic name for the USA, derived from the name of the discoverer Columbus.
The District of Columbia was formed in 1791 from land ceded by the states of Maryland and Virginia to build a new federal capital in a 10 by 10 mile square on either side of the Potomac River (about 16 by 16 square kilometers). In 1800 Washington D.C. (after New York and Philadelphia) permanent capital. With the city growing more slowly than expected, the area to the right of the bank was returned to Virginia in 1846.
But it was there, of all places, that the largest building in the world was built later: the Pentagon, with a Washington address, but on the ground in Virginia.

For the structure of the USA see also graphics card.

If you factor out the American state of Alaska and the Rocky Mountains area (approx. 40% of the area), you get 45 inhabitants per square kilometer, which is the world average. If one assumes the total area of ​​the USA minus the inland waters (see above), the population density is 31 inh. / Km² (instead of 29).

Like the nightime map, the table also shows the northeast as the most densely populated region. If you go by the states of this region less of the extreme north with the sparsely populated New England states of Maine, Vermont and New Hampshire and instead calculates the south-Atlantic states of Delaware and Maryland as well as the District of Columbia added, you get an ideal area for a size comparison with Germany.

In the American comparison area (which forms an approximate semicircle around New York City) about 20% of all residents of the USA live on 4% of the country's area. Therefore, the population density there is about five times the US average. However, the roughly 57 million inhabitants there are compared to around 82 million inhabitants in Germany on roughly the same area.

Thus, the average density in the American comparison area is only about 2/3 as high as the population density in Germany - or vice versa:
the Federal Republic is almost 1.5 times as densely populated as the exceptional region on the American east coast.

(According to a list by Demographia, the metropolitan area around New York City ranks second with Large International Urban Areas / 2001 in terms of population in a global comparison: Urban Area New York 17.8 million inhabitants / 8,684 km² / 2,050 Inhabitants per km².)

To supplement a few economic data:

According to the Bureau of Economic Analysis (BEA) on Gross State Product, it can be calculated that the comparison area had a share of around 23.6% of total American GDP in 2001, namely 2,391,130 million from 10,137,190 million . current dollars (published on May 22, 2003). Using these figures, a corresponding value in international dollars can be calculated for the east coast region, the unit in which the World Bank specifies GDP according to purchasing power parity: around 2,310,000 million (of 9,792,473 million) international dollars. Converted to square kilometers, this equates to almost 6.3 million international dollars.

For comparison Germany: 2,086,828 million international $ in total and a good 5.8 million international $. per square kilometer, so a similarly high value. (For the GDP per capita there is of course a larger gap due to the different population figures.)

The area around New York is so extraordinary and internationally significant that it might be worth making a second comparison. In addition, the area is much more narrowly limited to the states of Massachusetts, Rhode Island, Connecticut and New Jersey and (exceptionally below the state level) to the southeastern part of the state of New York with the area of ​​Mid-Hudson, which is wedge-shaped between Connecticut and New Jersey pushes, as well as New York City and Long Island.

Mid-Hudson is made up of the counties Sullivan, Ulster, Dutchess, Orange, Putnam, Rockland and Westchester. New York City is divided into the Bronx, New York, Richmond, Kings and Queens. Long Island includes Nassau and Suffolk. A clickable map of Fedstats leads to population and area information (in square miles) for the 14 named counties within the state of New York. - (See also New York State website with interactive map.)

Comparison area 2 in USA (2001) 32.340 million83.967385

In this area on the east coast, 11.4% of the US population live on 0.9% of the land area. If we compare this region with an area in western Germany cut to roughly the same size, we surprisingly come across a very similar population and population density:

 ResidentsArea (km²)E. per km²
North Rhine-Westphalia18.010 million34.081528
Hesse6.068 million21.114287
Rhineland-Palatinate4.035 million19.847203
Saarland1.069 million2.569416
Karlsruhe administrative district (BW)2.684 million6.919388
 together (Late 2000)31.866 million84.530377

In both cases, around 32 million people live in roughly the same area, more than in huge Canada. This should give food for thought, especially since the German area within the national territory does not have the exceptional character of the American one, because that too rest Germany (with around 50 million inhabitants) has a high population density of 185 inhabitants per square kilometer, about six times as high as the overall average in the USA.

The most densely populated US state is New Jersey (see above), although the immediately neighboring New York City has almost the same population on a small fraction of the area.

Largest, d. H. The most populous state in the USA is California (34.501 million inh. / 424,002 km² / 81 inh. per km²) on the Pacific coast. The large metropolitan areas around Los Angeles and San Francisco, in which the majority of the Californian population lives, can be easily recognized on the aforementioned Nighttime Map.

The largest US state in terms of area is Alaska, which is included in the first table, with a population like Frankfurt am Main and an area that is almost five times the size of Germany. The population density there is less than 0.4 inhabitants per square kilometer.

In the CIA's World Factbook, Germany is compared to a federal state in the west on the Canadian border. According to this, Germany is "slightly smaller than Montana" - (in terms of area).

Here is a size comparison of the most populous US states to California (As of mid-2001) with the most populous German federal state. The differences in area and population density with a similarly high population speak for themselves.

By selecting a state on a US map from FedStats (and then clicking on ‘view map’) a map is available for each state. There are also thematic maps on various topics, including persons per square mile.

Information about all US states can also be found under 50 States (including the state songs - e.g. with familiar sounds from Michigan, Iowa and Maryland) and under States (e.g. on the origin of state names).

The USA, which is rather sparsely populated compared to Germany, still has to reckon with strong population growth - as in the last few decades. Between the 1990 and 2000 censuses alone, the US population grew by 13.2%. The growth of 32.7 million people in just ten years (through natural offspring and immigration) is greater than the entire population of the G7 nation Canada today.

On the subject of immigration, see also: Immigration and Naturalization Service.

In the World Population Prospects, 2002 revision, the United Nations anticipates a further increase to over 408 million inhabitants by 2050. See also population development in the USA. (The average population density would then still be very low compared to Germany.) From mid-2000 to mid-2001, according to the Census Bureau, the population of the USA increased from 282.125 million to 284.797 million, i.e. by 2.672 million more than 0.9%.

But not a few US citizens are concerned about the rapid growth. The Federation for American Immigration Reform: FAIR ( recognizes the historical role of immigration in the construction of America, but deplores today's mass immigration and advocates a fundamental new regulation and reduction of immigration: "The Federation for American Immigration Reform (FAIR) is a national, non-profit, public-interest, membership organization of concerned citizens who share a common belief that the unforeseen mass immigration that has occurred over the last 30 years should be curtailed. "

"Negative Population Growth": NPG (, an association founded in 1972 and now with 25,000 members, also aims to reduce the American population to around 150 million people through a lower birth rate: "Only with a much smaller population can we protect our fragile ecosystems, conserve our finite resources, and ensure that future generations will inherit a clean and healthy environment where all Americans can enjoy a quality standard of living. "

Countries with a low fertility rate like Germany are apparently based on NPG: "The US average fertility rate is currently 2.1335 births per woman, the US's highest fertility rate since 1971. (For comparison, the United Kingdom's fertility rate is 1.7, Canada's is 1.4 , and Germany's is 1.3.) "

Finally, a few links on the traces of German immigrants, whose descendants - despite today's predominant immigration from Latin America and Asia - still form the largest ancestry group in the USA.
