United States Census

The United States Census is one in the United States of America since 1790 every ten -yearly census, as required by the Constitution of the United States. It is carried out by the United States Census Bureau.

History

The Constitution of the United States on September 17, 1787, provides in Article 1, paragraph 2 a decennial Census ago. At that time included the thirteen States about 2.5 million people.

Originally, since 1600, emerged censuses in Virginia, by the inhabitants were counted in almost all British colonies.

Over time, the aspects studied were more complex. For example 1840, industries such as the fishery were examined, as well as the social, religious and tax points were expanded. There is also a geographical division. A more detailed list of points examined will be found in each of the major articles:

  • 09 United States Census 1870
  • 10 United States Census 1880
  • 11 United States Census 1890
  • 12 United States Census 1900
  • 13 United States Census 1910
  • 14 United States Census 1920
  • 15 United States Census 1930
  • 16 United States Census 1940

Data collection

Although in the United States no obligation of residence exists, the U.S. citizenship of the population is provided with data collection always. As a general rule all persons recorded live over a longer period in the country. It also does not matter whether they live in the country legally or illegally. This is problematic insofar as that used to form the House of Representatives numbers do not represent exactly the actual electorate in elections. Especially the southern states with their increased share of immigrants are represented as only approximate.

The lack of mandatory reporting further results that the number of households is always stated in their absolute number, while used as a second home households are not included in the calculation of persons per household. This in turn leads primarily in the southern part to a non-representative ratio of population to the number of households.
