On Tuesday, Dec. 21, the U.S. Census Bureau announced that the 2010 Census showed the resident population of the United States on April 1, 2010, was 308,745,538. This was an increase of 9.7 percent over the 2000 U.S. resident population of 281,421,906. Of that 27,323,632 total resident increase, Iowa grew by 120,031 residents. The Iowa population grew by 4.1% since the 2000 census was taken, growing from 2,926,324 to 3,046,355. This the first time that Iowa's population has been over the 3 million mark.

The U.S. resident population represents the total number of people in the 50 states and the District of Columbia. The most populous state was California (37,253,956); the least populous, Wyoming (563,626). The state that gained the most numerically since the 2000 Census was Texas (up 4,293,741 to 25,145,561) and the state that gained the most as a percentage of its 2000 Census count was Nevada (up 35.1% to 2,700,551).

Regionally, the South and the West picked up the bulk of the population increase, 14,318,924 and 8,747,621, respectively. But the Northeast and the Midwest also grew: 1,722,862 and 2,534,225. Additionally, Puerto Rico's resident population was 3,725,789, a 2.2 percent decrease over the number counted a decade earlier.

The first census was in 1790, little more than a year after the inauguration of President Washington. The Congress assigned responsibility for the 1790 census to the marshals of the U.S. judicial districts under an act that, with minor modifications and extensions, governed census-taking through1840. The law required that every household be visited and that completed census schedules be posted in ''two of the most public places within [each jurisdiction], there to remain for the inspection of all concerned...'' and that "the aggregate amount of each description of persons'' for every district be transmitted to the President. The six inquiries in 1790 called for the name of the head of the family and the number of persons in each household of the following descriptions: Free White males of 16 years and upward (to assess the country's industrial and military potential), free White males under 16 years, free White females, all other free persons (by sex and color), and slaves. In that first census, the population of the United States was just under 4 million people.

Iowa became a state in 1846 and began showing up before that in the 1840 census.

Additional state and county census data will be rolling out during 2011.

Finally, why do we have a census taken every 10 years? Article I, Section 2 of the U.S. Constitution calls for a census of the nation's population every 10 years to apportion the US House of Representative seats among the states. The 2010 Census was the 23rd census in our nation's history.
