Data item: Resident total population, percent change - April 1, 2000 to April 1, 2010

In Census 2010, people were counted at their "usual residence", a principle followed in each census since 1790. Usual residence has been defined as the place where the person lives and sleeps most of the time. This place is not necessarily the same as the person's voting residence or legal residence.

Noncitizens who are living in the United States are included, regardless of their immigration status.

Persons temporarily away from their usual residence, such as on vacation or on a business trip on Census Day, were counted at their usual residence. People who live at more than one residence during the week, month, or year were counted at the place where they live most of the year. People without a usual residence, however, were counted where they were staying on Census Day.

Scope and Methodology:

Place of residence was derived from answers to questions that were asked of all people in Census 2010 and Census 2000.

The "April 1, 2000 estimates base" reflects corrections to the Census 2000 figures, where necessary, or adjustments to account for any boundary changes subsequent to the census.

Population percent change, 2000 to 2010, is derived by dividing the difference between the population in Census 2010 and the April 1, 2000 estimates base by the April 1, 2000 estimates base.
