The Census Bureau cannot go out and count every man, woman and child each year. Instead, it uses statistical models and a multitude of data sources to estimate the nation's population down to the smallest geography. The data here is sorted in descending order by the overall population change from 2000 to 2006. Click on any column heading to re-sort the data in ascending or descending order.

The U.S. Census Bureau produces annual population estimates for the Nation, the States, the District of Columbia, counties and equivalents, incorporated places, minor civil divisions, consolidated cities, census regions and divisions, and metropolitan areas.

You can enter a city or county name for a quick search. Or select a state from the drop-down menu and click search to see all data for a given state.

Violent crime increased 1.3 percent nationwide while property crime fell by 2.9 percent in 2006, according to the FBI's Uniform Crime Reporting (UCR) program. The agency annually releases statistics on violent crimes like murder, rape and robbery and on property crimes such as burglary and vehicle theft. Not all agencies participate in the UCR program and therefore are not reflected in the data.
