Note: The April 1, 2000 estimates base reflects changes to the Census 2000 population resulting from legal boundary updates as of January 1, 2007, other geographic program changes, and the Count Question Resolution program.
All geographic boundaries for the July 1, 2007 population estimates series are as of January 1, 2007.
The Office of Management and Budget's statistical area definitions (for metropolitan statistical areas) are those issued by that agency in December 2006.
The metropolitan statistical area population estimates are based upon the county estimates.
The county estimates methodology is available at: <http://www.census.gov/popest/topics/methodology/2007-st-co-meth.pdf>.
Total population change includes residual (see http://www.census.gov/popest/topics/terms/states.html); i.e. total population change is equal to natural increase + net migration + the residual.
