Footnotes

a. Annual Population Estimates and Estimated Components of Population Change for the United States and States: April 1, 2000 to July 1, 2008. Source: Population Estimates Program, U.S. Census Bureau. Internet release date: December 22, 2008. Population, population change, and estimated components of population change: April 1, 2000 to July 1, 2008 available at http://www.census.gov/popest/datasets.html.

b. Reported in CDC Water Fluoridation Reporting System (WFRS).

c. Fluoridated population divided by total population.

d. Fluoridated population divided by population served by community water systems.

e. Population served by CWS exceeded the U.S. Census state population estimate; number of persons was reduced by the ratio of the population estimate to the CWS population estimate. Use care in comparing the 2008 estimates for the number of persons receiving fluoridated water and persons served by CWS for these states to estimates from 2002, 2004, and 2006 because a different vintage of U.S. Census population estimates was used. The 2008 vintage was used for the 2008 fluoridation statistics, and the 2006 vintage was used for the 2002, 2004, and 2006 statistics.

f . Complete data were not available from WFRS; state provided additional information.
