2004 Water Fluoridation Statistics
These statistics were prepared using water system data reported by states to
the CDC Water Fluoridation Reporting System as of December 31, 2004, and the
U.S. Census Bureau population estimates.
Some estimates previously reported for 2004 have been revised due to
corrections of errors in reporting or rounding, or application of the
methodology for the 2006 fluoridation statistics as reported in Bailey W,
Duchon K, Barker L, Maas W. Populations
receiving optimally fluoridated public drinking water – United States,
1992–2006. MMWR 2008; 57(27):737–741.

Footnotes
a. Annual Population Estimates and Estimated Components of Population
Change for the United States and States: April 1, 2000 to July 1, 2006.
Source: Population Estimates Program, U.S. Bureau of the Census. Internet
release date: December, 22, 2006. Population, population change, and
estimated components of population change: April 1, 2000 to July 1, 2006

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 community water systems (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 caution 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.
f . Complete data were not available from WFRS; state provided additional
information.
