Water Fluoridation Data & Statistics
The number of communities and people who benefit from water fluoridation is continuing to increase. This safe, healthy, and effective public health intervention was initiated in 1945. In 2012, 74.6% of the U.S. population on public water systems, or a total of 210,655,401 people, had access to fluoridated water.
CDC monitors the progress of the United States and individual states toward meeting the Healthy People 2020 objective on community water fluoridation—that 79.6% of people on public water systems will receive water that has the optimum level of fluoride recommended for preventing tooth decay.
Water Fluoridation Reporting System (WFRS)
WFRS is a water fluoridation monitoring data system for state and tribal water fluoridation program managers and oral health program directors or managers. Data from WFRS are summarized in the biennial report of national and state fluoridation statistics.
National Oral Health Surveillance System (NOHSS)
NOHSS provides national and state statistics on water fluoridation for 1992, 2000, 2002, 2004, and 2006. This information is available in tables, graphs, maps, and state profiles. Long-term trends in national water fluoridation statistics are also presented in a graph and table.
Synopses of State and Territorial Dental Public Health Programs (Synopses)
Synopses presents biennially reported water fluoridation statistics in the context of annually reported state oral health program information. Footnotes specify the time period and data source for water fluoridation and other state program statistics presented in the Synopses.
Oral Health Maps
This resource provides national and state fluoridation statistics for 1992, 2000, 2002, 2004, and 2006. It also generates state and county fluoridation statistics from the most current data available in the Water Fluoridation Reporting System (WFRS) for the states that have approved this use of their WFRS data.
Calculating Fluoridation Statistics
This fact sheet describes the methodology used by state drinking water programs, EPA, and CDC to estimate the number of people served by water systems, the number of people receiving fluoridated water, and the Healthy People objective for water fluoridation.
