Population Receiving Fluoridated Water

Definition:
A community water supply system provides water to the public for human consumption through pipes or other constructed conveyances and serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents (as defined by Florida's Department of Environmental Protection). This indicator estimates the population served by a community water system that has adjusted their water with fluoride, has fluoride naturally occurring in their water, or purchases water from another system which is adjusted or naturally fluoridated to be considered a fluoridated system.

Why do we measure this?
Water fluoridation is the controlled addition of fluoride to a public water supply in order to reduce tooth decay. Moderate water fluoridation prevents tooth decay and is now reaching about two-thirds of the US population on public water systems. Tooth decay (dental caries) is one of the most prevalent chronic diseases worldwide and one which greatly affects the quality of life of children, particularly those of low socioeconomic status. Fluoride toothpaste, dental sealants and other techniques are also effective in preventing tooth decay. Water fluoridation, when technically feasible, has substantial advantages over toothpaste, especially for those at high risk.

Data Note(s)
  • A community water system serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents.
  • All of the population served counts are determined by the Florida Department of Environmental Protection and provided to the PHDP on an annual basis at the water system level.
  • In order for a community water system to be considered as fluoridated water, it must fall into one of the following categories for at least one month of the calendar year: 1. Adjusted (supplements water with fluoride) 2. Naturally fluoridated (fluoride levels naturally occurring in water) 3. Consecutive (buys water from an adjusted, natural fluoridated or fluoridated consecutive water system)
  • Numerator: Number of people on community water systems receiving fluoridated water. Denominator: Number of people on community water systems.
  • The methodology of this measurement may have changed over time, specifically from 2013 forward.
  • Chart will display if there are at least three years of data.
  • Multi-year counts are a sum of the selected years, not an average.
  • Quartiles are calculated when data is available for at least 51 counties.
  • MOV - Measure of Variability: Probable range of values resulting from random fluctuations in the number of events. Not calculated when numerator is below 5 or denominator is below 20, or count or rate is suppressed. The MOV is useful for comparing rates to a goal or standard. For example, if the absolute difference between the county rate and the statewide rate is less than the MOV, the county rate is not significantly different from the statewide rate (alpha level = 0.05). When the absolute difference between the county rate and the statewide rate is greater than the MOV, the county rate is significantly different from the statewide rate. MOV should not be used to determine if the rates of two different counties, or the county rates for two different years, are statistically significantly different.
  • Denom - abbreviated for Denominator.
  • Population estimates are not available for persons whose county of residence is unknown. Given this, the denominator and associated rate are not available.
  • * - Indicates the county rate is statistically significantly different from the statewide rate.
