Data Note(s)
  • When Births by Mothers Age is selected as the indicator and all ages are selected, the rate displayed is the crude birth rate (i.e., total births divided by total population per 1,000 population).
  • When Births by Mothers Age is selected as the indicator and specific ages are selected, the rate displayed is the age-specific birth rate (i.e., births to mothers in a specific age group divided by females in the same age group expressed per 1,000 population).
  • 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.
  • Use caution when interpreting rates and ratios based on small numbers of events. Rates and ratios are considered unstable if they are based on fewer than 5 cases or if the denominator (population at risk) is fewer than 20. An erratic trend line illustrates this instability.
  • Quartiles are calculated when data is available for at least 51 counties.
  • Population - Rates are calculated using July 1 population estimates from the Florida Legislature, Office of Economic and Demographic Research which have been allocated by race based on information from the US Bureau of the Census. The population data for 2011-2021, along with rates affected by the population data, was updated on FLHealthCHARTS in November 2017. It is customary to periodically revise population estimates based on new information, such as a census or new mid-course census estimates for prior years. Revising these estimates ensures accurate accounting of the racial, ethnic, and gender distribution of the population. These changes affect the population data and rates calculated for your community.
  • These data are only for pregnancies that end with a live birth.
  • 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.
