Median age divides the age distribution into two equal parts: one-half are below the median age and one-half are above the median.
Age data are needed to interpret social and economic characteristics used to plan and examine many public health programs and policies.
In 2021, Population Median Age (Census) in Alachua County was 32.1 compared to Florida at 42.3. The line graph shows change over time when there are at least three years of data.
Alachua County is in the first quartile for this measure. This means that relative to other counties in Florida, the situation occurs more often in about three quarters of the counties. The map illustrates county data by quartile. When fewer than 51 counties have data or zero values, no quartile map will be presented.

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.
