Data Source: FLHealthCHARTS Interactive Mapper data is provided by the Florida Department of Health Bureau of Vital Statistics and the 2015 American Community Survey 5-year estimates (tables B02001, B03002, S0101, S1501, S1701, S1903, S2301, S2506, S2701)
Census tracts are the preferred unit of analysis compared to zip
codes. They are designed to have a homogenous population with an average of 4,000
people. The tracts are established as consistent blocks of geography that
remain stable over a 10-year period. Every decennial, the U.S. Census Bureau updates
census tract boundaries to coincide with the updated population figures. Data
in the FLHealthCHARTS Interactive Mapper uses 2010 census tract boundaries.
Zip codes are created for use by the U.S. Postal Service for mail
delivery purposes. The boundaries of a zip code may not be based on population
characteristics. The population contained within zip codes is not the same for
every zip code. Additionally, the zip code numbering system is constantly
changing to facilitate the delivery of mail. Zip codes may span over county
boundaries. In the FLHealthCHARTS Interactive Mapper, zip codes that include
areas in more than one county will report just the count or rate from the
Use caution when interpreting rates based on small numbers of events.
Rates are considered unstable if they are based on fewer
than 5 events or if the denominator (population at risk) is fewer than 20.
Quartiles are calculated by ranking counties or subcounty regions in order of most favorable (Quartile 1) to least favorable (Quartile 4). These groups are divided into four parts with Quartile 1 being the top 25% and Quartile 4 being the lowest 25%.
The term ‘Births’ refers to Resident Live Births.
