About the Florida Birth Atlas     

NOTE: The Atlases on FLHealthCHARTS provide maps, graphs, and some data tables in a dashboard format. This takes more computer resources than other FLHealthCHARTS products. When the Atlases are being accessed by several people at the same time the content may not load you will receive errors. Please return to the Atlases at a later time when you experience this issue.

The Florida Birth Atlas provides a written analysis and graphic display of fertility trends in Florida over the past quarter century. There are several maps, charts and graphs, used to illustrate demographic trends from 1989 to 2016, by age, race, and ethnicity.
Unknown values of birth are not included in graphs. Due to this, the data displayed in each graphic is only for total known records.
