Young population shaped by the military base
Jacksonville has one of the youngest populations in the United States due to Marines and their families. The median age is around 23, with high turnover.
The city's demographics are atypical for the rural South. The massive presence of active-duty military and dependents keeps the median age very low, with young families who typically stay two to four years before being reassigned to other bases. This results in neighborhoods that are constantly renewing.
Most residents identify as white, followed by a significant African American population and residents who identify as Hispanic or Latino. Filipino, Mexican, and Central American communities have grown around the base, tied to marriages with service members and support services.
English is the dominant language, but Spanish and Tagalog appear in markets, churches, and schools. Christianity, particularly in Baptist and Methodist traditions, dominates religious life, with Catholic churches and Pentecostal congregations also present.
