The San Antonio area doesn’t divide neatly into young and old neighborhoods, but as residents move through different stages of life, the parts of the city where they cluster tends to shift.
The Express-News dug into recently released U.S. Census Bureau data to map the concentrations of different age groups across the city. The numbers come from surveys conducted between 2020 and 2024, meaning they reflect the ages people were when they answered, not a single-day snapshot of the city.
Because the data is based on surveys collected over time and applied to small areas like ZIP codes, some results can be less precise. Even so, it offers a geographic breakdown of who’s young, who’s old and where each generation calls home.
Here’s how San Antonio’s age groups stack up by ZIP code.
Taken together, the data shows that San Antonio’s age patterns are not evenly distributed. Younger adults tend to cluster around institutions and early-career opportunities, while families and older residents are more common in suburban and outlying areas.
These patterns reflect both how people move through different stages of life and how the region’s housing and development patterns shape where those groups can live. Explore the maps to see how your ZIP code compares.
