Mapping Austin ZIP codes by age: Some neighborhoods may surprise you

Stroll through West Campus on any given Tuesday afternoon — or Saturday at 2 a.m. — and it's obvious: ZIP codes 78705 and 78712 are the epicenter for Austinites ages 18 to 21. Most age groups, however, aren't so densely clustered.

We mapped age groups across Austin, using U.S. Census Bureau data, for a geographic breakdown of where each generation calls home.

As expected, college-age residents are concentrated around UT and the urban core, while families with children and many older adults are more common in suburban and outer ZIP codes.

The maps reflect broader housing patterns of where people live at different stages of life. Explore below to see how your ZIP code compares.

About the data: The data 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. The data is based on surveys collected over time and applied to small areas like ZIP codes, so some results can be less precise.
