Between 2010 and 2020, Austin gained more residents than almost any other city in the US, only falling behind New York City, Houston, and Fort Worth. Talk about big changes.

To better understand what that growth means for our city’s demographics, the City of Austin released a report last week on changes to the population of Austinites in the last decade. Read on for five takeaways.

Austin’s population is getting older.

People aged 65+ are the fastest-growing age group in ATX, increasing from 7% of the population to 9.5% between 2010 and 2020. That’s a growth rate of 64.7%.

Most growth is happening along city edges.

When you’re looking for stark demographic change in ATX, look to East Austin.

Between 2010 and 2020, East Austin neighborhoods grew both whiter and older. In that time frame, the share of Black and Hispanic older adults declined, while the population of older white adults grew significantly.

Children are making up a smaller share of the population.

The number and proportion of children under five years old is smaller now than it was a decade ago. Austin also has a lower percentages of people under 18 — 19.4% — compared to higher rates in Texas (25.8%) and the US (23%).

But Austin is still a young city.

The median age of Austin — 33 years old, up from 31 in 2010 — is still younger than its peer cities. Compare to:

The US: 38.8
Texas: 35.6
Dallas: 33.6
Houston: 34.2
San Antonio: 35.9

The balance of older adults, younger adults, and children can foresee the economic growth potential of a city. Researchers look at a “dependency ratio,” or a measure of the proportion of dependents to the working population. Austin’s dependency ratio is 40.7, which is substantially lower than the US (63.6) and Texas (62.4).
