Census data: Round Rock becoming increasingly diverse

While data for Round Rock from the latest U.S. Census confirms that the city continues to be fast-growing, a closer look in the City’s recent Census Release Report reveals other interesting trends in the city’s demographic makeup. 

Round Rock’s official population count totaled 119,468 for the 2020 Census, an increase of 19.6% over its previously recorded population of 99,887 in the 2010 Census. 

Like many cities in Texas, Round Rock is growing more racially diverse; while the number of Round Rock residents who responded that they are only one race has decreased from 96.2% of the total population to 82.9% over the last 10 years, the number of people who are of two or more races increased from 3.8% to 17.1%. For the 2020 Census, the U.S. Census Bureau made improvements to the questions on race and Hispanic origin, also known as ethnicity. Almost one-third of Round Rock’s population self-identified as Hispanic or Latino in the 2020 Census. 

In 2020, adults over the age of 18 make up a larger share of Round Rock’s total population than in 2010. The number of people under the age of 18 remained constant over the last decade, even as the city’s population grew, while the number of people over the age of 18 grew by 19,393.  

The City of Round Rock also closely tracks housing and economic indicators to inform planning decisions. Over the last 10 years, 8,621 housing units were added, which included more variety of housing unit types, such as single-family common lot and higher density multifamily developments. Vacant housing units decreased from 5.8% of total inventory to 5%, demonstrating that the additional units were necessary to meet housing demand.  

The Planning and Development Services Department generates monthly population estimates based on housing units, occupancy, and household size using the most recent Decennial Census as a baseline. For more information, visit the City’s Demographic and Census Information page.
