City-generated population estimates and projections
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.
- As of September 2021, Round Rock’s estimated population is 123,497 (within the city limits).
Updated city estimates: Upon release of the official April 1, 2020 Census population, the city recalculated its population estimates for April 2020-August 2021 using the 2020 Census figure as a baseline. Previous estimates for those dates had been based on the 2010 Census because the 2020 Census had not yet been released.
Estimates reflecting newly completed single-family units are added monthly. Estimates reflecting newly completed multifamily units are added quarterly in January, April, July, and October.
The Planning and Development Services Department also generates 20-year population projections into the future using the most recent Census as a baseline. A new set of projections is released after each Decennial Census. Projections for 2021-2040 using 2020 as a baseline will be released later this year.

American Community Survey
The US Census Bureau also collects a wealth of demographic information annually through the American Community Survey (ACS). Surveys are sent to only a sampling of households, so ACS data are estimates, not 100% counts. This allows responses to be processed and reported much more quickly than the decennial Census. Survey data is also grouped into 3-year and 5-year estimates. These multi-year estimates are generally more accurate because of the combined sample size, but are less current than the 1-year estimates.

Economic Census and Survey
The Bureau also collects the Economic Census every five years (those ending in ’02 and ’07), and an annual Economic Survey. The economic census provides a detailed portrait of the United States’ economy once every five years, from the national to the local level. There also are several related programs, including statistics on minority- and women-owned businesses. The Census of Governments is conducted at the same time. The Census of Agriculture is now conducted by the US Department of Agriculture.
