The Planning and Development Services Department generates monthly population estimates and future population projections based on recent development activity. The population estimate is updated monthly to reflect completed single-family units, and completed multifamily units are added twice a year in October and April. Projections are adjusted every ten years as decennial Census figures are released.
- As of November 2019, Round Rock’s estimated population is 117,169 (within the city limits, i.e. not including the MUDs).
