2015 annual city population estimate: 105,405

Within the Round Rock city limits

The Planning and Development Services Department generates monthly population estimates and future population projections based on recent development activity. Projections are adjusted every ten years as decennial Census figures are released.

  • As of April 2015, Round Rock’s estimated population is 105,405 (within the city limits).
  • Note: Annual population estimates typically jump from the previous month because they include residents of recently-completed multifamily projects, which are not included in estimates for preceding months.
