City of Houston Average Household Size by Tenure

The American Community Survey (ACS) 1-Year and 5‑Year estimates for Houston, TX provides data on the average household size by renter and owner-occupied households. The ACS 5-Year estimates are based on surveys collected over a five-year period, which produces more reliable statistics for smaller towns and neighborhoods due to a larger sample size.

Use 5-Year Estimates for: Small geographic areas (tracts, block groups, neighborhoods), trend analysis when annual data is unavailable, and/or planning and policy decisions requiring higher reliability.

Use 1-Year Estimates for: Large geographic areas (populations of 65,000 or more), more current data for cities, counties, and states, and/or trend analysis of annual data.
