Renter-occupancy rate, explained

What it measures

The renter-occupancy rate is the percentage of occupied housing units that are occupied by renters rather than owners. It is the mathematical complement of the homeownership rate, the two sum to 100%. The denominator is occupied housing units; vacant homes are excluded. The metric captures both renters in apartments and renters of single-family homes; the Census does not distinguish by structure type in this specific table.

Published in ACS Table B25003 alongside the homeownership rate, for the same geographies.

Why it matters

Renter share is a structural feature of a local housing market with major downstream effects. High-renter metros have more housing turnover (renters move more frequently than owners), more rental-market volatility, larger fraction of household income going to housing payments rather than equity, and different political dynamics around housing policy. Cities with renter shares above 60% (New York, San Francisco, Boston) have organized renter constituencies that shape rent-stabilization, eviction-protection, and zoning debates. The renter share also matters for school enrollment forecasting, renter households are more likely to relocate during the school year.

How the Census measures it

Same table as homeownership: ACS Table B25003. The published rate is renter-occupied / (owner-occupied + renter-occupied) × 100.

How to read the numbers

The US renter share is about 35%. The highest-renter metros are concentrated in expensive coastal markets where ownership is unaffordable for most working-age households: New York, San Francisco, Los Angeles, Boston, Honolulu. Small college towns also post very high renter shares because the student population dominates. The lowest renter shares are in slow-growing rural areas with abundant cheap housing and low transient population. A renter share that has risen by more than 5 points in a decade usually signals either a shift to apartment-heavy construction, falling affordability that pushed buyers into the rental market, or both.

Caveats and limitations

Same caveats as homeownership rate. Renter share doesn't distinguish between voluntary renters (people who prefer to rent for flexibility or lifestyle reasons) and frustrated would-be buyers priced out of ownership. Cross-reference with the home-value-to-income ratio to interpret.
