Livability Index: Housing

The AARP Livability Index housing component measures metrics and policies that promote affordability, availability, and accessibility. The Scorecard scores statewide housing scores, and through our approach to equity can score each state’s lowest performing group among each state’s most heavily white, Black, Hispanic, and AAPI neighborhoods.

The Livability Index Transportation category score is a composite score of 11 housing indicators (5 metrics, 6 policies) in the AARP Livability Index: 


  1. Zero-step entrances 
  2. Availability of multi-family housing
  3. Housing costs
  4. Housing cost burden
  5. Availability of subsidized housing


  1. State and local inclusive design laws
  2. State and local housing trust funds
  3. State manufactured housing protections
  4. State foreclosure prevention and protection
  5. State accessory dwelling unit support
  6. State and local plans to create age-friendly communities

Equity adjustment:

The top 10% of all neighborhoods (census block groups) in each state with nonzero population with the highest percentage of population that is Asian, Black, Hispanic, and White were identified.  For some states, more than 10% of non-zero-population block groups were 100% white; in these states all such block groups were included.

The Housing category score for each 10% selection of block groups was then calculated using the exact same methodology used to calculate Livability Index scores at other geographies, which is a population-weighted average of all component block groups.  Category scores for the state and each 10% selections are displayed.  For the equity adjusted metric score, the lowest of the four 10% selections is scored and ranked.

The Livability Index is a tool designed to evaluate every US communities’ livability from neighborhood to neighborhood. Some indicators look as far down as the census block, block group, tract, or high school district, while others use data sources at higher levels of geography such as metro area, city, or county. For the Scorecard, we aggregated scores across neighborhoods to provide a state-level rating for transportation. However, transportation systems vary across neighborhoods, cities, counties and regions within a state. To search for a home or neighborhood by zip code, visit
