Livability Index: Transportation

The AARP Livability Index transportation component measures metrics and policies related to convenience, safety, and options. In ranking statewide transportation factors, the Scorecard scores statewide transportation 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 Asian neighborhoods. The District of Columbia, Rhode Island, and Montana had the best statewide transportation scores, while 5 of the 6 lowest scoring states were in the Southeast: Alabama Georgia, Kentucky, Mississippi, and Tennessee.

The Livability Index Transportation category score is a composite score of 11 indicators (7 metrics, 4 policies) in the AARP Livability Index:


  1. Frequency of local transit service
  2. ADA-accessible stations and vehicles
  3. Walk trips
  4. Congestion
  5. Household transportation costs
  6. Speed limits
  7. Crash rate


  1. State and local Complete Streets policies
  2. State human services transportation coordination
  3. State volunteer driver policies
  4. 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 Transportation 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.
