Opportunity Data – Location Affordability Index

This layer displays the percentage of household income a family earning 50% of area median income (AMI) might pay on housing and/or transportation costs. Data is from the Location Affordability Index (LAI) Version 2, which estimates these costs at the neighborhood level for all populated areas across the United States.

Public Transit Stops and Stations

This layer displays the locations of transit stops and stations. Data was acquired from the US Environmental Protection Agency (EPA) and is available for the 200+ metro areas.

National Transporation Atlas, 2014

Multiple layers from the 2014 release of the National Transportation Atlas (NTA) are now available through Community Commons. The US Department of Transportation releases this annual dataset displaying many transportation related features, ranging from highway and airport locations to fatality accident locations and hazardous material transportation routes. The ‘view map’ link displays the motor vehicle fatality accidents. For additional indicators from the dataset, search the Map Room for the term NTA.

Location Affordability Index for Family at AMI

This layer displays the estimated percentage of household income for housing and transportation for a family earning the Area Median Income (AMI). The expected values for housing and transportation are modeled by HUD using data from the US Census Bureau and the US Department of Transportation, including:

  • The average household size for a family earning AMI in the neighborhood
  • The average number of workers, vehicles, and vehicle miles travelled for a family in the neighborhood
  • The average utility and rental costs or average utility and mortgage costs for a housing unit to accommodate the family size above
  • The proportion of housing units that are either rentals or owner-occupied in the neighborhood

Note: The LAI does not predict what families are actually paying to live in a particular area, but rather what a family would pay (either in USD or as a percentage of income) if average or reasonable housing and commuting conditions for a particular neighborhood were achieved.

Location Affordability Index for Family Below AMI

This layer displays the estimated monthly cost for housing and transportation for a low-income, single-parent family (earning 50% of the Area Median Income). The values for housing and transportation are modeled by HUD using data from the US Census Bureau and the US Department of Transportation, including:

  • The average household size for a single-parent family earning 50% AMI in the neighborhood
  • The average number of workers, vehicles, and vehicle miles traveled for a family in the neighborhood
  • The average utility and rental costs or average utility and mortgage costs for a housing unit to accommodate the family size above
  • The proportion of housing units that are either rentals or owner-occupied in the neighborhood

Note: The LAI does not predict what families earning 50% AMI are actually paying to live in a particular area, but rather what a family would pay (either in USD or as a percentage of income) if average or reasonable housing and commuting conditions for a particular neighborhood were achieved.

Fatal Motor Vehicle Crashes by Location, 2018

This layer displays the location or intersection of fatal crashes occurring in 2018. This layer can be toggled to view fatal crashes involving a drunk driver, and crashes with pedestrian fatalities.

Fatal Motor Vehicle Crashes by County, 2014-2018

This layer displays the number and rate of fatalities from motor vehicle crashes occurring between 2014 and 2018, aggregated by county. Unlike typical mortality data, this data layer represents the location of the fatal crash, and not the county of the decedent’s residence.

Fatal Motor Vehicle Crashes by Location, 2017

This layer displays the location or intersection of fatal crashes occurring in 2017. This layer can be toggled to view fatal crashes involving a drunk driver, and crashes with pedestrian fatalities.
