Affordability Risk Index

The Affordability Risk Index (ARI) is a tool that identifies those Census tracts that are becoming less affordable over time.  Tracts where the risk of losing affordable housing is greatest receive the highest score (5). The ARI uses US Census data to measure change over time (between 2000 and 2013) across various factors typically assumed to indicate affordability loss, such as median household income; median home value; families below the federal poverty level; housing unit vacancy; renter tenancy; individuals with a 4-year degree or higher.

Due to concerns with the timing of the posting of the 2017 Affordability Risk Index (ARI) update, the index scores have been removed from the final scoring consideration for all 2017 LIHTC applications.
IHDA will rerun the Affordability Risk Index data for 2018 as soon as updated data is available and will republish the ARI – including the mapping tool and methodology – at that time.
