Multidimensional Housing and Environmental Quality Index
The Multidimensional Housing and Environmental Quality Index (HEQI) is a one-time research study that was developed based on the World Health Organization’s Housing and Health Guidelines and used the 2019 American Housing Survey (AHS) data. The study provides information on residential environment exposure that can be used to inform strategies to address climate change. HEQI included multiple dimensions of healthy housing with the use of 10 domains: fuel combustion, dampness and mold, pests and allergens, lead paint, high indoor temperatures, low indoor temperatures, crowding, injury hazards, inadequate water and sanitation, ventilation. The final version of the HEQI included 43 AHS variables across the 10 domains. Dampness and mold, low indoor temperatures, household crowding, and inadequate water and sanitation were the four most documented domains.
