This document discusses the development and use of an area deprivation index (ADI) to measure socioeconomic status for patients based on their census block group. The ADI was developed by Singh in 2003 using 17 census measures of education, employment, income, and living conditions. For Utah, it assigns each census block group an ADI score using Singh's coefficients calculated from 2000 census data. Higher ADI scores indicate more deprivation. The Utah ADI has been used by Intermountain Healthcare to assess community health needs, identify high-risk patients, and study the impact of deprivation on conditions like hypertension. However, it has limitations since it uses area-level data as a proxy for individual characteristics.
