Area Deprivation Index
Area Deprivation Index (ADI) is a measure of SES, determined from 17 variables including income, education, employment, and housing quality collected by the United States Census Bureau.15 By assigning a national percentile to each residential address at the Census Block level, ADI allows for quantification of SES on a scale of 1 to 100, where lower percentiles represent less deprivation (higher SES). National ADI percentile was collected for each patient’s home address using the 2018 Neighborhood Atlas (University of Wisconsin School of Medicine and Public Health).
