Dialysis Facility Area Deprivation Index (ADI) National Ranks
Each dot on the map represents a dialysis facility. Red indicates a facility is in a higher disinvested neighborhood, while blue indicates the facility is in a less disadvantaged neighborhood.
The ADI1
ADI reflects a geographic area's level of socioeconomic deprivation. This multifaceted proxy measure is used for assessing socioeconomic disadvantage that includes social risk factors.
It is a metric originally developed by the Health Resources & Services Administration and more recently refined, adapted, and validated to the census block group by researchers at the University of Wisconsin-Madison2.
The index uses 17 U.S. census data variables within the American Community Survey (ACS) data, such as level of education, employment, income, housing, transportation, and living conditions to develop scores for individual census block groups indicating levels of socioeconomic disadvantage. The scores are based on the national percentile rank of scores, such that larger values indicate more socioeconomic disadvantage. A national score of 100 indicates that the census block group is in the top 1% of all block groups in the United States in terms of disadvantage.
