General description

The Area Deprivation Index (ADI) ranks neighborhoods in a particular region according to levels of affluence and deprivation. Its design is based on 17 American Community Survey (ACS) variables, covering education, employment, housing, and income; in essence, social determinants of health (SDOH). Health outcomes such as 30-day hospital readmission rates, all-cause mortality, cancer incidence and deaths, cardiovascular disease fatalities, and cervical cancer incidence have all been linked to high levels of deprivation.

The ADI provides national percentile rankings at the block group level from 1 to 100. The percentiles are constructed by ranking the ADI from low to high for the country. It is followed by grouping the block groups into bins corresponding to each 1% range of the ADI. Block groups with a ranking of 1 reflects least disadvantaged neighborhood conditions within the country while those with a ranking of 100 indicates the most disadvantaged.

Limitations

• Can only be linked to census block groups since other geographic units like 5-digit zip codes and ZCTA will not be valid.
• Uses the American Community Survey (ACS) Five Year Estimates in its construction. As a result, it is subject to the limitations of the source data.
