The Area Deprivation Index (ADI) was created by University of Wisconsin researchers to provide a score for neighborhoods based on their level of disadvantage. This study will characterize differences in ADI in rural vs urban areas, summarize the existing literature on ADI, and describe expert considerations for utilizing the ADI for future policy.

This mixed methods study includes three main components:

• Review existing peer-reviewed literature regarding the use of ADI. This component will consider the association between ADI and outcomes related to access, utilization, and/or quality of care as well as how ADI is being used in the peer-reviewed literature to date with a focus on studies considering rural areas specifically.
• Utilize key informant interviews to understand the limitations and considerations of using the ADI as a measure of socioeconomic vulnerability for informing rural health policy.
• A quantitative analysis will compute, compare, and provide descriptive statistics of rural vs urban communities; consider differences and implications of different methods for aggregating ADI rank from the census block group level to varying geographic levels (e.g. 9-digit ZIP codes, 5-digit ZIP codes, and counties); link ADI to Frontier and Remote Area codes; and explore the content and implications of data missingness.

  The Area Deprivation Index (ADI) was developed to capture area-level social deprivation for use in policy and research. In this literature review, researchers find that the use of the ADI in research is common.
