This map layer displays the change (+/-) in Area Deprivation Index (ADI) scores between the 2013 and 2015 datasets. The ADI is a rankings of neighborhoods by socioeconomic status disadvantage in a region of interest (e.g. at the state or national level). It includes factors for the theoretical domains of income, education, employment, and housing quality. It can be used to inform health delivery and policy, especially for the most disadvantaged neighborhood groups. The 2015 ADI (v2.0) was constructed using the 2011-2015 5-year estimates from the US Census' American Community Survey. The methods are identical to the 2013 ADI construction.
