The Area Deprivation Index - 3 (ADI-3) is an extension of G.K. Singh's 2003 version of ADI (G.K. Singh. Area deprivation and widening inequalities in US Mortality, 1969-1998. Am. J. Public Health, 93, 1137-1143 (2003). Https://doi.org/10.2105/AJPH.93.7.1137).

This data file includes both the unidimensional ADI value and values for the three factors identified by Berg et al.
