“…For these reasons, the current article relies instead on King's (1997) method of ecological inference (King's EI) to derive estimates for EIP takeup rates by race. King's EI has been viewed favorably by federal judges in voting rights cases (Greiner, 2007), and it is used widely in similarly motivated social science research (Liu, 2001;Orey et al, 2011;Roch & Rushton, 2008;Tolbert & Grummel, 2003;Tolbert & Hero, 2001;Voss, 1996Voss, , 2000Voss & Miller, 2001). Nonetheless, the method is not without its critics (Anselin & Cho, 2002;Calvo & Escolar, 2003;Cho, 1998;Freedman, Klein, Ostland, & Roberts, 1998;Greiner, 2007), and, consequently, the estimates that it produces are supported by, and discussed within the context of, supplementary decile analyses and geovisualizations (refer to the "Data and Method" section below).…”
