“…It assumes its minimum value of zero when only one of the groups is represented in the neighborhood. Many scholars have confirmed the usefulness of the entropy index and its numerous desirable technical qualities, such as handling multiple groups readily, easy calculation, and decomposability (Allison, 1978;Fischer, 2003;Iceland, 2004;James and Taeuber, 1985;Reardon and Firebaugh, 2002;Reardon and Yun, 2001;White, 1986). Entropy has been chosen as the preferred measure in a wide range of studies on income inequality and economic segregation (Firebaugh, 1999;Fischer, 2003;Fischer et al, 2004;Fong and Shibuya, 2000;Harsman and Quigley, 1995;Jones and Weinberg, 2000;Talen, 2006;Telles, 1995;White, 1986), and we follow in this tradition.…”
