“…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.…”
