Income segregation in the United States grew substantially from 1970 to 2007 (Bischoff & Reardon, 2014; Jargowsky, 1996; Reardon & Bischoff, 2011a, 2011b; Watson, 2009). Income segregation grew sharply in the 1980s, changed little in the 1990s, and then grew again in the early 2000s. A primary cause of this growth in segregation has been the rise in income inequality over the last four decades (Bischoff & Reardon, 2014; Reardon & Bischoff, 2011b; Watson, 2009). Income inequality in the U.S. continued to rise in the 2000s.
