“Every city or metropolitan area in the U.S. has higher- and lower-income neighborhoods. The extent to which these neighborhoods differ in their average socioeconomic status, however,  varies considerably. Moreover, this socioeconomic residential sorting has grown substantially in  the last 40 years (Reardon and Bischoff 2011a; Reardon and Bischoff 2011b; Watson 2009); the  bulk of that growth occurred in the 1980s and in the 2000s.  We refer to the uneven geographic distribution of families of different income levels  within a metropolitan area as “family income segregation” or, more simply, “income segregation.” Our use of the term “segregation” is descriptive; it denotes the extent to which  families of different incomes live in different neighborhoods; it does not imply any particular cause of these residential patterns. We focus on the segregation of families by income primarily because children generally live in family households. Segregation is likely more consequential for children than for adults2 for two reasons. First, most children spend a great deal of time in  their neighborhood, making that immediate context particularly salient for them, while adults generally work and socialize in a larger geographic area. Second, for children, income segregation can lead to disparities in crucial public amenities, like schools, parks, libraries, and recreation. We describe the patterns and trends in family income segregation over the last 40 years.”
