Rethinking the “buffering” theory of neighborhood racial transition

In metropolitan areas with significant numbers of Latinx and Black people, Santiago (1991) hypothesized that Latinx groups may “buffer” white neighborhoods from Black ones. Farley and Frey (1994, https://doi.org/10.2307/2096131 ) subsequently suggested that Latinx and Asian groups provide a social or spatial “buffer” that enables White and Black neighborhood coresidence. In predominantly White spaces, increases in the neighborhood shares of Latinx and Asian populations moderates White resistance to the presence of Blacks, and this helps explain growing neighborhood racial diversity in the United States. This essay suggests expanding the thesis in several ways. We first consider reversing the theory wherein Latinx and Asian groups provide a “buffer” enabling White and Black coresidence because Blacks are cushioned from the actions of Whites. This view requires us to include not only White tolerance but also White intolerance in the buffering logic. Second, we point out that racially mixed neighborhoods may also come about because people want to live in such diverse environments. Third, this leads to a consideration of processes of neighborhood racial mixing that include the roles of real estate markets actors in shaping neighborhood outcomes as well as the motivations of Latinx, Asian, and mixed-race populations.
