This article links the statistical data on residential segregation wit
h the informal practices of individuals. Local gatekeeping practices c
ontribute to the perpetuation of segregation and further explain the p
atterns of macro-level analyses. This research focuses on the communit
y of Greenpoint, a predominantly white, working-class neighborhood in
Brooklyn. The study describes the strategies used by residents of Gree
npoint to accomplish residential segregation and to maintain a predomi
nantly white non-Hispanic neighborhood. The process of informal housin
g networking is supported by the arrangements of local institutions.
