Theory: As the ''structural linchpin'' of American race relations, res
idential segregation has important implications for blacks' and whites
' thinking about race. Considered here is the impact of residential co
ntext-living in predominantly black or racially heterogeneous neighbor
hoods in the city or the suburbs-on feelings of racial solidarity amon
g black Americans. Hypotheses: The social density hypothesis predicts
stronger racial solidarity among blacks who live in the city and in pr
edominantly black neighborhoods. The social salience hypothesis predic
ts stronger solidarity among suburbanites and residents of racially mi
xed neighborhoods. The identity supremacy hypothesis predicts no relat
ionship between residence and sense of racial solidarity. Methods: Reg
ression analysis of survey data for a subsample of black urbanites and
suburbanites in the Detroit metropolitan area. Results: The statistic
al results are most consistent with the social density hypothesis. The
conclusion centers on the possible implications of black suburbanizat
ion and changing levels of racial solidarity among blacks.
