This paper uses census tract data from the 2000 U.S. Census and the 2005-2009/2006-2010 American Community Survey to examine the locations of gay male and lesbian partnerships in 38 large U. S. cities.  Surprisingly, both the extent and the regional patterns of residential segregation of gays are similar to those for African Americans.  There is little evidence, however, to support the common assertions that gays concentrate in more racially and ethnically diverse neighborhoods.   Evidence for the popular notion that concentrations of gays lead to “revitalization” of central city neighborhoods.   Census tracts that start the decade with more gay men experience significantly greater growth in household incomes (and, therefore, presumably housing prices) and, for the Northeastern and Western cities, also greater population growth over the next decade than those census tracts with fewer gay men.  City census tracts with more lesbians at the start of the decade see no differences in population or income growth.
