Third-, fourth- and fifth-generation Irish Americans can be found throughout Brooklyn, with moderate concentrations enduring in the neighborhoods of Windsor Terrace, Park Slope, Bay Ridge, Marine Park and Gerritsen Beach. Historical communities also existed in Vinegar Hill and other waterfront industrial neighborhoods, such as Greenpoint and Sunset Park. Paralleling the Italian American community, many moved to Staten Island and suburban areas in the postwar era. Those that stayed engendered close-knit, stable working-to-middle class communities through employment in the civil service (especially in law enforcement, transportation, and the New York City Fire Department) and the building and construction trades, while others were subsumed by the professional-managerial class and largely shed the Irish American community's distinct cultural traditions (including continued worship in the Catholic Church and other social activities, such as Irish stepdance and frequenting Irish American bars).
