Together with the Park and the Farms, the City is part of the older, southern Pointes, which have a greater overall population density than the northern Pointes (Grosse Pointe Woods and Grosse Pointe Shores). These areas became heavily populated 1910-1930 as one of Detroit's first commuter suburbs; in the previous century Grosse Pointe was home to cottages, resorts, farms, and widely-spaced lakefront mansions. Grosse Pointe ("the City"), Grosse Pointe Farms, and Grosse Pointe Park make up the Grosse Pointe South High School district. Downtown Grosse Pointe, along Kercheval Avenue from Neff to Cadieux, nicknamed "The Village," is considered by many to be the central downtown for all five of the Grosse Pointes, although each of them (except Grosse Pointe Shores) has several blocks of retail.
