This chevron-shaped community is one of Chicago's 16 lakefront neighborhoods near the southern rim of Lake Michigan 10 miles south of downtown. A working-class neighborhood, it is bordered by East 79th Street on the north, South Chicago Avenue on the southwest, a small stretch of East 95th Street on the south. With the Calumet River on the community's southeast side, South Chicago can be considered the gateway to the Calumet Region and the one of the four Chicago neighborhoods that are considered by the locals as part of Chicago's Southeast Side. The Southeast Side is a description that the city itself continues to resist, including this neighborhood with all of Chicago's South Side communities.
