The South Side Irish is the large Irish-American community on the South Side of Chicago, Illinois. After 1945, a large-scale movement to the suburbs occurred because of white flight and the steady upward social mobility of the Irish.Although their population has spread out, Irish Americans continue to make up the majority of the ethnic white American population on the south side of Chicago, especially in Canaryville, Bridgeport, Scottsdale, Mount Greenwood, and parts of Morgan Park.
