Greater Grand Crossing is one of the 77 community areas of Chicago, Illinois. It is located on the city's South Side. History Etymology The name "Grand Crossing" comes from an 1853 right-of-way feud between the Lake Shore and Michigan Southern Railway and the Illinois Central Railroad that led to a frog war and a crash that killed 18 people. The crash was the result of Roswell B. Mason (later to serve as mayor of Chicago) illegally constructing railroad tracks, on behalf of the Illinois Central, across another railroad company's tracks. Due to the lack of safety at the crossing, trains made complete stops here and therefore industry developed around the area to cater to the railroad workers. Nineteenth century The area was developed by Paul Cornell, the developer of what is now Hyde Park, Chicago, throughout the 1870s. Grade separation did not occur at the rail crossing until 1912. Greater Grand Crossing was historically a railroad suburb made up of five, independently developed, older ethnic neighborhoods. The Grand Crossing and Brookline neighborhoods were predominantly made up of German immigrant craftsmen, farmers and factory workers; Essex had residents of English, Irish and Scottish immigrants who worked for the railroads; Brookdale was settled mostly by Chicago-born residents employed in the building trades and by the railroads; and Park Manor, the last of these smaller neighborhoods to develop, had residents who were predominantly of east-coast Yankee stock. Twentieth century At the start of the twentieth century, portions of Greater Grand Crossing like other neighborhoods in Chicago made the transition from open space and farmland to bungalow neighborhood. Demographics By the 1930s, the railroad workers residing in the neighborhood were joined by Swedes and Italians. Throughout the next two decades, African Americans began moving into the neighborhood from the overcrowded Black Belt and that's when Grand Crossing's White residents began to move out of the neighborhood. During the 1950s, the Black population of the neighborhood rose from 6% to 86%. According to data from the 2014-2018 American Community Survey compiled by the Chicago Metropolitan Agency for Planning, there were 30,805 people and 12,230 households in Greater Grand Crossing. The racial makeup of the area was 1.1% White, 96.2% African American, and 1.5% from other races. Hispanic or Latino of any race were 1.2% of the population. In the area, the population was spread out, with 32.4% under the age of 19, 17.6% from 20
