The Chicago Southland is a region comprising the south and southwest suburbs of the City of Chicago in the U.S. state of Illinois. Home to roughly 2.5 million residents, this region has been known as the Southland by the local populace and regional media for over 20 years. Despite this relatively recent term, some older native Southlanders and current local advertisements colloquially refer to the Southland as the Southside, meaning on the southern side/border of Chicago as extended into the suburbs since some of them previously lived on Chicago's Southside but moved to the suburbs during post WWII white flight.
