Quincy, known as Illinois' "Gem City," is a river city along the Mississippi River and the county seat of Adams County. As of the 2010 census the city held a population of 40,633. The city anchors its own micropolitan area and is the economic and regional hub of West-central Illinois, catering a trade area of well over 300,000. During the 19th Century, Quincy was a thriving transportation center as riverboats and rail service linked the city to many destinations west and along the river. It was Illinois' third-largest city, surpassing Peoria in 1870. The city holds several historic districts, including the East Side Historic District and the South Side German Historic District showcasing the architecture of Quincy's many German immigrants from the late-1800s.
Today, Quincy remains a prominent river city. It has been twice recognized as an All-American City and is a participant in the Tree City USA program. In the fall of 2010, Forbes Magazine listed Quincy as the eighth "Best small city to raise a family."
Quincy sits on the banks of the Mississippi River. For centuries the site was home to Sauk, Fox and Kickapoo Native American tribes.
