With low housing costs, exceptional health care, quality schools and a wide range of recreational activities and tourist attractions, it’s no wonder Rock Island County is home to nearly 150,000 residents and thousands of visitors each year.
Rock Island County is part of the Quad Cities Metropolitan Area of approximately 360,000 residents, nestled along the Mississippi River on the Illinois/Iowa border between Chicago and Des Moines.

On February 9, 1831 the Illinois General Assembly established Rock Island County and defined its boundaries. In 1833 early pioneers approved formation of a county government with the first county election held on July 5th of that year. In 1856 petitions were submitted to the County Board requesting the formation of townships during the next election in November. In this election Col. George Davenport, John W. Spencer and George W. Harlan were the first County Commissioners elected along with Benjamin Axe being chosen first Sheriff and Levi Wells first County Coroner. This township form of government is still in existence after nearly 150 years.
