With Chicago in the north east, small industrial cities and great agricultural productivity in central and northern Illinois, and natural resources like coal, timber, and petroleum in the south, Illinois has a diverse economic base and is a major transportation hub.

Illinois is bordered on the east by the state of Indiana and to the south by Kentucky. Most of the western border with Missouri and Iowa is the Mississippi River; Kaskaskia is an exclave of Illinois, lying west of the Mississippi and reachable only from Missouri. The north eastern border of Illinois lies within Lake Michigan, within which Illinois shares a water boundary with the state of Michigan.
