Introduction: Illinois Download PDF
A large influx of settlers to Illinois in the 19th century led to the cultivation of the prairie lands across the state, and agriculture began to expand quickly with focus in the Chicago area. Services, finance, and manufacturing have since become leading economic activities in Illinois. Even with the strength of other industries, agriculture remains a vital industry as Illinois ranks in the top five most productive farming states in the nation.
Today, the Chicago metropolitan area accounts for two-thirds of the population in Illinois. As the third largest city in the United States, Chicago is also recognized as a commercial and industrial center, serving as host to the world’s first and largest derivatives exchange market (Chicago Mercantile Exchange). The city is also a leading cultural center in North America, featuring world-renowned museums and libraries.
