Where in the United States is Iowa? How about private education?

Iowa is located in the great plains of the midwest, and its capital is Des Moines. The early immigrants in this area came from Wisconsin and Illinois, most of whom came from northwest Europe. Iowa is basically a plain with a typical inland humid climate, with an average annual temperature of about 10 degrees Celsius. There is not much industry in this state, but agriculture is quite developed, mainly corn and soybeans. There are about 3 million people in this state. As far as I know, most of them are white Americans, and few are Chinese.
