Chicago, on the shores of Lake Michigan, is a global city of 2.7 million. It is the center of America’s third largest metro economy, which produces more than US$690 billion in gross regional product. Almost one-quarter of households had earnings exceeding US$100,000 in 2016, according to the US Census. Chicago companies employ over four million people, many of them at the more than 400 major corporations that have their headquarters there. In March 2018, its unemployment rate was an enviable 5.3 percent, nearly the lowest since the government started tracking it.
