One out of every thirteen working people in the state of Illinois is employed by a non-profit organization, according to a new study. ” In 2003, the report says, 441,814 people worked for hospitals, schools, cultural institutions, social-service agencies and other Illinois groups organized under section 501(c)(3) of the federal tax code. That was more, for example, than the 406,300 workers in metal and machinery manufacturing or the 312,900 in finance and insurance.”
