CHICAGO — Illinois’ overall poverty rate is the same as it was a half-century ago despite scores of state and federal aid programs and a dramatic drop in the number of older people struggling to get by, according to a new report that examines how the state has fared since President Lyndon Johnson declared a national War on Poverty.

Almost 15 percent of Illinois residents, about 1.9 million, lived below the federal poverty line in 2012, about the same as in 1960 before Johnson’s call to action, according to the report released Thursday by the Chicago-based Social IMPACT Research Center. It comes a day after Gov. Pat Quinn called on lawmakers to raise the minimum wage to $10 an hour and double a tax credit that helps low-income workers keep more of their earnings.
