In the 1960s the Northeastern Illinois Planning Commission sought to foster cooperation between neighboring municipalities by encouraging the development of intercommunity councils, where representatives of local governments could deliberate on issues of common concern and attempt to coordinate regional planning. Similar councils exist in the early twenty-first century, including the South Suburban Mayors and Managers Association and the Barrington Area Council of Governments.
