As part of our full report on unincorporated Cook County, the Civic Federation compiled profiles of the unincorporated areas in the six townships that contain a majority of the total unincorporated Cook County population: Bremen, Lemont, Leyden, Maine, Northfield and Orland. Understanding more about the unique characteristics of these areas will help County and municipal officials, as well as unincorporated residents, develop plans to incorporate.

[1]  The tax bill projections in this study are for illustrative purposes only. They show an estimate of how much property tax bills for parcels in unincorporated tax codes might increase if those parcels had been annexed into nearby incorporated tax codes in tax year 2012. They do not represent actual tax bill changes for particular parcels, but instead show the order of magnitude of the change that unincorporated areas might experience.
