Data Dashboards are created by the Assessor's Office to allow viewers to review assessments at each stage of the assessment process. In the first stage, the Assessor's Office sets values and processes appeals. In the second and final stage, the Cook County Board of Review adjusts those values based on appeals filed in their office. The Dashboards provide a clear view of how the tax burden is split between residential and commercial property owners. They also show the burden shifts at each stage. There are Dashboards that can be filtered by townships and municipalities below. See the options below.
