The Low-Income Housing Tax Credit (LIHTC) Developments (Statewide) is the most important resource for creating affordable housing in the United States today.

Putting the "Choice" in Housing Choice Vouchers (Part 3). This report was produced by the Chicago Area Fair Housing Alliance (CAFHA) as part of the Housing Choice Voucher Advocacy Project. It is the third in a series of reports produced by CAFHA documenting the history and continuing problems of segregation in the operation of public housing and the Housing Choice Voucher program in the Chicago metropolitan region. Staff of the Voorhees Neighborhood Center had the opportunity to work with this group on analyzing the data. The report maps the location of the Housing Choice Vouchers in the Chicago metropolitan region to demonstrate the need for affirmative efforts to provide greater access to areas of opportunity for families using vouchers. The full report can be found at For more information on CAFHA please visit their website site

Three tables that are found in the report are available here in excel format. All tables include data for Chicago by Community Areas and for the Chicago 6 county region by municipality.

Although IHARP goes to great lengths to verify and update the housing information presented in our databases, unfortunately we can not claim the data to be free from errors or be fully up to date. Data was received by housing funders such as the US Department of Housing and Urban Development (HUD) the Illinois Housing Development Authority (IHDA) and the City of Chicago's Department of Housing (DOH). However, the data funders provide on their own developments is often incomplete, inconsistent or simply incorrect. IHARP continues to search alternate data sources and reconcile discrepancies but mistakes are likely to remain. Please refer to the data dictionary for field definitions.
