This dataset contains information for all the affordable housings in the Champaign County, including name, location, and number of units, and affordable housing program. The data is retrieved from Housing Authority of Champaign County Annual Report, HUD LIHTC Database, and Section 8 and Section 202 housing listing.

HUD’s Multifamily Housing property portfolio consist primarily of rental housing properties with five or more dwelling units such as apartments or town houses, but can also include nursing homes, hospitals, elderly housing, mobile home parks, retirement service centers, and occasionally vacant land. HUD provides subsidies and grants to property owners and developers in an effort to promote the development and preservation of affordable rental units for low-income populations, and those with special needs such as the elderly, and disabled. The portfolio can be broken down into two basic categories: insured, and assisted. The three largest assistance programs for Multifamily Housing are Section 8 Project Based Assistance, Section 202 Supportive Housing for the Elderly, and Section 811 Supportive Housing for Persons with Disabilities. The Multifamily property locations represent the approximate location of the property. The locations of individual buildings associated with each property are not depicted here. Location data for HUD-related properties and facilities are derived from HUD's enterprise geocoding service. While not all addresses are able to be geocoded and mapped to 100% accuracy, we are continuously working to improve address data quality and enhance coverage. Please consider this issue when using any datasets provided by HUD. When using this data, take note of the field titled “LVL2KX” which indicates the overall accuracy of the geocoded address using the following return codes: ‘R’ - Interpolated rooftop (high degree of accuracy, symbolized as green) ‘4’ - ZIP+4 centroid (high degree of accuracy, symbolized as green) ‘B’ - Block group centroid (medium degree of accuracy, symbolized as yellow) ‘T’ - Census tract centroid (low degree of accuracy, symbolized as red) ‘2’ - ZIP+2 centroid (low degree of accuracy, symbolized as red) ‘Z’ - ZIP5 centroid (low degree of accuracy, symbolized as red) ‘5’ - ZIP5 centroid (same as above, low degree of accuracy, symbolized as red) Null - Could not be geocoded (does not appear on the map) For the purposes of displaying the location of an address on a map only use addresses and their associated lat/long coordinates where the LVL2KX field is coded ‘R’ or ‘4’. These codes ensure that the address is displayed on the correct street segment and in the correct census block. The remaining LVL2KX codes provide a cascading indication of the most granular level geography for which an address can be confirmed. For example, if an address cannot be accurately interpolated to a rooftop (‘R’), or ZIP+4 centroid (‘4’), then the address will be mapped to the centroid of the next nearest confirmed geography: block group, tract, and so on. When performing any point-in polygon analysis it is important to note that points mapped to the centroids of larger geographies will be less likely to map accurately to the smaller geographies of the same area. For instance, a point coded as ‘5’ in the correct ZIP Code will be less likely to map to the correct block group or census tract for that address. In an effort to protect Personally Identifiable Information (PII), the characteristics for each building are suppressed with a -4 value when the “Number_Reported” is equal to, or less than 10.

Special Tabulations of Householdsby Income, Tenure, Age of Householder, and Housing ConditionsThe Economic and Market Analysis Division (EMAD) "Special Tabulations" data retrieval system produces tabular statistical summaries of counts of households by tenure, by income intervals, by age of householder, by size of household, by housing conditions based on the 1990 and 2000 Census, for select geographic areas in the United States. This system allows a user to extract data to conduct a longitudinal analysis of changes in a particular area.These special cross tabulations of decennial and ACS census data are the most detailed available for a qualitative analysis of housing demand based on incomes and age of householder. These data are a key element in the allocation formulae for the Section 8 and the Section 202 rental assistance programs, as well as a key element in EMAD qualitative demand market analysis activities for review of program applications and multifamily mortgage insurance applications submitted to FHA.For 1990 and 2000, the system contains decennial data for all counties and county equivalents in the United States, places with populations of 50,000 (subject to disclosure requirements), the nation, all states and the District of Columbia, and MSAs and PMSAs (except those in New England) based on the 1999 OMB definitions in effect at the time of the 2000 Census. Year 2000 data are also provided for selected areas in the Commonwealth of Puerto Rico. Beginning in 2010, the system uses data from the Census ACS 5-year survey, which is available at the CBSA, State, and County level. A detailed description of the exact content and format of the database is presented in the Help section of the system (Uploader's note: this help section was not available due to 404 error).
