CHAS DATA

1. CHAS DATA Todd Richardson U.S. Department of Housing and Urban Development Office of Policy Development & Research

2. Presentation Summary • Accessing the data • Downloading the data • Understanding the data • Using the data

3. Accessing the data • State of the Cities Data System • http://socds.huduser.org/scripts/odbic.exe/chas/index.htm? • HUDUSER - data sets - consolidated plan • http://www.huduser.org/datasets/cp.html

4. State of the Cities • Housing Problems Table • 1990 Data • All Households, White-nh, Black-nh, Hispanic • 2000 Data • All Households, White-nh, Black-nh, Hispanic, Asian-nh, Native American-nh, Pacific Islander-nh, Mobility and Self-Care Limitation

5. State of the Cities • Affordability Mismatch • 2000 Data • Occupancy, age, and vacancy rate of units affordable to persons in different income categories

9. Other helpful data at SOCDS • http://socds.huduser.org/index.html • Data from the 1970, 1980, 1990, and 2000 Census • Current Employment Statistics for City Residents • Special City Extracts from County Business Patterns • FBI Crime Data • Building Permits Database • Urban Public Finance Data

10. HUDUSER - Data Sets - Consolidated Plan • Detailed Tables • 59 tables • Multiple Geographic Levels • State, County, Place, Consolidated City, Tract (part), a few tables at Block Group level • Different Ways to Download • By State (DBF files only) • Nationally (SAS, SPSS, DBF Files)

14. Detailed Tables • Example Table to Download: • A1A040.DBF - Table, Geographic Summary Level, Data Format • A Tables • General CHAS data tables at six geographies mentioned • B Tables • Less disaggregated CHAS data at Block Group level • F Tables • Tables created for running various formulas

15. Detailed Table Tips • Also download the data dictionary, files are highly disaggregated • Use the highest level geography that makes sense • Rounding issue with special tabulation data • Mapping with Tract and Block Group Data • The tract (part) and block group (part) data split at place boundaries requiring non-standard GIS shape files which HUD has created and can also be downloaded.

16. Downloading the Data • SOCDS data tables downloadable in Excel File • VERY IMPORTANT - USE NON-FRAMES VERSION OF SOCDS IN ORDER TO DOWNLOAD • HUDUSER data files are in zipped files. • The State Downloads, which most people will likely use, have data for every table and every geography all zipped into a single file. This allows the user to be selective about what they want to extract.

17. Understanding the Data • These data are largely built around HUD’s Low/Mod area definitions 30%, 50%, and 80% of HUD Area Median Family Income (HAMFI) • HAMFI is calculated based on the median income for a metropolitan area, assuming that is income for 4-person HH. • HAMFI is adjusted for family size

18. HAMFI vs. Poverty • On average, households at less than 30% of HAMFI equate to households at the poverty level. • However, in high cost/high income markets, the % of households less than 30% is much higher than poverty rate. Similarly in low cost/low income markets, the % of households less than 30% is much lower than poverty rate. • We use HAMFI as a proxy to account for different costs of living.

19. Example of 1999 HAMFI

20. Do not confuse CHAS data with CDBG Low/Mod Area Data • CDBG Low/Mod Area Data are NOT based on the special tabulation data. They are created using a routine that extrapolates from SF3 data. You can download CDBG Low/Mod Area Data from: http://www.hud.gov/offices/cpd/systems/census/lowmod/index.cfm

21. Housing Needs - CHAS • Housing Quality • Census Data weak measure on housing quality • Without complete kitchen or complete plumbing • Overcrowding • Greater than 1.01 persons per room • Severe Crowding GT 1.51 persons per room • Increased over past decade

22. Housing Needs (cont) • Affordability • Cost Burden - greater than 30% of income for housing • Severe Cost Burden - greater than 50% of income for housing

23. A3B. HOUSEHOLD INCOME IN 1999 BY HOUSING UNIT PROBLEM SEVERITY (35) Universe: Renter occupied housing units Household income less than or equal to 30.0% of HAMFI Lacking complete plumbing facilities or lacking complete kitchen facilities With 1.51 or more person per room, none of the needs above With 1.01 to 1.50 persons per room, none of the needs above Housing cost burden over 50.0 percent, none of the needs above Housing cost burden 30.1 to 50 percent, none of the needs above Zero income No housing unit problems Household income 30.1% to 50.0% of HAMFI (Repeat HOUSING UNIT PROBLEM SEVERITY ) Household income 50.1% to 80.0% of HAMFI (Repeat HOUSING UNIT PROBLEM SEVERITY ) Household income 80.1% to 95.0% of HAMFI (Repeat HOUSING UNIT PROBLEM SEVERITY ) Household income above 95.0% of HAMFI (Repeat HOUSING UNIT PROBLEM SEVERITY ) Using the Data: Example

26. Other Favorite Tables The F5 Tables: HOUSING UNIT PROBLEMS AND COST BURDEN BY HOUSEHOLD INCOME IN 1999 BY HOUSEHOLD TYPE • F5A – Owners with a mortgage • F5B – Owners without a mortgage • F5C – Renters of Single Family Homes • F5D – Renters of Multifamily Units

27. Other Favorite Tables • Mobility and Self-Care Limitations by housing needs and age of household members – Tables A7A, A7B, A7C • Housing Need by Income Breaks of 20%, 30%, 40%, 50%, 60%, 65%, 80%, 95%, 100%, 115%, 120% and 140% of HAMFI – Tables A6A & A6B

28. Other Favorite Tables • Poverty Rates with and without college students – Table A13 • Income and Age of Housing for Families with Children Age 6 and Under – Tables A14A and A14B

29. GIS – Shape Files for Census Tract (part) and Block Group (part) files • Shape files for Summary Levels 080, 090, and 091 are not standard products so HUD created them. You can download at: http://www.huduser.org/geo/summarylevel.asp
