Assessing Housing Market Conditions
-- Updating Census 2000 Data and Selected GIS Applications
This web page summarizes elements and resources presented by Warren Glimpse at the
Housing Choice Voucher Program,
26th Annual Conference, sponsored by
Quadel Consulting,
in Washington, DC.
A live GIS mapping demonstration of using GIS tools with Census 2000 geodemographic data
for the Houston, Texas area shows the interrelationships and benefits for
housing market analysis. Some parts of this presentation are summarized in the paper
"Neighborhoods and Geodemographic Analysis:
Using Data-Driven Decisionmaking Information in Local Coalitions," by Warren Glimpse.
This paper is referenced in the
Proximity Neighborhood Information Program.
Conference presentations also demonstrate use of the latest Census 2000 demographic data
and how these resources can be used in a range of application scenarios concerning housing
market analyses.
- 1990-2000 Census demographic trend comparative analysis profiles. Use these
trend profiles, further described at
http://proximityone.com/dp.htm#trends, to assess comparative geographic changes
in housing market and related demographic conditions.
- Options for Acquiring Map Files. Proximity, the Census Bureau, and other organizations
provide no fee access to map files that can be used in the applications described in this
session. These resource access options, and relative strengths and weaknesses,
will be reviewed in the session.
• Census Bureau -- http://www.census.gov/geo/www/cob/index.html
• Proximity -- http://proximityone.com/maps2000.htm
• Hard copy maps -- http://www.census.gov/geo/www/maps/CP_MapProducts.htm
- Using Census 2000 Summary File 3 Data. This national scope set of "richer
demographic" data was released by the Census Bureau in September 2002 and features the
baseline data for that will be included directly or indirectly in most housing market analyses.
The presentation summarizes the content and access to these data as described in the
web page http://proximityone.com/cen2000sf3.htm.
• Interactive access -- http://factfinder.census.gov
- National ZIP Code and Census Tract Demographic Databases. Using the Summary File 3
data, Proximity has developed a national scope demographic profile database at the ZIP code
and census tract levels of geography. More information on these data resources, and a
sample of this database for the State of Hawaii available for downloading, is available
at http://proximityone.com/hidmi1.htm.
These data may be directly loaded into a GIS application relating to housing market analyses,
discussed in the conference presentation.
- Housing Affordability Index. Proximity is assessing alternative measures of
housing affordability, and associated market indicators, using data resources described in the session. Application of a Housing
Affordability Index for the Houston, Texas area, by census tract, is described in the session.
Notes on Housing Affordability Index
scale: 0 to 100
100 * (annual housing costs/population) / max((annual housing costs/population) across all tracts)
the smaller the index, the more affordable the housing
annual housing costs are the composite of 12 times the monthly homeowner costs for mortgaged properties and 12 times the monthly gross rent for renter occupied properties.
Notes on Discretionary Disposable Income Index
scale: 0 to 100
100 * (income less housing costs) / max (income less housing costs) across all tracts
the smaller the index, the smaller the cumulative dollar discretionary buying power
