CHAS 2000 data, a special tabulation of Census 2000
data created specifically for those involved in the
Consolidated Planning process, are now available on
HUD USER.

These CHAS (Comprehensive Housing Affordability
Strategy) data are useful to local government
officials and local housing planners for their own
planning processes, and to HUD officials who use these
data in allocation formulas for distributing funds to
local jurisdictions.

The CHAS data are different from standard Census 2000
data files, because they are mostly comprised of a
variety of housing need variables split by HUD defined
income limits (30, 50, and 80 percent of median
income) and HUD specified household types.

The data have been available since September 2003, but
updates were recently made that correct problems in
some of the tables. These data reflect new tables
created by Census at the minor civil division,
consolidated city, place, county, and state geography
levels. The updates make it easier for some
jurisdictions to compare 1990 and 2000 data.

The CHAS 2000 data have been changed slightly from the
CHAS data available in 1990. Variables that were
minimally useful were dropped. Three other
signification changes were made, including:

o Most of the variables are produced at multiple
geographic levels, including state, county,
minor civil division, place, and Census tract,
instead of at the geographic level of place and
county, as this information was available in
1990.

o On a select set of tables, HUD has added some
new income breaks to reflect programs with
different income requirements.  Those new breaks
include less than 21% of HUD Area Median Family
Income (HAMFI), 60 to 65% of HAMFI, and 95 to
100% of HAMFI.

o On a select set of tables, tenure is split three
ways:  rent, own with a mortgage, and own
without a mortgage. Tenure only split in two
ways in 1990:  rent and own. In addition, one
table splits the renter tenure by single-family
property and multifamily property.

The CHAS 2000 data are available in several different
ways. Users can engage a simple query system to gather
basic housing need and basic affordability data, or
they can download the data for just a particular
state. The data are also available at a national
level.

In addition to the CHAS 2000 data, HUD is also making
available data being used for various allocation
formulas, including the Indian Housing Block Grant
(IHBG) and Fair Share formulas.
