This should make quality control with other sources of Census
data rather easy, as long as other sources can tie to Census meta
data.

I am approaching the Census data from Zip+4 geography, I have tried to
select the closest Zip+4, based on latitude and longitude, to each of
the
8,262,363 census blocks(entire US, DC Puerto Rico). I can then match
the block data to internal customer lists based on zip+4. If a match
fails on the 9 digit Zip+4, I drop last digit and use zip+3 (
summarized record ), if that fails I drop another digit ...

The SAS matching software implements the drop last digit logic. You
can use the Zip level ethnic data ( 43,019 rows and 288 columns) and
the SAS software to concatenate ethnic data to your Zip level lists.

If anyone out there has a 100Gb of ftp space, I am willing to build
and
store the SAS data model and make the SAS tables available to all.
This model makes the raw Census 2000 counts easy to use.

I only ask that the site follow the free software/data GNU model.
