Caliper Corporation has just made available to its users the Adjusted 2000
Census Data. These data contain PL94-171 redistricting data, adjusted based
on the Accuracy and Coverage Evaluation (A.C.E.) survey conducted during
Census 2000. The A.C.E. survey was designed to measure net undercounts,
such as people missed, and overcounts, such as people counted twice. The
undercounts are largely in Latino, African-American, and other minority groups.
We have created a web mapping application at
(http://198.22.17.155/maptitude/censusadjusted/map.asp?map=1) that you can
use to browse the difference and percent difference between the original
and adjusted total population, and the difference between the original and
adjusted Hispanic population. The map starts at the state level, and as you
zoom in shows the data at the county and then the place/MCD level. You can
locate a state, a ZIP Code, and even an address to move the map to an area
of interest, and you can click on map to get more detail on the Adjusted
2000 Census Data for an area.
Users of the Caliper Corporation Geographic Information System software
products, Maptitude and TransCAD, can purchase Redistricting Data CDs with
Adjusted 2000 Census Data, which are available for a single state or
territory. Each Data CD contains boundaries and adjusted 2000 Census data
for Block Groups, Blocks, Counties, County Subdivisions (MCDs), Indian
Reservations, Places, State, Tracts, and Voting Districts for a single
state or territory. For more information, please visit
(http://www.caliper.com/DataCDs/AdjustedData.htm).
We hope that you find the web mapping application a useful way to start
looking at the Adjusted 2000 Census Data.
