All: 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.
