Public Law 94 2010 Census - References to Related Web Pages

Revised 3-3-11

  • We have created a series of state-based reports based on these data which can be accessed as follows:
    • Basic trend reports showing total pop, race and hispanic counts for 2000 and 2010 for various geographic units (currently just state, county and place summaries).

    • Comparison Reports where we look at the differences between the Census Bureau's official FSCPE post-censal estimates and the PL94 counts. These reports provide you with information regarding which counties may have been over- or under-estimated. The reports use "traffic lighting" (i.e. color coding of data cells) to highlight differences that are significant (4% or more difference). These difference should be of particular interest to users of American Community Survey data since those data are all adjusted to conform to the estimates. So when we see that the City of St. Louis has a population that is over 8% lower than was estimated we might want to take this into account when using any of the counts for the city in the ACS data, as they are also liable to be too high.

    • Last, and perhaps least, since we expect less user interest in these reports, are the VTD-Block hierarchal reports. These are pdf files, while all the others mentioned here are in html format. We are only planning to do these for Missouri and selected adjacent counties in Illinois and Kansas. There is one file/report per county and you will need to know the county code to select a county from the index. (See our geographic codes lookup app if you need to look up a code).

  • See data (at the state, county and tract levels for the entire country) mapped and displayed interactively using the New York Times Census Map application. Note that you can zoom in on the map and get census tract-level data once you are in close enough. It contains trend data comparing 2000 and 2010 data. This is an awesome application!

  • Additional Data: To access data from multiple geographies within a state, such as census blocks, tracts, voting districts, cities, counties and school districts, visit American Factfinder:

  • Visit the Census Bureau's Redistricting Data home page.

  • Use Uexplore/Dexter to access comparable data from the 2000 census in filetype pl942000.

  • To view dynamic maps displaying county level data see (May not be there for very long.)

  • As of 2-21-11 we have not finalized our plans for any online data products based in these PL94 data. But we have created a series of simple trend reports at the state, county and places levels for each state that can be accessed here (

    We have also created a prototype of a potential products similar to one we did for the 2000 data. View these hierarchal reports (for selected test areas in the states of Illinois and Virginia for now) here.
