New Intercensal Population Estimates With 2010 Figures
The Census Bureau has released the intercensal estimates for the 2000-2010 decade. These estimates take the postcensal
estimates (the ones we have been using for the past 10 years) and have statistically revised them so that they
fit with the results of the 2010 census. See the Census Bureau's Intercensal Estimates web page for a detailed description as well as links to the data. These numbers are primarily at the state and
county levels with a few special files at the nation level. They provide demographic detail by age, sex, race and (Hispanic) origin.
The MCDC has downloaded most of the nationwide data files and stored them in the new intercensal20xx data directory within our public archive. We created three data sets here, all with state and county level summaries for the entire U.S. They differ only in the demographic detail available within each data set. You can also find the original csv files that we downloaded from the Bureau's web site and were the source of the three data sets.
New Web Application Displays Population Trends Using Intercensal and/or Postcensal Estimates
We have created a new variation on our popular Poptrends dynamic web application. The new poptrendspi20xx application looks at trends over the decade from 2000 to 2010. Users can select the time periods of interest, the demographic detail (age, race, sex and origin) wanted, the states and/or counties and the estimate type (intercensal and/or postcensal). By choosing to look at both estimate types the reports are a good way to get a handle on how good the old (postcensal) estimates were.
Here is a snippet of what a generated report looks like:
(Click here to see the complete report.) The report uses a scrollable table object where the column headers remain fixed on the page as you scroll up and down
using an Internet Explorer-only browser feature. (It still displays and scrolls with Firefox but the headers do not remain fixed.)
Even if you have no interest in comparing post vs intercensal figures the application lets you see trends over the decade includeing a
new estimate for July, 2010 (intercensal only).
Vintage 2010 American Community Survey Data Now Available
The Census Bureau has released the first set of summary data based on the single year 2010 surveys. These data are available for geographic
areas with at least 65,000 population. These are basically the same kind of data that we have been getting since 2006. As usual, we have
created a new data directory in our public archive to hold these "vintage 2010" data. Access via uexplore at http://mcdc.missouri.edu/cgi-bin/uexplore?/pub/data/acs2010 .
The files we downloaded and converted in previous cycles with the Bureau's profiles data were not available this cycle from the Census Bureau. This has required us to do considerable recoding to create our critically important usmcdcprofiles data set. We urge you to use these data with caution until we and our users have had a chance to use and review these data in depth. Please report promptly any problems you encounter with the data.
The same data stored in the usmcdcprofiles data set is used by our ACS Profiles web application (http://mcdc1.missouri.edu/acsprofiles/acsprofilemenu.html) where the default Period is now 2010.
The 2010 vintage detailed (or base) tables released by the Bureau are accessible within the basetbls subdirectory of the acs2010 data directory. The setup is the same as we have used for the past several years. A Readme.html file and a Varlabs subdirectory with detailed table outlines are must reading for users wanting to access these data sets for the first time.
The data can also be accessed at the Census Bureau's American Factfinder2 web site.
For users who are not familiar with the American FactFinder survey we strongly recommend that you first visit our American FactFinder home page for an orientation.
