Web Applications
- MABLE/Geocorr (Vers. 3)
This "Geographic Correspondence Engine" allows you to access the Master Area Block Level Equivalency database
in order to see geographical relationships among a wide assortment of geographic units. For example, you can
see how ZIP codes correspond to county codes, or how census tracts relate to Public Use Microsample Areas ("PUMA"s).
The application will also let you select geographies within a specified radius of a point and aggregate the
population or housing units (1990) within the circle(s).
- Basic Tables for US With Menus
The MSCDC has been making these "Basic Tables" profile reports (based on the 1990 census
Summary Tape File 3 tabulation) available in various forms (starting with a Gopher
application in 1993) for several years. But now (1999), we have finally gotten around to
making it available for all parts of the US (not just Missouri and the
nearby states); in the preferred HTML table format (with plain text still an option); and now with a completely
menu-dirven interface so you
don't have to look up and enter any geographic codes. (As with the following application).
- Basic (1990 Census) Tables
  (Without Menus)
If you know your geocodes you can enter them on the form provided by this application and it will dynamically
generate a 1990 "Basic Tables" demographic profile report for that area. Works for areas as small as block
groups (and for census tracts, cities, ZIP codes, etc.) for anywhere in the country. (This is essentially the same application
as the previous entry but without the menus.)
- Post-1990 Population Estimates
This application lets you select the exact geographic, age, race, sex and time-period dimensions for a custom
report or CSV file containing the Census Bureau's post-1990 population estimates. Data available down to
the county level, with summaries for the U.S, regions, divisions, states and metropolitan areas.
Latest estimates currently available are for July, 1999.
- Chart Components of Pop Change in the 90's (Missouri Only)
This application accesses the Census Bureau's data regarding population trends with components of change for Missouri during the
decade of the 90's. Data can be accessed at the county level and at various county-group levels (UM Extension regions, metro areas, regional
planning commissions, commuting zones). Typical use would be to generate a series of bar charts showing population changes by
county over time for a metro area or Extension Region. This is our first public application that makes use of the SAS/IntrNet software.
- American Fact Finder is
the Census Bureau's prototype web application for providing access to their data. It is being developed as the
primary tool for delivering (among other things) the results of the 2000 Census and the American Community Survey data. The prototype
provides access to Dress Rehearsal data for these, as well as to selected 1990 census and other data. (Java capable
browser required.)
- 1990 Census Lookup
This very popular application, written at the Lawrence Berkeley Labs and now running at the Census Bureau,
allows easy and flexible access to 1990 STF1 and STF3 tables for most levels of geography for the entire
country.
- CIESIN's DDViewer
This really cool JAVA application (there is a non-JAVA version available as well) allows you to generate thematic
maps using a wide variety of geographic units (counties, census tracts, block groups, etc.) The data
that can be mapped is familiar to MSCDC web site users -- it is the same data used in our Basic Tables
reports and stored in our data archive in the /mscdc/data/stf903x directory. Not only does this
application provide very nice looking maps incredibly quickly, but it also lets you put the data into
a spreadsheet-type window for browsing. Use it, for example, to get a quick report of median household
income for all tracts in a county. Some of the features are not obvious, so you have to spend a little time exploring.
