MABLE/Geocorr (Version Index)

April, 2017

These geocorr web modules allow the user to obtain geographic correpondence files (aka "crosswalk files", "correlation lists", etc.) for dozens of geographic layers for the United States (50 states + DC). The various applications are nearly identical in what they do, but vary in terms of the vintage of the MABLE datbase being accessed.

Select Version:  Click on the version name to be taken to that application.

  • Geocorr14. This is the current production version that works with the latest available data through 2014.

  • Geocorr12. This is an earlier version that works with 2012 vintage data. Why anyone would use this version instead of 2014 is a mystery to us but the stats show it is the most frequently accessed version.

  • Geocorr2k. This is the version that works with geography from the 2000 census (with some updated fields as recent as 2008).

  • Geocorr90. This is the version that works with geography from the 1990 census. This is the original.

Documentation Links


  • Each of these geocorr versions has its own link to a MAGGOT file. The Master Area Geographic Glossary of Terms pages provide brief descriptions of the geographic layers available for that version of MABLE/geocorr. (The link appears just below the Select State(s) box on the goecorr form).

  • The MABLE databases are almost entirely based on the Census Bureau's TIGER databases. These do not exist prior to 1990 and so there is almost no chance that we shall ever see a geocorr80 or geocorr70. But a geocorr20 is highly likely.

  • Each version of MABLE is based on its own set of census blocks (1990, 2000 or 2010). There is currently no version of geocorr that can work across these database to produce correlations across time. (So you can't use geocorr to create a tract-2000 to tract-2010 equivalency file.)

  • When doing large extracts (usually this means when doing all states at once) use the Output Options section to turn off the report file output. Generating such large html files wastes time and space.

  • For data geeks only: the MABLE databases are collections of state-based SAS data sets, that can be directly accessed using the MCDC's Uexplore/Dexter modules. Each state has 4 SAS data files with <stab>v (alv, akv, ...) being a SAS view that merges the other 3 together to give you all the geocodes at the block level for that state. Dexter can provide output in SAS data set and dbf formats as well as csv, html and pdf.
