Redistricting Data

People have been asking me for this so I might as well just put it up for all.  In general you can get the 2010 Redistricting data from the census yourself, but the census folks don't make it very easy these days.  Below are some links to data files with extracts for the city and county demographic data by voting district.  Basically the fodder for all the redistricing to come.

  • Extract of Allegheny County voting district demographics for 2010 in Excel online here 

  • Summary of those same 2010 demographics just for city of Pittsburgh voting districts matched to the file I have online of historic city of Pittsburgh election returns for selected races back to 1999. Again in Excel:  Online here.

Use. Enjoy. Wonk.

 
Postscript for the uber wonks out there.  In recent previous decades the Pennsylvania Legislative Reapportionment Commission (PLRC) would actually rework the census data before it was reissued for use in Pennsylvania redistricting.  The reason that was said to be necessary came from deficiencies in the geography of voting district data as was compiled by the census compared to the actual patterns of voter registriation as administered by counties.  Over the last decade the Census contracted a major reworking of all the boundaries of geographies within the state which apparently were very screwed up for Pennsylvania.  That rework supposedly minimized or eliminated the need for adjustments by the PLRC. I say supposedly only because I have not looked in detail at the changes made.  So the data for 2010 in the extracts above is straight from the Census and is not PLRC adjusted data.

The PLRC was permitted to rework the census data? I'm sure that no manipulation was ever done for political purposes.

Shame on me for being so cynical.

Should the heading on Column G of the Pgh data be "Census 2010"?
