BISD Board Demographic Study for Board Districting

Overview of the Data Presented...

The redistricting plan approved by the BISD Trustees on May 31, 2012, Plan 5F, is presented here.  This plan is being submitted to the Department of Justice and, when approved, will be used when the next BISD elections are held in spring 2013.

Also presented here is what the Department of Justice refers to as the “Benchmark.”  The Benchmark is produced by applying data from the 2010 Census to the current district boundaries.

Note that there are five files for both the proposed plan and the Benchmark.    

There are two map files.  The map files with names containing “8x11” are formatted for standard 8.5” x 11” paper; the map files with the designation “36x48” are formatted for 36”x 48” printers.  Note that the Benchmark is based on the precinct map used in the last BISD election.  The plan approved by the BISD Trustees is based on the precinct map adopted by Jefferson County in spring, 2012.

There are three sets of data files.  The first of these, labeled “Plan Statistics,” contains data used to confirm the plans conformity with the one-man-one vote doctrine.  These data include the number of persons in the “ideal” district, the number of persons in each of the actual districts, the difference between the ideal and the actual, and the computation of the index (called the Relative Overall Range) used by the Department of Justice to see if the plan meets their standard.  Plans with Relative Overall Ranges below 10.0 are considered acceptable.  Note that these computations are based on the Total Population (rather than the Voting Age Population) of the districts.

The files labeled “District Summaries” contain data regarding the racial/ethnic composition of the districts within each plan.  These data are used by the Department of Justice to consider “Retrogression.”  Note that these data are based on Voting Age Population.

Last, the files labeled “District Reports” include precinct by precinct breakdowns of the trustee districts.
