Here are pertinent links for all of the competing maps and Council proposals:The Common Cause online program is helpful as it can be used to compare the various statistics for each of the maps.
--- R drawn maps
--- R ordinance
--- D drawn maps
--- D proposed ordinance
--- Common Cause DrawMarionCounty - R drawn maps
--- Common Cause DrawMarionCounty - D drawn maps
I did input all of the D drawn maps, and as a verification that I did so correctly, the population of each district matched exactly the numbers provided on the Council website.
I looked at both the political (R voters vs. D voters) generated with the Common Cause website, which uses 2008 voting data and which generates only percentages. There were two differences with the numbers provided on the Council website for the D drawn map - Council District 12 shows a Democratic majority on the Common Cause website, but a Republican majority on the Council site & Council District 3 was just the reverse.
Using the Common Cause website, the R drawn maps create 16 D majority and 9 R majority districts. The D drawn maps create 17 D majority and 8 R majority maps. The Common Cause website projects 19 D and 6 R districts in the currently used maps.
Of more concern, though, is the loss of Black majority voting age population districts.
Again, using the Common Cause website, the R drawn maps create 3 Black voting age population majority districts, the D drawn maps create only 2. Both are down from the current 4 districts.
Looking at the non-white minority voting age population districts, both the D and R drawn maps create such 8 districts. Currently there are 7.
