Irving ISD movement to 7 single member districts

The 2010 census made the need for ending the at-large Irving ISD board system obvious. While only 29.99% of the Irving ISD resident population is Anglo, and only 10.7% of IISD students are Anglo, there are no minority members on the 7-member school board.  Minority advocates have been pushing for a 7-0 single member district method for Irving School Board elections for years.  This history and current plans were spelled out with today's Dallas Morning News article on the maps released this week by IISD.  These maps presented two possible board configurations: a 5-2 configuration with two at-large positions remaining, and a 7-0 configuration where all members would be elected from single member districts.  Copies of these maps are available from

The 5-2 configuration would be a tragic, and potentially costly, delay in the movement toward a full and inclusive representation on the Irving ISD Board.  The following 12-15-11 draft of a 7-0 single member district map is the best alternative seen so far in the work for a more representative Irving ISD Board:

While the 7-district map created by the Irving ISD Board was a positive step in the right direction, the above map shows that significantly stronger minority representation is possible. 
  1. A plurality black voting age population District 3 is created in the above map that is over 4 percentage points stronger than the District 3 in the IISD created 7-district map. There is no district in any of the two IISD created maps wherein the largest racial/ethnic group voting age population in a district is the black population, but it can be done!
  2. The above map improves the potential for Hispanic representation. It increases Hispanic voting age population in District 6 by over 1.5 percentage points to 72.64%.
  3. Possibly the best improvement is that, while improving minority representation significantly over the IISD proposed maps, the above map also much more closely meets the 24,412 population target for each of the 7 districts. The one-person one-vote foundation for our nation's democracy can be more closely achieved.  A 10% range of deviation from the 24,412 target is allowed. The Irving ISD prepared map has a range of deviation of 7.68%. (Range of deviation is the sum of the largest district percentage above the target population plus the percentage below the target from the district most below that target.)  The above map not only improves minority representation, but also cuts the range of deviation in half, to 3.43%. 

This map is an example of what is possible as we build toward a final draft of a district map to present to the IISD Board in January. Hopefully the value of getting as close as possible to equal representation for all will be guiding the decisions made.  If you have any questions, or recommendations for improvement on this map, please email
