2010 Official Apportionment Analysis

Released December 21, 2010 --

As part of our on-going reapportionment studies, we have released a series of tables based on the new final 2010 Census data released by the Census Bureau on December 21, 2010. The tables are:

1) Apportionment calculations using final apportionment populations and showing total seats for each state, the change from 2000, and state positions (seat numbers & populations by which seats were lost by or gained by). Labled Appendix Main

2) Same table as #1, only based on residence population only (ie, military overseas numbers pulled out). Unlike 10 years ago, there is no change. Labled Appendix A

3) Electoral College recalculations for the 2008, 2004 and 2000 election results using new apportionment population. Labled Electoral College Outcome

4) Historical Apportionment Table, showing number of Congressional seats given each state for each census from 1789 to 2010. Labled: Congressional Apportionment 1789 - 2010.

5) Ideal district size calculations for all states for Congressional, State Senate & State House districts.

6) Table showing impact of 2010 elections on redistricting of Congressional Districts, based on new apportionment results. Number of districts to be drawn in states under total Republican, Democratic, or Split control

2009 Reapportionment Analysis Released by EDS

Friday, October 01, 2010 New Census Bureau population estimates released today show new changes are likely for three more states in their congressional representation, with major emphasis on loses in the Midwest and gains in the South and Far West, compared to last year's population release. However, trends contained in the new data point towards more twists in population growth over the remaining nine months between the date of the data and Census day on April 1, 2010. The trends lead to a variety of potential scenarios by the time apportionment happens in 2010.

2008 National Voting Equipment Report

Tuesday, November 11, 2008
For the first time in the nation's history, fewer jurisdictions and less registered voters will be using electronic voting equipment than in the previous election. After nearly three decades of consistent growth in their use with each election, nearly 10 million fewer registered voters will be using electronic voting equipment in the 2008 general election compared to just two years ago.

Every county that has changed voting systems since 2006 has moved to optical scan equipment.
