This is the first year since I became interested in politics that the concept of redistricting has been used. I'm still a little confused on the process, so if anyone could clarify for me, I'd appreciate it. I just have a couple questions.
First, when is the redistricting going to take place? In November 2010, representatives will still be elected from the current congressional districts, right? I'm assuming they will go into effect for the 113th Congress (2013-2015)? Also, does the redistricting process take place on the same day (do all the state legislatures do it on the same day)? I guess the question I'm asking is when will we know the new congressional districts?
Also, is there any data out there right now as to what states will gain/lose seats and which ones will stay the same? Someone on here (believe his name is muon2) has a neat little diagram as his signature on here; was just wondering how people come up with that. I know it's based upon population but was just curious if there's a website out there that shows the forecast/most likely seats/district each state will have.
Sorry for the confusing questions and thank you to anyone who answers them for me
I'll take the second part of the questions first. Reapportionment is the process that sets the number of seats each state will have for the next decade. It's based on the Census info collected this spring and will be made public before Dec 31. The map in my signature is one projection of which states will change based on Census Bureau estimates from July 2009. If you follow the link in the signature you can read more about the methodology, as well as see an alternate calculation I made with slightly different assumptions about population growth in 2009.
In the first three months of 2011 the Census Bureau will release detailed data down to the block with total population, age and racial/ethnic makeup. This is the redistricting data set that is the basis for all new districts from Congress down to local wards. Most states will draw their districts during 2011 to be ready for the 2012 primaries.
The states vary widely on the means to draw Congressional districts. Most do it as a matter of statute from the legislature, signed by the governor. There are a number of states that use independent commissions, and many create commissions to deal with failure by the legislature. Quite a few new maps will end up in the courts, and if the past cycles are repeated at least a couple will go all the way to the SCOTUS and result in new interpretations that everyone will be using in 2021.
