As most of you know, the USA conducts a full headcount every ten years in order to fairly apportion the seats of the US House of Representatives, as well as the seats in all of the other legislative bodies at all levels except for the USSenate (each state gets two seats).
The early estimates of what the Census Bureau will find include big gains for several traditionally politically 'red' states and more losses for the 'blue' ones.
for an interesting discussion on this.
In that article, Texas is expected to gain 4 seats, going from 32 up to 36 seats, Arizona will gain 2 (going up to 10 seats) with Florida, Georgia, Nevada, Oregon, South Carolina and Utah all gaining one (which kind of blows away the 'compromise' being pushed by those favoring the current proposal to give the DC delegate a full floor vote - and the article makes no mention of what state's seat would be 'on the bubble' this time).
The big losses would be mostly in traditionally politically 'blue' states and in states in the midwest with Ohio losing two seats (going down to 16 seats) and Illinois, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York and Pennsylvania all losing one.
As in 2000, California stays stable at 53 seats.
There are also some good comments in that NPR link.
