Travis and Bexar Counties both keep their current allocations of six and 10 legislative seats, respectively. Williamson County, however, expands from 1.8 to 2.43 seats.
Also, growth in Hays County has been explosive. Hays goes from 0.70 to 0.92 seats. Right now, Hays County is just below the threshold to become its own district, and the Census estimate shows 53 percent growth in the county since the 2000 census. According to the census, Hays and Blanco are the only constitutional combinations of counties that could form a state house district under a new map, but if growth trends continue, it is likely that Hays County will be its own state house district in the 2011 redistricting map. (If the county population gets within five percent of the ideal district size, the Texas constitution requires that it become its own state house district).
Waco could pose another set of problems for map drawers. McLennan County goes from 1.54 to 1.42, according to the census estimate. That means the district currently held by Rep. Jim Dunnam (D-Waco) is at about 0.9 as it is currently drawn and would have to pick up additional counties.
