Notes:
This crosswalk covers only the states that updated district boundaries for the 109th Congress: Maine, Pennsylvania and Texas. The variable "afact_cd108_cd109" indicates the fraction of residents of a district of the 108th Congress who reside in a given district of the 109th Congress, while "afact_cd109_cd108" indicates the converse. These weights are based on the population structure of the 2000 Census.
