Five states — Arizona, Florida, Nevada, Texas, and Utah — would each gain one seat if the U.S. House of Representatives were reapportioned with census population estimates for July 1, 2005, according to an analysis by Election Data Services. Five states would lose seats — Iowa, Massachusetts, New York, Ohio, and Pennsylvania. In Election Data Services' 2004 analysis, only four seats changed. Nevada is an addition to the states gaining seats; Massachusetts, to the states losing seats. The 2005 population estimates, which have not been statistically adjusted for any known undercount, were released today by U.S. Census Bureau.
