SEATTLE (October 10, 2013)--Half of the states in the U.S. have joined a consortium anchored by the state of Kansas, compiling their voter registration lists at the end of every year to assess for matches.
Meanwhile, seven states are coordinating on another project that makes those assessments more frequently with advanced algorithms while also checking for deceased voters.
Election managers say the efforts are necessary, as outdated voter registration systems are unable to keep up with a society where people often move from state to state.
This year, the Kansas project identified some 5 million potential duplicate registrations across 22 states.
The seven-state project identified hundreds of thousands of registrations that need updating, including 23,000 people who were dead.
