A Critique of Barr, Cogggeshall & Zhao (2011)

In 2011, Joseph R. Barr, Stephen Coggeshall and Wenzhong Zhao of ID Analytics, Inc. produced a “White Paper entitled, The Trouble With Names, in which they calcuated that as many as 8.3% of Americans might coincidentally match other Americans with the same name and date of birth. But there are problems, both with their analysis, and with its application to voter identification:

EXCERPT:

  “The numbers of potential voter fraud cases revealed Wednesday were gleaned from a cross-checking of voter records among 28 states. It was the first time North Carolina participated in the cross-check process, which was required under sweeping new election laws passed last year by the Republican-controlled General Assembly.

  “Specifically, the check found 765 voters whose first and last names, dates of birth and last four digits of their Social Security numbers matched exactly with a voter registered in another state and who voted in both states in 2012. The results also identified 35,750 voters with matching names and dates of birth who voted in North Carolina and another state that year.”
