The study compared lists of people in the state's ID database with its voter rolls. Officials found that a staggering 1.3 million of Pennsylvania's 8.2 million voters -- more than 1 in 7 -- didn't appear to have valid state IDs. In Philadelphia alone, the figure was 362,000 voters, or about 1 in 3.
Those numbers almost certainly exaggerate the sheer size of the problem; the Philadelphia Inquirer, for instance, raised serious doubts about the state's methodology after finding false hits for people with any form of punctuation in their names. But even if the scale of the numbers is off, their distribution shows troubling variances among the city's ethnically and racially distinct neighborhoods.
