A Feast for Geeks: Maricopa’s Post-Election Data Cornucopia

The latest Election Data Dispatch from my friends at Pew looks at post-election data from Maricopa County, AZ. The Dispatch itself (and the graphic above) focuses on the partisan distribution of provisional ballots rejected for lack of ID. While the conclusions to be drawn are likely as small as the sample size, the results – which show that Republicans and Democrats were equally likely to have had provisional ballots rejected for lack of ID – is somewhat counter to conventional wisdom and suggests that more research may be necessary to capture the full effect of ID requirements.

What’s remarkable, however, is that’s just one tasty nugget in a bountiful feast of data included in the report. Maricopa’s 193-page General Election Review (a PDF of a PowerPoint) is almost literally jam-packed with fascinating insights about the election process. I can’t do it justice in the small space I have here, but consider that included in the report are facts and figures about:

  • + daily utilization of early voting (p. 46);
  • + analysis of voided ballots by voters’ decade of birth (p. 55);
  • + traffic to online polling place locators in 2008 and 2010 (p. 83);
  • + statistics on problem reports by type and time of day (p. 103); and
  • + survey data on wait times (p. 172).

It’s really a remarkable document – and one which other jurisdictions would be well-served to examine and emulate in their own operations. Kudos to Maricopa (and Pew) for sharing this data feast with the election world!
