Hat tip to Election Law Blog where I found links to the Electronic Assistance Commission’s press release and full report.

Key 2006 Election Facts (As reported by the states)
• Nearly 173 million persons were registered to vote for the 2006 elections—an increase of nearly 12.1 million since the 2002 midterm election.
• The number of registered voters declined since the 2004 Presidential election from nearly 176.2 million to 172.8 million.
• 76.6 percent of the Voting Age Population (VAP) was registered and 83.8 percent of the Citizen Voting Age Population (CVAP) was registered.
• More than 82 million ballots were cast or counted in the 2006 election.
• One percent of those participating cast a provisional ballot. (slightly more than 794,000 individuals)

The study also reports that the number of provisional ballots for 2006 was less than half of the levels reported for the 2004 election. However, a significantly larger share of the provisional ballots were counted. Only 64.5 percent of provisional ballots were counted in the 2004 election, compared to the 79.5 percent in the 2006 election. Nearly 30 percent of the jurisdictions across the country reported using multiple voting systems and the 2006 data show a dramatic rise in the number of jurisdictions using electronic systems. EAC’s 2004 study reported that just 9.3 percent of the jurisdictions reported using electronic voting equipment, but this increased to 53.6 percent two years later. The EAC survey found that 87.7 percent of the polling places allowed access for voters with disabilities, and 84.5 percent allowed these voters to cast a private ballot.
