Data source information:
June 1, 2007
Unit of observation:
369,211 individuals/registered voters
Households in the state of Michigan. Households with three or more registered voters were eliminated as were precincts with fewer than 100 voters. Households were eliminated that had been shown their vote history in previous field experiments as well as households where addresses listed on the QVF did not appear to be valid. The final sample was restricted to voters who voted in one of the previous two elections (2005 or 2006).
Voters were grouped into households, which were defined to include everyone with the same last name at the same address. Households were randomly assigned to either the control group or one of three treatment groups described next. Precincts were first given a random identifier and sorted in random order. Within precincts, households were sorted according to an arbitrary household identifier. These households were then randomly assigned into one of three treatment conditions using a skip pattern.
Mailing; Individuals assigned to treatment groups were sent one mailing 14 days prior to the November general election. There were 3 conditions: Civic Duty, Shown Past Abstention, and Shown Past Vote.
