Registering Re-entering Citizens to Vote [Texas]

Research questions: Can outreach to people with criminal records – a hard-to-find group based on traditional data sources – increase registration and voting behavior for this group? Is outreach to people in their social networks equally or more effective? 
Hypotheses: Providing information about voting eligibility and registration to people with criminal records or people in their social networks, using contact information from commercial vendors, will increase voter registration and turnout in midterm elections.
Intervention: We will match data from criminal records with contact information from a commercial vendor, to create a contact list that would be unavailable based on traditional data sources. We will then use this contact list to conduct a randomized controlled trial, sending mailers to those assigned to the treatment group or to people in their social networks (e.g. household or family members).
Sample size: Across all conditions and control groups, we expect a total sample size of 618,336 in this add-on experiment (108,428 treatment; 54,212 control). 
Outcomes: The primary outcome measures of interest are (1) voter registration, and (2) voter turnout in the November 2022 midterm election.
