At least every 60 days, each member submits their voter registration data and licensing and identification data from motor vehicle departments (MVD) to ERIC. ERIC refers to these data as Member Data. ERIC’s technical staff uses sophisticated data matching software to compare Member Data from all member states, sometimes with data from other sources, to create the following four “list maintenance” reports.
Cross-State Movers Report: Identifies voters who appear to have moved from one ERIC member to another using voter registration data and MVD data.
In-State Updates Report: Identifies voters who appear to have moved within the jurisdiction, or who recently updated their contact information, using voter registration and MVD data.
Duplicate Report: Identifies voters with duplicate registrations in the same state using voter registration data and MVD data.
Deceased Report: Identifies voters who have died using voter registration data and Social Security death data known as the Limited Access Death Master File and MVD data.
In addition, ERIC offers three other reports:
Eligible but Unregistered Report: Identifies individuals who appear to be eligible but who are not yet registered by matching voter registration data against MVD data.
National Change of Address (NCOA) Report: Identifies voters who have moved using official data ERIC licenses from the US Postal Service.
Voter Participation Report: For each federal general election, members can request reports identifying voters who appear to have voted more than once in the member jurisdiction in the same election, in more than one member jurisdiction in the same election, or on behalf of a deceased voter within the member jurisdiction.
Simply put, ERIC compares a member’s voter records to other members’ voter records, MVD records, and to federal deceased data and national change of address data, for the purposes of flagging differences that indicate a member’s voter record may be out of date or inaccurate.
