The Wisconsin Elections Commission produces statistics on voter turnout and the number of registered voters. Additionally, the Commission produces reports of statistics prepared and reported by municipalities about elections, known as the EL-190.
Statistics on statewide voter registration prior to the 2008 presidential election are not available. It was not until recent years that Wisconsin developed its Statewide Voter Registration System, now known as WisVote. Prior to implementation of SVRS in 2006, not all municipalities were required to maintain voter registration lists. Requests for WisVote data such as voter lists should be made using the BADGER Voters website. More information on the data request process is available here: Data Request Process.
The Wisconsin Elections Commission has also revised the statement about data availability and quality to include information about election, voting, and registration statistics. These revised statements are included in the document attached below.
