In 2002, Congress passed the Help America Vote Act (HAVA), which required each state to create a statewide voter registration database. California now has a centralized voter database, which links to county voter registration databases. As a result, overall data about voter registrations is automatically fed into the statewide database at the Secretary of State's office. The database currently does not have the capability of tracking the number of new or duplicate registrations coming from the specific categories listed above. Therefore, counties must track this data separately and report it to the Secretary of State.
*Voters may be placed on "inactive" status when an elections office receives information (for example, from the post office) indicating the voter has moved and the voter has not responded to an elections office request for address confirmation. For more information on state law "change of address" and "inactive" status procedures, see California Elections Code, sections 2220 to 2227.
