Voting has been around since Ancient Greece with the show of hands.  Now there are voter lists and using these lists can help bridge the gap between census and help with those more recent years where census records have not been released.

Some voter registration lists have been digitized and indexed which makes it easier to search versus having to search by voting precincts.  The content in voter registration lists varies from year to year and location by location.  Some lists contain age, address, occupation, political affiliation, date and place of naturalization.

To find out if a voter registration list is available for a geographical area, check in the 2 Volume set of Census Substitutes & State Census Records by William Dollarhide.
