Los Angeles County

In this study we examine over- and undervotes from the November 2000 General Election in Los Angeles County. Los Angeles County is the nation's largest election jurisdiction and it used a punchcard voting system in that election. We use precincts as our unit of analysis and merge the 2000 election data with census data and voter registration data; our dataset allows us to examine all of the countywide races in 2000 (including candidate and ballot measures).

Absentee voting is becoming more prevalent throughout the United States. While there has been some research focused on who votes by absentee ballot, little research has considered another important question about absentee voting: Which absentee ballots are counted, and which are not? Research following the 2000 presidential election has studied the problem of uncounted ballots for precinct voters, but not for absentee voters.
