2004 Presidential Nomination Contest Turnout Rates

Last Updated: 10/08/08

Please note, this page is in the process of being updated. For the time being, I am making this legacy web page available.

In the table below, two estimates of the voting population are provided.  One is the VAP or "Voting-Age Population" and is an estimate of the number of persons age 18 and older residing in a state.  The VEP or "Voting-Eligible Population" is an estimate of the number of persons residing in a state who are eligible to vote.  These two numbers are not equivalent since non-citizens and ineligible felons (depending on state law) are included in the VAP but are excluded from the VEP estimates.  Although I highly recommend using VEP, I provide both numbers as a service to people who still rely on VAP.

These estimates of turnout may be different from many state Election Board statistics which report turnout as a percent of registered voters.  Registration numbers are not comparable across states or across time within the same state because state registration laws and frequency of purging of inactive voters from registration rolls vary.  However, the limitation to using these estimates as measures of primary participation is that they do not provide partisan breakdowns.

Data

All estimates are of the first of the month for a given election date.  Where possible, I provide a link to the source of turnout data for a given election.  Other useful links:

Notes: (a) Source: Personal communication with Kristin Scuderi, Communications Director, The Iowa Republican Party (1-23-04).  The Iowa Republican Party does not tabulate participation in uncontested caucuses, though caucuses were held in every precinct.  Attendance was reported for four counties: Black Hawk 540; Dubuque 347; Linn 1,350; and Polk 1,300; for a total of 3,537.  Republican caucus attendance averaged 9.1% of Democratic attendance in these counties.  Applying this percentage statewide, an estimated 11,160 Republicans attended caucuses.  This is likely an over-estimate since the reporting counties held events where well-known Republican officials spoke.
(b) Michigan Democrats selected delegates at a March 11, 2000 caucus where 18,791 people voted.
