Voter participation is reported below in two ways: the number of registered Voting Age Population and the number of those registered who voted.
- Voting Age Population (VAP) refers to the population over the age of 18.
- Voters Registered refers to the number of registered voters.
- Voter Turnout refers to the total votes cast for the highest position on the ballot.
The number of people registered to vote in Larimer County is a dynamic number that is constantly changing as people move in and out of the County and voters are placed in inactive status for failure to vote. The highest number of registered voters occurs just prior to the general election and is usually lowest after general elections when nonvoters have been changed to inactive status. For purposes of this analysis, the number used was the one taken prior to election day and includes active and inactive status.
As of June 2007, C.R.S. 1-8-104.5 established permanent mail-in ballot status. It is possible that the number of registered voters, beginning with the 2008 general election, will increase because of this law.

What the above data tell us:
From 2004 to 2010, Larimer County and Colorado had a higher percentage of registered voters compared to the United States as a whole. It is possible, however, that the method for calculating the number of registered voters differs between the national, state, and county levels.Often the number of registered voters increases in presidential election years (2004 and 2008) and that trend was more pronounced at the county level than the national or state level.
Although the data represented above depicts the percentage of registered voters who voted, it should be noted that over the last four general elections, the percentage of those eligible to vote varied from a low of 52.4% in 2006 to a high of 72.7% in 2010.

What the above data tell us:
In 2008, the ballot contained a large number of initiatives and long lines at the polling places were anticipated. The Secretary of State encouraged voters to request mail-in ballots and it appears voters in Larimer County heeded that advice. In 2010, the trend for voting by mail continued.It should be noted that in Larimer County voters no longer vote at a precinct polling station determined by their residential address. Started in 2003, residents may now vote at any designated County Voting Center.
Absentee voting involves having a ballot sent to your home rather than going to a precinct voting center to vote. Provisional ballots are ballots that allow a person to vote even though his or her name is not on the official voter registration list. In Colorado, individuals must first sign an affidavit to vote with a provisional ballot.
