* Note that the active registered voters count reflected above does include a small percentage of voters who are under 18 at present. Colorado law allows residents to register to vote as young as 16. Only active voters who are age 18 on or before Election Day will be mailed a ballot or able to vote.

To calculate voter turnout, excluding pre-registrants, or turnout by city or by party, review the return information provided here and compare using our Active Voter Registration Counts tool selecting voters 18 and older.
