FairVote2020 has developed an interactive map showing turnout of the voting age population in Colorado for the 2000 presidential election. Additional maps include census data on race, ethnicity and income. Change maps by clicking on the map under "Compare Maps" on the left. You may zoom in on the map by clicking on the appropriate button at the top and then on the map.
The 2000 precinct lines and current Congressional, State House, and Senate boundaries can be turned on and off by checking the appropriate box below the map image. The precinct boundaries and congressional lines are checked by default.
At the end of this page is a link to Adobe maps showing nonvoters and 2000 turnout rates by precinct for Colorado localities with populations greater than 10,000. There is also a link to a second set of maps for the same places displaying Bush-Gore by precinct. Use the two sets in tandem to help target your canvassing efforts.

Turnout in 2000 Presidential Election (by 18+ pop)
Google-FairData Base Map (start with a Google map interface)
Map 1 -- Percent Turnout in Colorado (2000 election by 2000 precinct)
At a scale of about 5 miles, the number of voting age persons (by precinct) who did not vote in the 2000 election is displayed in purple boxes. This number includes both registered and unregistered persons and has not been adjusted for non-citizens. Precinct boundaries are those in effect in 2000.
Vote totals are estimates based on a block-level disaggregation performed by the Colorado legislative redistricting office. The methodology used to make block-level adjustments for early and absentee voting is described here.
At a scale of about 3 miles, pie charts display in areas with significant minority population, showing race/ethnicity components for the over 18 population.
Note: This map was modified on June 26, 2004 to show turnout based on voting age population rather than registered voters. Turnout based on the 18+ population more accurately reflects voter participation where voter registration counts appear to be overstated. Colorado's 2000 redistricting file shows 2.75 million registered voters, compared to the Census Bureau's more accurate survey estimate of 1.95 million in 2000.

This modification makes the Colorado map consistent with FairVote2020 maps for other states where we do not have post-2000 political data.

Community-wide Turnout Maps
Birds-eye view of turnout for the 18+ population in the 2000 general election. The numbers displayed in purple boxes show unregistered 18+ and non-voting registered voters by precinct, i.e. everyone over 18 who did not vote. These maps match the default map in the interactive map described above.
Community-wide Bush-Gore Maps
Bush-Gore by precinct (head to head contest excluding third party candidates). The numbers in boxes show estimated votes cast for the two major party candidates.
