Elections data sets for a variety of needs.

The ACE data sets can be used for a variety of purposes. Want to know broad statewide trends? Want to understand the differences in county election behavior? Want to track the elections activities of a specific county? ACE can answer each of these questions for the most sophisticated election administrator, as well as those simply interested in how Colorado elections work. Finally, Colorado has the tool to understand its elections – and in doing so, make them better.

Visualization for action

That’s where ACE’s interactive maps come in. ACE visualizes the data in several interactive maps. These give meaning to the numbers that spreadsheets and pie charts can’t. We know that data is only effective when it engages the user. So ACE visualizes the data in several interactive maps. These give meaning to the numbers that spreadsheets and pie charts can’t.

Transparency with purpose

As the first state in the U.S. to display comprehensive registration and election data in a single centralized online location, the Colorado Department of State creates the closest thing to true transparency between the government and its citizens.
