Potential Voters Map

This map shows an estimate of the individuals who are citizens of voting age (eligible to vote) but not registered.

Each area is a census block group (between 600–3,000 residents).

Darker shades of red represent places with a larger number of non-registered voters.

Some of these areas include colleges and universities with student housing, such as Storrs where the University of Connecticut is located.

How to Use This Map

This map is designed to guide planning for voter registration and voter education efforts. It provides an estimate of the total number of individuals who are eligible to vote but not registered. Other available maps indicate which addresses do and do not have registered voters, but are unable to tell you if all eligible voters at an address are registered, or if anyone is eligible at addresses where no one is registered. This map can guide your overall strategy for registering all eligible voters in a given census block group.

The interactive map illustrates the difference between the estimated number of Connecticut residents who are eligible to vote and those who are actually registered to vote. Data is shown at the census block group level (areas of 600–3,000 people).

Block groups with darker shades of red represent places with a larger number of non-registered voters. Some of these areas include colleges and universities with student housing, such as Storrs where the University of Connecticut is located.

Hover (or tap) over areas to see the number of estimated and registered voters. If you are interested in exploring voter data for a certain location, you can also use the search tool in the upper-left corner to find addresses in Connecticut. 

About The Map

This map can be used to locate areas of low voter registration to identify areas of opportunity for voter registration efforts. We do not recommend using this map to report the absolute number of non-registered voters in a particular area, given geocoding limitations and sometimes high margins of errors of CVAP estimates.

Data on the 2.4 million registered voters in Connecticut comes from the Secretary of State’s Office. Voter addresses were geocoded (94.7% match) and then aggregated by census block group to calculate the difference between the number of eligible (estimate) and registered voters.

The estimated number of residents eligible to vote in each census block group comes from 2018 American Community Survey (5-year estimates) Citizen Voting Age Population (CVAP) dataset. The margins of error provided correspond to a 90% confidence interval.
