Examining the Citizen Voting Age Population (CVAP)

The Citizen Voting Age Population (CVAP) is a measure of the total population who are both U.S. citizens and 18 years or older. It is tabulated annually as part of the American Community Survey (ACS) for geographic areas ranging from the United States to the lowest level block group. CVAP is crucial as it indicates the maximum potential number of registered voters in an area. The ratio of CVAP to the actual number of registered voters shows how many eligible citizens are not registered to vote. For areas where the ratio exceeds one (>1.00), voting rolls may need updating. Use the VDAGIS interactive mapping tool below to find CVAP data for specific census tracts and compare it with other demographic information.

Patterns of Percent CVAP Population by State
The graphic below shows the percentage of the Citizen Voting Age Population (%CVAP) by state from the ACS 2022 1-year estimates. State %CVAP ranges from 66.4% in Texas to 81.1% in Vermont, with the U.S. average at 72.4%. Click the map for a larger view.

Interactive Mapping -- Using VDAGIS to Examine CVAP by Census Tract
1. Watch the Video: Click here to see a video that explains the steps below.
2. Start-Up View: The initial view shows the U.S. 48 states by county.
3. Objective: Examine the percent CVAP by census tract.
4. Search Location:
    - Enter "15625 SW 80th St, Miami, FL 33193" in the search bar above the map.
    - Click the "Find Location" button. The map will zoom to this address.
5. Navigate the Map:
    - Use the buttons below the map to navigate.
    - To zoom, hold down left+shift and drag the mouse to draw a box.
6. Enable Layers:
    - In the legend panel on the left, scroll down and check "Tracts Code".
    - Scroll further down and check "Tracts %CVAP".
    - Click the + next to the layer name to expand the color/value intervals.
7. View %CVAP Patterns: The map now displays %CVAP by census tract in the selected area.
8. Get Tract Details:
    - Click any census tract to highlight it and display its profile in the lower left.
    - For example, click tract 12086017800 (at the marker) to see:
    - Population: 6,063 (D001TPOP — for those who know Census tables)
    - CVAP: 3,119
9. Calculate %CVAP: The %CVAP for this tract is (3119 / 6063) * 100 = 51.4%.
