About 3.9 million people, or 3.0% of voters in states where party affiliation is reported, are registered under a minor party as of September 2026.

Seven states have recognized minority political parties that include “independent” in the name. In other words, independent minority parties are different from being a voter who is independent of a party affiliation.

Where does this data come from?
Where does this data come from?
Data collected in this article comes from state government election official sources. Each state has an official to oversee elections in the state — most often the secretary of state — and are administered by over 10,000 local jurisdictions. The US Constitution mandates election rule-making to state legislatures, but also allows the Congress to create election laws. Some states release voter statistics daily, monthly, quarterly, or less frequently than that. 2026 data is up to date as of the time of publication.
When possible, voter counts are “active” voters, a designation that changes from state to state. In Utah, for example, a voter becomes inactive when they “have not updated their address or who had mail returned as undeliverable.” In Michigan, a voter becomes inactive when they move from their voting jurisdiction, they die, they are identified as a duplicate, or the voter requests to cancel their registration. Inactive voters are typically ineligible to vote.
