Methodology

The Election Integrity Index (eii) is a composite score from 0 to 100 that aggregates reported election integrity incidents within a geographic area. Higher scores indicate more reported concerns.

The formula weights incidents by evidence tier:

Incident types are weighted by severity. For example, ballot stuffing (weight: 2.5) contributes more to the score than campaign finance violations (weight: 1.0).

Verified Incidents: Court records, DOJ Public Integrity Section prosecution data, state attorney general press releases on election crime convictions.

Alleged Incidents: Active lawsuits tracked by Democracy Docket, state election board complaints, EAC EAVS rejected ballot data, statistical anomaly reports.

Unverified Claims: Aggregated public claims lacking supporting evidence, including debunked allegations retained for transparency.

The map uses three zoom levels:

• National View (zoom 3-6): States colored by aggregate eii score. Click a state to zoom in.
• State View (zoom 7-9): Counties within the state become visible, each colored by their county-level eii score.
• County View (zoom 10+): Individual incident markers appear at reported locations, colored by evidence tier.

State and county boundaries come from the US Census Bureau TIGER/Line simplified shapefiles (1:10M scale).

• Coverage varies by state. Some states have more comprehensive public records than others.
• The eii score reflects the volume and severity of reports, not a determination of whether fraud occurred.
• Unverified claims are included for transparency but may be inaccurate or debunked.
• Data is aggregated from multiple sources with varying update frequencies.
• Community votes on score accuracy are advisory and do not change the underlying data.
