A daily snapshot of mail ballot requests for the 2026 Pennsylvania Primary Election, extracted from the Statewide Uniform Registry of Electors (SURE) system. The dataset includes all processed applications, including those from permanent mail-in voters, and tracks ballot status, mailing, and return dates. Data is published for informational purposes, with county-level administrative practices leading to potential daily variations.

Use Cases

• Investigate reasons for ballot non-return or cancellation using Ballot status, Ballot status reason, and Ballot Application Disposition reason.
• Model voter party affiliation and age demographics using Party and Date of Birth columns.
• Map ballot request locations using Georeferenced Latitude & Longitude, Latitude, and Longitude columns.

Strengths

• Includes a deidentified voter ID to link multiple rows for the same voter, enabling longitudinal analysis.
• Contains over 20 columns detailing ballot lifecycle, voter demographics, and geographic districts.
• Data is extracted daily from the official SURE system, providing a point-in-time transactional view.
