2020 Pennsylvania Primary Mail Ballot Requests With Voter District Data

2020 primary election mail ballot requests from the Pennsylvania Department of State. The dataset is a snapshot of request volume across the Commonwealth, with voter birth dates anonymized to 1/1/1800 for confidentiality, often for domestic violence victims. It was published by data.pa.gov and last updated in July 2025.

Use Cases

• Analyze temporal patterns in mail voting by joining Application Request Date, Ballot Mailed Date, and Ballot Returned Date.
• Model Applicant Party Designation distribution across Congressional District, State Senate District, and State House District.
• Examine processing timelines by calculating intervals between Application Request Date, Application Approved Date, and Ballot Mailed Date.
• Profile County Name variations in Mail Application Type usage, including UOCAVA categories like Military (M) and Civilian Overseas (CVO).

Strengths

• Includes geographic granularity with County Name and multiple legislative district columns.
• Contains specific application type classifications for military, overseas, and other absentee voters.

Limitations

• Sample size and total row count are unknown, limiting statistical reliability.
• Birth date data (Date of Birth) is fully anonymized to a single placeholder value, removing age analysis.
