Pennsylvania COVID-19 Confirmed and Probable Cases by Zip Code

Pennsylvania zip code-level data aggregates confirmed and probable COVID-19 cases, representing unique individuals. The dataset is provided by data.pa.gov and was last updated in July 2025, though weekly updates have concluded. It includes only valid Pennsylvania ZIP codes, with small counts suppressed for confidentiality.

Use Cases

• Analyze spatial distribution of COVID-19 using the Georeferenced Latitude & Longitude and Post Code columns.
• Compare case severity by region using the Confirmed and Probable case counts aggregated by Pennsylvania County Boundaries.
• Model case rates per zip code using the Post Code column as a key for joining with demographic data.

Strengths

• Includes confirmed and probable case counts per zip code.
• Provides geospatial coordinates (Georeferenced Latitude & Longitude) for mapping.

Limitations

• Small case counts (1-4) are suppressed and displayed as null, limiting granular analysis.
• Data is limited to Pennsylvania ZIP codes only, restricting broader geographic studies.
• Negative test results are no longer reported, reducing utility for calculating test positivity rates.
