New York State County-Level COVID-19 Vaccination Counts

New York State county-level data reports daily counts of individuals receiving at least one dose and completing the COVID-19 vaccination series. The dataset is created by the New York State Department of Health from provider reports to state immunization systems. Data collection began on December 14, 2020, and this specific version was archived as of November 10, 2023.

Use Cases

• Analyze vaccination rollout speed by comparing `First Dose` and `Series Complete` counts over time using the `Report as of` column.
• Identify regional disparities in vaccine uptake by aggregating `First Dose` totals per `County` or `Region`.
• Model county-level vaccination completion rates as a function of time using the `Series Complete` and `Report as of` fields.
• Track daily vaccination progress for specific counties by filtering the `County` column and plotting the `First Dose` time series.

Strengths

• Data is reported daily, providing a high-frequency time series for analysis.
• Covers all 62 counties in New York State, offering complete geographic coverage within the state.
• Data sourced from authoritative state immunization registries (NYSIIS and NYC CIR).

Limitations

• Dataset is archived and not updated after November 10, 2023, limiting analysis to historical periods.
• Excludes vaccinations administered by Federal entities or outside New York State, creating a coverage gap.
• Residency information is self-reported, which may introduce inaccuracies in county-level attribution.
