Survey data from the CDC's National Immunization Survey-Adult COVID Module (NIS-ACM) tracks trends in COVID-19 vaccination status and intent. It provides weekly national-level and monthly jurisdiction-level estimates. The dataset was last updated by data.cdc.gov in August 2023.
Use Cases
- Analyze temporal trends in vaccination intent by modeling `Estimate (%)` against `Time Period` and `Time Type`.
- Compare vaccination confidence across demographic groups using `Group Name`, `Group Category`, and `Indicator Name`.
- Assess geographic variation in vaccine uptake by joining data on `Geography` and `Geography Type`.
- Evaluate statistical reliability of estimates for policy using `Sample Size` and `95% CI (%)` columns.
- Identify suppressed data points requiring careful interpretation using the `Suppression Flag`.
Strengths
- Includes statistical reliability metrics via `Sample Size` and `95% CI (%)` columns.
- Provides dual temporal granularity with weekly national and monthly jurisdiction-level views (`Time Type`).
- Offers demographic breakdowns through `Group Name` and `Group Category` columns.
Limitations
- Sample size and total row count are unknown, limiting assessment of statistical power.
- Data may exhibit geographic bias if survey coverage is not uniform across all `Geography` types.
- The latest update was in August 2023, potentially missing recent trends.
