HHS COVID-19 SAE: County-Level Vaccine Hesitancy Estimates

United States county-level small area estimations track monthly changes in adult COVID-19 vaccination hesitancy for the HHS 'We Can Do This' public education campaign. The dataset provides modeled proportions and standard errors for three population segments: vaccination enthusiasts, the target audience, and those not targeted by outreach. Columns suggest it is designed for temporal and geographic analysis of public health intervention effectiveness.

Use Cases

• Mapping county-level vaccination enthusiasm using enthusiast_est and FIPS.
• Analyzing uncertainty in target audience estimates using audience_est and audience_se.
• Tracking monthly changes in populations not targeted by outreach using no_outreach_est.
• Comparing relative confidence intervals across population segments using the various *_se columns.
• Correlating FIPS codes with external demographic data for spatial regression analysis.

Strengths

• Provides modeled estimates at a granular geographic scale (county-level) for the entire United States.
• Includes standard error columns (e.g., enthusiast_se, audience_se) for assessing estimate uncertainty.
• Data is hosted on an official government platform (datahub.hhs.gov), suggesting institutional provenance.
• Appears on multiple platform instances, indicating sustained relevance and use.

Limitations

• Critical metadata is missing: row count, dataset size, specific license, and author are not provided in any source.
• The description is repeated verbatim across all sources, indicating a potential lack of detailed documentation.
• The temporal coverage (time_range) for the estimates is not explicitly stated, limiting understanding of the period analyzed.
