County-Level HIV Prevention Gap Index for the US Deep South, 877 Counties

A dataset of 877 counties across nine US Deep South states, created by Ruaa Al Juboori and last updated in April 2026. It contains a calculated Prevention Gap Index (PGI) derived from standardized HIV prevalence and three prevention/care proxies: PrEP utilization, viral suppression, and HIV testing site density. The data is used to examine spatial variation and associations with structural determinants like ethnicity and income.

Use Cases

• Identify counties with high HIV prevention gaps based on the calculated Prevention Gap Index for targeted intervention planning.
• Analyze spatial patterns and clustering of HIV burden and prevention proxies across the Deep South region.
• Model associations between prevention gaps and structural determinants like percentage of non-Hispanic Black population, income, and education.
• Validate the Prevention Gap Index by comparing its classification with federal Ending the HIV Epidemic (EHE) Phase I priority counties.

Strengths

• Includes data for 877 counties, providing a substantial geographic scope for the region.
• The Prevention Gap Index is validated against external benchmarks, showing moderate to strong differentiation of EHE priority and high-diagnosis counties.
• Analysis incorporates spatial regression models to account for geographic clustering, improving model fit.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the selected nine-state Deep South region.
