The bill establishes a pilot program at the Centers for Disease Control and Prevention (CDC) to award competitive grants to up to 25 eligible entities. These grants will support the development or enhancement of neighborhood-level, publicly accessible health data platforms. The program aims to promote equitable access to local health data, integrate surveillance systems, and facilitate data-driven public health planning, with a focus on addressing health disparities. Eligible entities include State or local health departments and municipal or county governments, with priority given to those serving populations experiencing health disparities or lacking existing data systems. Grant funds can be used to develop platforms covering various domains like social conditions, housing, maternal health, and health outcomes, ensuring data disaggregation by neighborhood or ZIP code. All platforms must submit de-identified, aggregated data to a newly established National Neighborhood Health Data Repository , which will enable national comparability and provide visualization tools. The Secretary of Health and Human Services, through the CDC, will administer the program, providing technical assistance and evaluating its outcomes, including reports to Congress. An independent advisory panel will review the methodology for data aggregation in the Repository to ensure scientific best practices and privacy protections. The pilot program is set to terminate four years after its establishment.
