From census tracts to ZIP codes, AskCHIS™ Neighborhood Edition goes granular.

AskCHIS Neighborhood Edition (NE) is an online data dissemination and visualization platform that provides health estimates at sub-county geographic regions: census tract, ZIP code, city, county, and legislative district levels.

Using a sophisticated modeling technique called Small Area Estimation (SAE), AskCHISNE provides local health departments, policymakers, legislators, community organizations, researchers, and other stakeholders the data needed to target health interventions based on a neighborhood’s specific needs.
