Understand health equity across Santa Clara County

Explore how health needs, access barriers, resources, and local conditions differ from one community to another.

Search Sunnyvale, San Jose, a supervisor district, or a census tract, and see its health equity picture.

View every tract ranked by combined concern, and understand what drives each ranking.

Put two tracts, cities, or districts side by side and see exactly where and why they differ.

Countywide snapshot

A small set of decision-relevant summaries, not a wall of metrics.

Public data only: Every number comes from federal, state, county, or transit-agency sources -- never uploaded or invented data.
No individual-level data: Every figure describes a neighborhood or aggregate group. Nothing here identifies or predicts an individual person.
Methods are always visible: Every score can be broken down into the exact metrics, weights, and sources that produced it.
Uncertainty is shown, not hidden: Margins of error, data gaps, and how sensitive a ranking is to assumptions are shown next to every score.
Screening, not causation: A high score means an area warrants a closer look -- it is not a claim that any specific program will fix it.
