California UCRI score story | scroll
01 / 05
58 counties. 9,129 California census tracts.
One statewide operating model, organized for county-scale orientation and full-resolution tract review.
02 / 05
Every record is linked to a 2020 California tract.
Stable 11-digit GEOIDs connect the map, scores, ranks, raw conditions, provenance, and reports.
03 / 05
Five documented signals retain their source context.
Canopy deficit, heat exposure, impervious surface, social vulnerability, and environmental burden remain inspectable below the composite.
04 / 05
UCRI = 0.25 CDS + 0.25 HES + 0.15 ISS + 0.20 SVS + 0.15 EBS.
California UCRI uses statewide percentiles and CalEnviroScreen 5.0 Pollution Burden for EBS.
05 / 05
1,810 tracts screen as Extreme.
Extreme is a relative category in the current statewide UCRI distribution, not an emergency or health-risk designation. Every highlighted tract remains traceable to the July 2026 release.
