Draft California Environmental Health Screening Results

Draft CalEnviroScreen 5.0 results identify California communities disproportionately burdened by pollution, incorporating recent census geography and data. The dataset includes indicator scores and percentiles, introducing two new indicators: Diabetes Prevalence and Small Air Toxic Sites. It is produced by the Office of Environmental Health Hazard Assessment (OEHHA) and was updated in March 2026.

Use Cases

• Map community-level pollution burden using indicator scores and percentiles to identify environmental justice hotspots.
• Analyze the correlation between the new Diabetes Prevalence indicator and other environmental health metrics.
• Assess the impact of Small Air Toxic Sites on overall CalEnviroScreen scores across different census geographies.
• Validate the refined methodologies for calculating indicator percentiles against previous CalEnviroScreen versions.

Strengths

• Includes two newly introduced indicators: Diabetes Prevalence and Small Air Toxic Sites.
• Uses the most recent census geography and incorporates the most recent data available.
• Methodologies were refined with input from community-based organizations.
• Data is provided in multiple formats including CSV, GeoJSON, and KML for flexible analysis.

Limitations

• Data is a draft version; final results will be posted after a public comment period.
• Specific row count, column count, and sample size are not provided in the input.
• Geographic coverage is limited to the state of California.
