Deteriorated Paint Index: Predicted Lead Risk by Census Tract

The Deteriorated Paint Index (DPI) dataset from the U.S. Department of Housing and Urban Development predicts areas at risk for residential lead exposure. It uses household-level data to identify census tracts with many pre-1980 homes likely to have large areas of deteriorated paint. The data was last updated on 2026-03-11.

Use Cases

• Prioritizing remediation funding based on predicted risk of deteriorated paint.
• Identifying neighborhoods at high risk for lead dust exposure for intervention efforts.
• Modeling the correlation between housing age and environmental health hazards.
• Supporting policy decisions for local healthy homes programs.

Strengths

• Data is produced by the authoritative Department of Housing and Urban Development.
• Specifically designed to target limited remediation funding effectively.
• Last updated on 2026-03-11, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description does not specify the exact data sources or modeling methodology.
