Communities at Risk Register: Flood Danger Scores for Wales

A standardized register ranking Welsh communities by comparative flood risk from High to Low. The methodology calculates a theoretical 'danger score' for both natural and mitigated scenarios, supported by a GIS layer defining community polygons. This dataset is provided by the Government Digital Service under an OGL-UK-3.0 license.

Use Cases

• Prioritizing flood risk management activities based on the comparative community danger scores.
• Analyzing the impact of existing flood defenses and warning systems based on the mitigated scenario scores.
• Mapping community-level flood vulnerability using the attributed GIS layer polygons.
• Conducting standardized, Wales-wide risk comparisons across all flood sources.

Strengths

• Applies a standard methodology across all flood sources for consistent Wales-wide comparison.
• Provides risk scores for two distinct scenarios: a natural 'undefended' state and a mitigated state.
• Includes a complementary GIS layer with attributed danger scores and community rankings.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and file size are unknown, which may limit suitability assessment.
