GRID3 NGA - Operational Wards v2.0: Administrative Boundaries for 15 Nigerian States

Operational ward boundaries for 15 states in Nigeria: Adamawa, Bauchi, Bayelsa, Borno, Delta, Gombe, Jigawa, Kano, Katsina, Kwara, Niger, Ogun, Osun, Oyo, and Yobe. The dataset was produced by GRID3 and the Center for Integrated Earth System Information (CIESIN) at Columbia University, with a last recorded update in April 2026. It is considered operational and has not been fully validated by government officials.

Use Cases

• Mapping population distribution based on ward-level administrative boundaries.
• Planning resource allocation for health or education services using the operational ward units.
• Conducting spatial analysis for development projects within the 15 specified Nigerian states.
• Integrating ward boundaries with other demographic or survey data for localized insights.

Strengths

• Explicitly lists 15 Nigerian states covered, providing clear geographic scope.
• Data is associated with the GRID3 initiative and CIESIN at Columbia University, suggesting a reputable source.
• Available in multiple file formats, including GEOPACKAGE for geospatial analysis.

Limitations

• Dataset is described as operational and not fully validated by government officials, which may affect positional accuracy.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total number of wards are unknown, which may limit suitability assessment.
