IDU: Daily Internal Displacement Flows in Mayotte

Mayotte conflict and disaster population movement data provided by the Internal Displacement Monitoring Centre (IDMC). The dataset offers provisional, daily-updated estimates of new internal displacements ('flows') reported since the beginning of 2025. Finalized and validated estimates are published separately in the annual Global Internal Displacement Database (GIDD).

Use Cases

• Monitor daily displacement trends based on provisional conflict and disaster event data.
• Analyze displacement flow patterns based on the distinction between 'flows' (new movements) and 'stock' (total displaced).
• Cross-reference preliminary IDU estimates with finalized GIDD data based on the described data validation pipeline.

Strengths

• Updated daily, providing near-real-time provisional data.
• Sourced from the authoritative Internal Displacement Monitoring Centre (IDMC).
• Focuses on 'flows' (new displacements), a key metric for event analysis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provisional and may require preprocessing to avoid double-counting as noted in the description.
