IDU: Daily Internal Displacement Flows in Iran from Conflict and Disaster

IDMC's Internal Displacement Updates (IDU) dataset provides provisional daily data on new internal displacements (flows) in Iran caused by conflict and disaster. The data is sourced from initial assessments and updated daily, representing the most recent available information. Finalized and validated estimates are later published in the annual Global Internal Displacement Database (GIDD).

Use Cases

• Monitor daily displacement trends based on provisional conflict and disaster event data.
• Analyze displacement flows for early warning and humanitarian response planning based on daily updates.
• Cross-reference provisional IDU data with validated annual GIDD stock figures to understand data evolution.

Strengths

• Updated daily, providing timely provisional data.
• Sourced from the authoritative Internal Displacement Monitoring Centre (IDMC).
• Covers both conflict and disaster-induced displacement events.

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 be subject to revision and double-counting.
