IDU: Internal Displacement Event Data for Conflict and Disaster

The Internal Displacement Updates (IDU) dataset from the Internal Displacement Monitoring Centre (IDMC) provides provisional event data on new internal displacements caused by conflict and disasters. It offers daily updates on displacement flows over a rolling 180-day period. The finalized and validated data is published in the annual Global Internal Displacement Database (GIDD).

Use Cases

• Monitoring near-real-time displacement flows based on the 180-day rolling event data.
• Analyzing triggers of internal displacement based on the conflict and disaster event categorization.
• Comparing provisional IDU estimates with validated GIDD stock data for trend validation.

Strengths

• Updated daily, providing timely provisional information.
• Covers a rolling 180-day period for recent displacement events.
• Sourced from the authoritative Internal Displacement Monitoring Centre (IDMC).

Limitations

• Data for Antarctica shows no recorded displacement flows in the last 180 days, indicating potential geographic gaps.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
