IDU: Daily Updates on New Internal Displacements from Conflict and Disaster

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

Use Cases

• Monitor daily displacement trends based on the 180-day rolling event data mentioned in the description
• Analyze provisional displacement flows from conflict and disasters based on the event-based structure
• Compare preliminary IDU estimates with finalized GIDD data for validation studies

Strengths

• Updated daily, providing near-real-time provisional information
• Focuses on displacement flows over a defined 180-day period
• Data is provided by the authoritative Internal Displacement Monitoring Centre (IDMC)

Limitations

• Data for Democratic People's Republic of Korea shows no recorded displacement flows in the last 180 days
• Provisional nature of data requires careful preprocessing to avoid double-counting
• Column-level documentation is absent; field semantics must be inferred after download
