IDU: Daily Internal Displacement Flows in Bangladesh

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

Use Cases

• Track displacement triggers based on conflict and disaster events mentioned in the description
• Analyze daily displacement flow patterns based on provisional updates
• Compare preliminary displacement estimates with later validated stock data from the GIDD
• Model humanitarian needs based on population movement trends

Strengths

• Updated daily, providing near-real-time data
• Focuses on displacement flows, a key metric for humanitarian response
• Sourced from the authoritative Internal Displacement Monitoring Centre (IDMC)
• Available via API for programmatic access

Limitations

• Data is provisional and requires careful preprocessing to avoid double-counting
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
