IDU: Internal Displacement Updates for Conflict and Disaster Events

The Internal Displacement Updates (IDU) dataset from the Internal Displacement Monitoring Centre (IDMC) provides provisional event data on new internal displacements. It focuses on displacement flows reported within the last 180 days and is updated daily. The dataset offers initial assessments sourced from various publishers before final validation in the annual Global Internal Displacement Database.

Use Cases

• Monitor daily displacement flows based on the 180-day reporting window mentioned in the description
• Analyze provisional trends in conflict-induced displacement based on the event data nature
• Compare initial displacement estimates with finalized annual data from the GIDD database
• Track disaster-related population movements based on the dataset's stated scope

Strengths

• Updated daily, providing timely provisional data
• Covers a rolling 180-day time period for recent events
• Sourced from the authoritative Internal Displacement Monitoring Centre (IDMC)
• Released under a CC-BY-3.0-IGO license for open use

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
