Mauritius Internal Displacement Data: New Displacements and IDP Stock

IDMC's Global Internal Displacement Database provides validated annual estimates for forced migration within national borders. The dataset tracks two primary metrics: the year-end stock of Internally Displaced Persons (IDPs) and the flow of new displacement incidents, accounting for multiple displacements per person. It is maintained by the Internal Displacement Monitoring Centre and was last updated in March 2026.

Use Cases

• Modeling displacement risk based on conflict and disaster triggers mentioned in the description
• Analyzing long-term trends in internal displacement based on annual stock figures
• Estimating humanitarian resource needs based on new displacement incident counts

Strengths

• Data is validated by the Internal Displacement Monitoring Centre (IDMC).
• Tracks two distinct metrics: stock of IDPs and flow of new displacement incidents.
• Uses a standardized definition aligned with the 1998 Guiding Principles on Internal Displacement.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update timestamp is from March 2026.
