Tanzania Internal Displacement Data: New Displacements and IDP Stock

The Global Internal Displacement Database (GIDD) provides validated annual estimates of internal displacement worldwide, maintained by the Internal Displacement Monitoring Centre (IDMC). It tracks two primary metrics: the total number of people living in displacement at year-end (IDP stock) and the number of new displacement incidents recorded (new displacements). This dataset focuses specifically on the United Republic of Tanzania, with data last updated in March 2026.

Use Cases

• Modeling displacement drivers based on conflict and natural disaster triggers mentioned in the description.
• Analyzing long-term trends in internal displacement stock figures for Tanzania.
• Estimating humanitarian needs based on new displacement incidents, which count events rather than unique individuals.
• Comparing displacement patterns across different causes as defined by the 1998 Guiding Principles.

Strengths

• Data is validated and maintained by the authoritative Internal Displacement Monitoring Centre (IDMC).
• Distinguishes between population stock and new displacement flows, a key methodological feature.
• License is CC-BY-3.0-IGO, permitting open use with attribution.

Limitations

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