Hong Kong Internal Displacement Data: New Displacements and IDP Stock

The Global Internal Displacement Database (GIDD) from the Internal Displacement Monitoring Centre (IDMC) provides validated annual estimates of internal displacement. It tracks two primary metrics: the year-end stock of Internally Displaced Persons (IDPs) and the flow of new displacement incidents. The data for Hong Kong is available in CSV format and was last updated on March 18, 2026.

Use Cases

• Modeling displacement trends over time based on annual stock and flow figures.
• Analyzing the correlation between displacement incidents and specific triggers like conflict or natural disasters as mentioned in the description.
• Comparing displacement metrics for Hong Kong against global or regional datasets from the same source.

Strengths

• Data is validated and maintained by the authoritative Internal Displacement Monitoring Centre (IDMC).
• Distinguishes between population stock and flow metrics, a key methodological feature noted in the description.
• Available under the open CC-BY-3.0-IGO license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description does not specify the temporal coverage for Hong Kong data.
