How Warconomy uses this source

IOM's General Population Survey (GPS) rounds produce a survey-based estimate of internally displaced people in Ukraine, not a registration count. Round 22 (fieldwork through Dec 2025) and Round 23 (Jan-Mar 2026) estimated a range of roughly 3.7-3.9 million IDPs; the two rounds are not directly comparable snapshots of the same day, and IOM's own methodology note treats this as a survey estimate, not a census. Not fetched at runtime.

• irregular/policy cadence; re-verify against the source

Citation readiness is a derived label from the source’s authority, role, and how directly it backs a maintained value — not a correctness claim.
