An early-2000s estimate; later studies found a sharp fall.
Early 2000s · dated UNICEF / IJM CSEC study, 2013A note on honesty: only the Philippines has a recent, rigorous estimate — Scale of Harm (2022). The Thailand, Indonesia, and Cambodia figures are the best that exist, but they are a decade or more old, inconsistent between sources, and in Cambodia's case have since fallen sharply. They are shown, and flagged, because no current per-country estimate of sex trafficking exists anywhere. Even so, the pattern holds: what each government records is a fraction of what researchers estimate is there.
