Breakdowns
What this measures
The number of National Referral Mechanism referrals for modern slavery raised for people who arrived by small boat, counted in the quarter the person arrived.
What this doesn’t measure
Referrals for people who arrived by other routes, or the final judgment on whether the person was a victim — many referrals await a decision.
Important caveat
Detected small boat arrivals summed from the Home Office detailed dataset; official statistics in development, not accredited official statistics. Nationality, sex and age group are as recorded at detection, and a share of recent arrivals is "Not currently recorded". Undetected arrivals are not included. Data for 2026 Q1 onwards is provisional and will be revised.
Revision history
No period of this series has been revised since it was first ingested here. Revisions are recorded automatically when a later release publishes a different figure for the same period.
