UK net migration has fallen sharply from its early-2023 peak: the Migration Observatory (University of Oxford), drawing on ONS data, reports that net migration fell to about 171,000 in the year ending December 2025, a decline of roughly 82% from the peak of around 944,000 in the year ending March 2023. The ONS likewise reports a continuous fall since the March 2023 peak (from 649,000 in the year ending June 2024 to 204,000 in the year ending June 2025). Measured from that peak, the 82% figure — also cited publicly by the Home Secretary — is accurate. (Note: measured only against the immediately preceding year, ending December 2023, the fall is about 50%; the 82% refers to the fall from the 2023 peak.)","sources":[{"url":"https://migrationobservatory.ox.ac.uk/press/falls-in-net-migration-small-boat-arrivals-and-asylum-claims-as-just-under-one-in-five-in-the-uk-are-foreign-born/","ente":"The Migration Observatory, University of Oxford","titolo":"Falls in net migration, small boat arrivals and asylum claims","estratto":"Net migration fell to 171,000 in 2025, a decline of 82% since the early 2023 peak."},{"url":"https://blog.ons.gov.uk/2025/11/27/what-is-driving-the-current-fall-in-net-migration/","ente":"Office for National Statistics (ONS)","titolo":"What is driving the current fall in net migration?","estratto":"Net migration has been falling since its peak in the year ending March 2023; it provisionally fell from 649,000 (YE June 2024) to 204,000 (YE June 2025)."}],"issued_at":"2026-07-01T07:58:27+00:00"},"signature_b64":"ZqkKtQ8syGYECLOgtfnePGyoIFG76cnl3rbs5flX6r0XkRpaQiB8cK6XGLmrmCsO6i4VRoRh8rFBNKnOV6q1BA==","public_key_hex":"1719e2638a2cc0ec8d552d71dca52197f934e0a66b17e6364f1eed7a1d428e01","note":"Verifica offline: ed25519_verify(public_key, base64decode(signature_b64), canonical_json(payload))."}
