The Migration Observatory at the University of Oxford has published a briefing on UK net migration based on ONS data, covering trends since the early 2000s and changes under the post-Brexit immigration system. In 2025, net migration was 171,000—well below levels observed during the 2010s and sharply down from the historic peak of 944,000 in the year ending March 2023. Non-EU immigration fell to 627,000 in 2025, approximately 20% lower than in 2024. Of these non-EU arrivals, 67% came for work or study purposes. Nearly 70% entered the UK to study at universities (44%), work (11%), or join work migrants as partners or children (12%), while asylum seekers accounted for 14%. Indian nationals comprised the largest group, representing 17% of total immigration, followed by Pakistani and Chinese citizens at 7% each. As of June 2024, 19% of the UK’s population was foreign-born—a figure similar to Spain and Germany, lower than in Australia, Canada, and New Zealand, but higher than in France, the United States, and most Eastern European countries.
