Official figures show net migration to the UK drops below 200,000 in 2025, falling to about 171,000, the lowest level since 2021, according to reports citing data released by the Office for National Statistics (ONS). The figures measure the difference between the number of people arriving in the UK and the number leaving. Multiple outlets describe the decline as close to a 50% reduction year-on-year. The ONS data indicate the gap between inward and outward migration is at its weakest point since the early post-pandemic period. The lower net migration figure is presented by political coverage as a potential boost for Prime Minister Keir Starmer and the Labour government, particularly on an issue that has been central to debate with Reform UK. One report frames the change as coming in the context of Labour’s vow to cut migration numbers, while all accounts focus on the same headline outcomes: net migration falls to roughly 171,000, dips under 200,000, and reaches the lowest level since 2021.
