A report by the National Institute of Economic and Social Research (NIESR) predicts that zero net migration would shrink the UK economy by 3.6% by 2040. This scenario, driven by falling birthrates and decreased migration, would halt population growth around 70 million by 2030. While GDP per capita might initially rise, the overall economy would weaken due to a smaller, aging workforce and reduced tax revenues. The thinktank forecasts a budget deficit increase of £37 billion by 2040, requiring the government to borrow more. NIESR warns that unless fertility rates increase, zero net migration would necessitate significant tax rises to maintain fiscal sustainability, potentially hindering economic growth.
