Question to the Home Office:

To ask the Secretary of State for the Home Department, what forecast the Government has made of the effect of immigration policy on the ratio of working people to retired people in the next (a) five, (b) 10 and (c) 20 years.

It has been the practice of successive Governments not to make such forecasts. There are numerous different factors that can affect migration flows.

UK Population projections (including variants based on alternative assumptions of future fertility, mortality and net migration) are published by the independent Office for National Statistics at https://www.ons.gov.uk/peoplepopulationandcommunity/populationandmigration/populationprojections
