Question to the Department for Levelling Up, Housing & Communities:

To ask Her Majesty's Government, in relation to establishing housing allocation numbers for local authorities, what is the current assumed net immigration for each of the next 15 years.

The Government does not set housing allocation numbers. The Government’s Local Housing Need formula, otherwise known as “the standard method” is set out in guidance and is used by local authorities to determine the starting point when planning for housing. Local planning authorities should take into account land supply considerations and environmental constraints (such as Green Belt) before determining the number of homes likely to be delivered in the area.

The standard method is based on the 2014 household projections, these projections incorporate population projections and therefore migration data. Population data is published by the ONS, see attached: https://www.ons.gov.uk/peoplepopulationandcommunity/populationandmigration/populationprojections/bulletins/nationalpopulationprojections/2015-10-29.
