Mr. Lilley: To ask the Chancellor of the Exchequer what (a) medium and (b) long-term assumptions about net immigration into the UK have been made in each of the population projections produced by the Office for National Statistics since 1990; and what has been the outcome in each year over that period.

John Healey: National population projections are produced by the Government Actuary‘s Department at the request of the Registrars General of England and Wales, Scotland and Northern Ireland. New projections are normally prepared every second year. The 2000-based, and earlier, projections were prepared before 2001 Census results became available. The interim 2001-based projections take preliminary account of the results of the 2001 Census. A 2002-based set of projections, taking account of the further Census related data which has and will become available during 2003, is provisionally scheduled for publication in the autumn.
