Migration

Answer

The information requested falls within the responsibility of the National Statistician, who has been asked to reply.Letter from Karen Dunnell, dated 14 January 2008:"As National Statistician I have been asked to reply to your question regarding how many estimates of long-term population growth attributable to migration have been made by the Government since 1997; what those estimates have been, including the most recent longest term estimate of population growth attributable to migration and total future population size; what assessment he has made of the environmental and housing implications of these estimates; and what the Government's population policy is. (177459)""National population projections, based on a full review of all the underlying assumptions, are normally produced every two years. The most recent set is the 2006-based national projections published in October 2007. In the intervening year between these 'full' projections, special sets of 'interim' national projections may be produced. Two sets of interim projections (2001-based and 2003-based) have been produced in recent years.""The underlying assumptions for the projections are demographic trend based and should not be seen as predictions. If, as in recent years, there is an increase in migration levels then the assumptions are changed to reflect this. The long-term assumptions of annual net migration to the United Kingdom in these recent national population projections have been as follows:"

Based projections
1998	+95,000
2000	+135,000
2001	+100,000
2002	+130,000
2003	+130,000
2004	+145,000
2006	+190,000

"Since the 2002-based projections, an analysis has been published of the impact of the assumed level of net migration on population growth in the period to 2031. These analyses are available from the following links:""2002-based projections""http://www.gad.gov.uk/Demography_Data/Population/2002/methodology/mignote.asp""Interim 2003-based projections""http://www.gad.gov.uk/Demography_Data/Population/2003/methodology/mignote.asp""2004-based projections""http://www.gad.gov.uk/Demography_Data/Population/2004/methodology/mignote.asp""2006-based projections""http://www.gad.gov.uk/Demography_Data/Population/2006/methodology/mignote.asp""The Office for National Statistics cannot comment on the policy issues raised in your question."
