answer text: [holding answer 10 November 2008]: The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.Letter from Karen Dunnell, dated November 2008:"As National Statistician I have been asked to reply to your question asking what the most recent forecast is of the proportion of population growth (a) directly attributable and (b) indirectly attributable to migration in each of its projections of population size (234137).""The most recent national population projections, based on mid-2006 population estimates, were published by the Office for National Statistics on 23 October 2007. The principal projection was produced using the main assumptions of future levels of fertility, mortality and migration. However, to give users of the projections an indication of the effect of higher or lower assumptions, a number of variant population projections were also produced.""An understanding of the overall effect of migration on population growth can be obtained by comparing the results of the principal and high and low migration variant projections with those of the 'natural change' (or zero migration) variant projection. Table A below gives projected components of population change for the UK in the period to 2031 in the principal projection, the high and low migration variants and the natural change variant projection.""Table B shows how the projected population growth to 2031 is broken down between the assumed level of net migration and projected natural change. Natural change is then further broken down into that projected in the absence of migration and the additional natural change from the assumed level of net migration. So, taking the principal projection for example, some 47 per cent of population growth is therefore directly attributable to the assumed number of net migrants. The remaining 53 per cent is attributable to projected natural increase (of which 31 per cent would occur in the absence of net migratio…
