Yes it does:'The growth in the population of the UK is mainly due to net natural change (more births than deaths). Natural change accounted for over 80 per cent of the total population change between 1981 and 2001. The rest of the population change is due to other changes. Although the main component of these other changes is net civilian migration, this is not the only component. '
