So, taking the office of national (UK) statistics - in 2013 the growth rate of the population is 0.6%, on 64 million. Giving you 384,000 extra per year - about half of the growth is (births - deaths) and the other half is net migration [1].
Meanwhile from 1990 onwards we're seeing an average of less than 200,000 [2] - In the last few years the rates are the lowest for the time period on the graph (back to the 1970s).
