I would like to know how many people in the UK, turned 17 years of age, last year (2012) and the projected figures through to 2017, based on recorded birth rates.
Table 1 gives the projected numbers to reach age 17 in the United Kingdom for each calendar year from 2012 to 2017. These estimates are derived from the most recent 2010-based national population projections for the United Kingdom published in October 2011. They have been calculated by making assumptions of the number of people aged 16 who will turn 17 in the calendar year. These differ from the published projections data which provide the projected numbers of people aged 17 at mid-year.
The 2010-based national population projections are based on the mid-year population estimates for 2010 and a set of underlying demographic assumptions regarding fertility, mortality and migration. The projections become increasingly uncertain the further they are carried forward. To help understand the uncertainty, a number of variant projections based on alternative assumptions are also produced. National population projections are not forecasts and do not attempt to predict the impact that factors such as future government policies or changing economic circumstances might have on the population.
