Similarly, people who leave the UK are only excluded from the population estimates if they remain outside the UK for 12 months or more. Members of UK and non-UK armed forces stationed in the UK are included in the population and UK forces stationed outside the UK are excluded. Students are taken to be resident at their term-time address.
