Migration - National Insurance Numbers (NINos) issued to non-UK nationals

The issuing of National Insurance numbers (NINo) gives us some insight into economic migration, as all non-UK nationals require a National Insurance number to work in the UK. However, the issuing of a number is no long-term indicator of that person remaining resident in the district where it was applied for, and there is no requirement to relinquish the number on leaving the country. For this reason the NINo does not reflect emigration (migrants who leave the UK) or the overall migrant population.
