National Insurance Number (NINo) registrations to adult overseas nationals entering the UK by year of registration, by country of origin.

100% extract from National Insurance Recording System.

Figures are rounded to the nearest ten. Some additional disclosure control has been applied. Totals may not sum due to rounding method used.

Registration date is derived from the date at which a NINo is maintained on the National Insurance Recording System.

Time Series - Year Of Registration Date Years are shown as financial year (1st April - 31st March).

Overseas Residents - Foreign nationals who have registered for a NINO but reside abroad.

Geographical location is assigned by matching postcodes against the relevant postcode directory. Geographical counts are based on individuals recorded address at the time of scan for that reporting period - the individual may have subsequently moved out of the area or back abroad.

Note: A small number of registrations have an unknown geography and are not represented in these tables. However the total figures, including those with unknown location, are quoted in DWP publictions so numbers may not always agree.
