Dataset: National Insurance Number Registrations to Adult Overseas Nationals Entering the UK

Description

The data covers adult overseas nationals entering the UK and allocated a National Insurance Number (NINo). A NINo is generally required by any overseas national looking to work or claim benefits / tax credits in the UK, including the self employed or students working part time.

Figures are based on recorded registration date on the HMRC National Insurance Recording and Pay as you Earn System, i.e. after the NINo application process has been completed. This may be a number of weeks or months (or in some cases years) after arriving in the UK

All Adult overseas nationals allocated a NINo are included regardless of their length of stay in the UK.

What you need to know

This data contains 100% statistics on National Insurance Numbers (NINo) allocated to adult overseas nationals, covering the period from January 2002 to September 2016.

The NINo statistics show the number of people registering for a NINo in order to work or to claim benefits / tax credits and are one of a number of supplementary measures produced by Government of in-migration to the UK

They are a measure of in-flow to the UK, primarily for employment, including both short-term and long-term migrants and include foreign nationals who have already been in the country but not previously required a NINo as well as migrants who may have subsequently returned abroad.

The statistics are published as part of the scheduled timetable for the release of cross-Government migration statistics. The Migration Statistics Quarterly Report (MSQR) is a summary of the quarterly releases of official international migration statistics by the Office for National Statistics (ONS).

NINo statistics are not a direct measure of long term migration and therefore are not directly comparable with ONS long-term estimates of immigration. On 7 March 2016, the ONS published an information note explaining the reasons why long-term international immigration figures from the International Passenger Survey (IPS) could differ from the number of NINo registrations.

On 12 May 2016, ONS published a follow up analytical paper presenting analysis that has been undertaken across government to help understand why the 2 series are showing different trends, with focus on EU migration.

Known Issues

Statistical disclosure control has been applied with Stat-Xplore, which guards against the identification of an individual claimant, for this reason, no reliance should be placed on very small numbers obtained through Stat-Xplore.

Q2 2009 - Quarterly count may reflect operational downtime in the recording system during the quarter.

A change to the process of recording NINOs during the quarter April-June 2014, means that the volume of NINo registrations recorded were lower in that quarter and then higher in the subsequent quarter July to September 2014 than would otherwise be the case. Therefore, comparisons of NINo registrations over these quarterly periods should be viewed with caution.

Allocation Process and Data Collection Methods

In order to apply for a NINo, in the first instance, a migrant worker makes an inquiry to a Job Centre. They must attend an "Evidence of Identity interview" at a local DWP Jobcentre Plus office where they must be able to prove that they are who they say they are and that they satisfy the criteria for needing a NINo.

The Jobcentre Plus interviewing officer will usually complete security form CA5400 Application for a NINo on behalf of the applicant who will then sign the form (applicants may complete the form themselves if they wish). The form is countersigned within DWP and passed to a Jobcentre Plus National Insurance Number Centre together with copies of supporting identity documents for allocation of a NINo on the DWP Customer Information System (CIS). The papers are then referred to HMRC NICO NI Registration section to create a full NI account on NPS.

DWP receive a quarterly cumulative scan from the NPS which contains details of all adult overseas nationals allocated a NINo up to the date the scan was run. This is used to produce these National Statistics.

The figures encompass adult overseas nationals allocated a NINo for whatever reason, i.e. the figures cover benefit/tax credit recipients as well as workers (including self employed). All adult overseas nationals allocated a NINo are included, regardless of their length of stay in the UK.

They are based on recorded registration date on NPS, i.e. after the NINo application and allocation process has been completed. This may be a number of weeks or months after arriving in the UK. The registration series is not subject to any future change.

Field: Westminster Parliamentary Constituencies (Excluding Northern Ireland geographies)

Description: The location of the client at the time of their registration.

Westminster Parliamentary Constituencies are assigned by matching the client's postcode at registration against the ONS postcode directory. Where postcode is not known, address matching software is used to determine client's geographies. As the client's postcode is updated retrospectively, geographies are tabulated using the initial address of the client at the time of registration.

Westminster Parliamentary Constituency boundaries build up exactly into regions and then regions build up exactly into countries.

Westminster Parliamentary Constituencies are not available for Northern Ireland with this data so this geographical breakdown does not include any Northern Ireland geographies apart from Northern Ireland itself.
