Reassessment of the statistics
On 26 January 2017, the Office for Statistics Regulation published a report on the reassessment of the National Insurance number statistics.
We welcome the report and in particular that it upholds the quality and accuracy of the National Insurance number statistics. These statistics now carry an ‘Official Statistics’ badge – as the Office for Statistics Regulation have suspended the ‘National Statistics’ badge and set out some requirements for the statistics in order to have the National Statistics badge reinstated.
We have addressed a number of these requirements. The Office for Statistics Regulation will further review the status of the statistics.
On 7 March 2016, the Office for National Statistics (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 National Insurance number registrations.
On 12 May 2016, ONS published an 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.
