Answer

Mr. Willetts: To ask the Secretary of State for Social Security how many national insurance numbers there were on (a) the Departmental Central Index and (b) NIRS1/NIRS2, in each year since 1992. [152436] Mr. Rooker: The figures are set out in the tables. The difference between the number of records held on DCI and NIRS1/NIRS2 is because: DCI holds records for 12.5 million children [Child Reference Numbers]. Such records are notified to NIRS2 only as and when the children approach age 16. DCI holds NINOs allocated to customers who are over Retirement Pension age. These records are not notified to NIRS2 as there is no contribution liability. The DCI Data Cleansing work is incorporated within the current core business. This includes such activities as data cleansing, data maintenance and the removal of duplicate and surplus NINOs. The rise in number of NINOs reflects the fact that while additions are made each year for children who reach 16 and others who apply for a NINO. Records need to be retained in the event of a surviving spouse making a claim on their partner's contribution. National Insurance numbers held on DCI _________________________________________________________________________________________________.
