§ Mr. Willetts
To ask the Chancellor of the Exchequer how many items of data were inputed on to national insurance records held on the N1RS2 computer system in(a) 1997–98, (b) 1998–99 and (c) 1999–2000 to date. 
§ Dawn Primarolo
Small amounts of data were inputed to National Insurance records held on NIRS2 from 28 January to 18 June 1998. From 13 July 1998, input of data increased incrementally as additional parts of the NIRS2 system were implemented.
I regret that the full and complete information requested for 1998–99 and 1999–2000 is not available.
The largest single source of data for inputting to records held on NIRS2 is the annual National Insurance update received from employers. The vast majority of this data is inputed to records during the tax year following the year it is collected. Inputting to NIRS2 started at the end of August 1998 and the following volumes of data have been inputted so far: for the 1997–98 tax year, 45.1 million items; for the 1998–99 tax year, 46.4 million items.
The main daily inputs to records held on NIRS2 in terms of volume have been estimated from samples taken in November 1999 and December 1999. The average is:
Per day External inputs 214,000 Transactions processed 1,964,000 On-line Inputs 251,300 Update of contribution information from employers 199,000
