Baroness Sherlock
Main Page: Baroness Sherlock (Labour - Life peer)My Lords, I thank the Minister for repeating that Answer. The number of national insurance numbers has never been a good guide to the number of British people resident in the UK, never mind anybody else. The report from the ONS suggests that there have long been differences between, for example, the number of EU8 migrants and the total number of short and long-term migrants, which has consistently been above the number of NINos. Has the Minister’s department had the opportunity to compare the NINo data set out today with, for example, the RTI data that his department holds, self-assessment, or the DWP L2 and tax credit benefit data? That would enable him to make a judgment and perhaps make it quite clear that many of these people are coming in as short-term visitors and not long-term workers.
The noble Baroness is absolutely right. Today’s report focused on whether the International Passenger Survey was the correct measure of long-term migration. There are other data sources, such as those the noble Baroness referred to. Of course, the report stressed that work on independent data sources such as HMRC and DWP data is ongoing, and there will be further such work. However, those are complementary, and it has now been established that the best way of looking at this is the International Passenger Survey.
