The ONS published a welcome note yesterday updating the progress being made with statistics on the migration patterns of international students coming to the UK. It gave a fairly upbeat impression but really only laid bare how little we as a nation know about these students. New statistics are needed – and requiring all students to get a National Insurance Number would be a good start and might even be part of the post-Brexit changes. Lets hope that the ONS and UKSA Board are in there arguing for such changes. The article also had a graphic that was misleading and below the standards that we might expect from the ONS.

The ONS and its governing board, UKSA, does not lie but on migration their statements stretch credibility and do nothing to boost public trust in data. The ONS needs to change its stock press briefing that the passenger survey is “the best available source” for migration data. It is true but only because it does not seek a better source. It’s like telling a cancer patient that an x-ray is best when we know the (more expensive) scan is better – it might help at the margin in some cases but it’s not what’s needed. It is damaging to give such a deeply misleading impression of the data’s veracity. For the same reason, the ONS needs to stop publishing confidence intervals on migration data.
The UKSA needs to say it as it is – migration numbers are not fit for purpose and a new system (and more money) is needed to collect decent numbers. Brexit will require better data so UKSA would no longer be saying anything radical. Pretending that the figures are OK is not only a failure of its regulatory duty but provides cover for a Home Office that really needs to get on with what’s required – the not so tricky job of counting people crossing borders.
