That makes sense. I will need read how they have made using the patchy system of existing admin data in this way fit for purpose and whether it is still labeled experimental. The only govt data system I see as gold standard is HMRC real time information on PAYE.

I don't get how the methodology is any better other than it gives a higher figure. It's clear they thought the survey data was implausibly low but it doesn't mean the new method is a accurate reflection of true levels
