There are statistics raw, and there are statistics adjusted. By and large, the more statistics are adjusted to give a 'clearer view', the more careful you've got to be about them.
With that in mind, I want to share some observations on Friday's US labour survey data. On the face of it they were extremely positive: non-farm payrolls were up 467k, and Dec's payrolls were revised up to 510k from an initial 199k. Even more spectacularly, Jan's h'hold survey of employment found employment up 1.199mn, which was the sharpest monthly gain since January 2000, on the back of an extraordinary 1.393mn rise in the labour force as the labour participation rate rose 0.3pps to 62.2%, the highest since March 2020.
Not only are these really dramatic gains, but they also run absolutely counter to what ADP found in its Jan survey of private employment, where payrolls fell by 310k.
What's going on? The thing you need to is that the strength of Jan's labour survey results is largely the result of statistical adjustment of truly monstrous proportions. The seasonally adjusted establishment survey of non-farm payrolls rose 467k mom, but the unadjusted number show a fall - yes, a fall - of 2.824mn mom. Similarly, the household survey's reported a seasonally adjusted 1.199mn rise in employment: but strip out the seasonal adjustments, and the raw numbers show a fall of 114k in January.
There are at least two different things going on here, quite apart from the 'normal' seasonal adjustment. The first is simply that the Bureau of Labor Stats has revised its seasonal adjustment process, notably taking into account the massive disruptions seen during the onset of the pandemic and subsequent recovery. This is responsible for the major upward revision in Dec's data, with the massive strength in June/July last year being quietly, and for these purposes invisibly, being revised down. This is what is behind the abnormal and anomalous seasonally adjusted strength in non-farm payrolls reported in January.
The impact of this change is going to be felt throughout the year: essentially it will bias non-farm payrolls results upwards through to May, before reversing the bias downwards sharply from June through to November. You've been warned.
The second concerns a big technical change in the h'hold survey - the once which produced a rise of 1.199mn in January's employment despite a non-adjusted fall of 114k. What's happening here is that Jan's survey introduced updated population estimates, with a new estimate of population from the 2020 census & later data, rather than the 2010-based data which was what was used for the Dec 2021 survey. That, and that alone, raised the estimate of the labour force in Jan by 1.53mn, raised employment by 1.47mn, and unemployment by 59k.
And you'll have spotted it: if the change in census base raised employment by 1.47mn, and Jan's survey reported a rise of only 1.199mn, what it is telling is is that on same-survey basis regardless of seasonal adjustment issues, h'hold employment actually fell by 272k.
To summarise: we're all going to have to take the monthly labour market surveys from the US with a very large pinch of salt for the coming year: the next few months are going to be great: after that, not so much.
