CEA Chair Miran asserts that some of the surprise in the employment numbers is due issues of seasonality. Can we see that? I can’t…

Here’s y/y growth rate of the official series and the seasonally adjusted series.

The seasonally adjusted series is actually above the y/y not seasonally adjusted series!

What about the level?

Another reason to think the BLS numbers have not been “massaged”: the July release numbers better track ADP, on private NFP.

In any case, there are usually big NFP misses around turning points. Civilian employment — which is not revised month to month — peaked in April.
