These numbers include upward revisions for past months.

You make a good point about these types of numbers. It's hard to get accurate and timely data in the field of economics, and headlines will never show the revisions, so the information we see will usually be the least accurate (assuming accuracy grows with time).

That said, these are good numbers and there's no reason to suspect they're not real.

Estimates for November and December were also revised up, by a combined 126,000 jobs.

I feel like I've never heard so much about multi-sigma job beats than I did last year. At what point do we say that something weird is going on?

For those who're wondering what the sigma beat was this time, it was a 4-sigma beat, which is pretty large.
