It is tough, though, for me to fully buy labor statistics when it has become the norm recently for them to be revised down. This spans back into Biden's term as well so it isn't one party either.

With a valid measure I would expect a roughly even distribution over time between underestimates and overestimates. For a valid measure worth considering I'd also expect the stat to be released later when revisions are less likely because more actual data has been collected

This is a valid hypothesis. It’s wrong, and I’ll explain why. (It’s a bad and invalid thing to conclude.)

If measurement errors were iid, you’d be correct. But they’re not. They’re well documented for not being so. Earlier survey results are biased by directional response bias inasmuch as the employers with the lease changes respond first. So the earliest releases tend to match whatever was going on before. Then the employers who had to do paperwork respond. And then, finally, someone gets around to calling the folks who never got back. Some of them aren’t around anymore.

So yeah, the directional tendency in revisions is well documented. And for a long time, the early releases were appreciated. But maybe American statistical and media literacy is such that only final releases should be released, which would mean we’d always be working with data 6 months to a year out of date.

That is a reasonable position, however the assumption that it is the administration that is gaming them vs other motivated parties is open for discussion.

There have been revisions since the forever, and this is because they depend in part of surveys, and if companies (and the people with-in them) don't bother responding in a timely or accurate manner then that's going to throw the sampling off.

> CES estimates are considered preliminary when first published each month because not all respondents report their payroll data by the initial release of employment, hours, and earnings. BLS continues to collect payroll data and revises estimates twice before the annual benchmark update (see benchmark revisions section below).

Post-COVID surveying seems to have become more difficult (and BLS budget stagnation/cuts haven't helped). This has been a known issue for a while; see Odd Lots episode "Some of America's Most Important Economic Data Is Decaying":

> Gathering official economic data is a huge process in the best of times. But a bunch of different things have now combined to make that process even harder. People aren't responding to surveys like they used to. Survey responses have also become a lot more divided along political lines. And at the same time, the Trump administration wants to cut back on government spending, and the worry is that fewer official resources will make tracking the US economy even harder for statistical departments that were already stretched. Bill Beach was commissioner of labor statistics and head of the US Bureau of Labor Statistics during Trump's first presidency and also during President Biden's. On this episode, we talk to him about the importance of official data and why the rails for economic data are deteriorating so quickly.
