it reads "annual percentage change in labor output"... which I take to mean "rate of change of per capita productivity" over time, not actual measured productivity.

So that graph does not say we've dropped below pre-pandemic levels.... according to this report (https://www.bls.gov/news.release/prod2.nr0.htm): "Output and hours worked in the nonfarm business sector are now 3.1 percent and 1.5 percent above their fourth-quarter 2019 levels, respectively."

Not OP, but your reply comes off as pretty rude, especially as I think its pretty off base.

The chart is showing "annual percentage change in labor output", not "gross productivity" which I think supports the OPs point.

If it went up 10% in 2020, and 6.3% in 2021 (or whatever the graph is showing), just because there is a -7.4% drop in 2022 doesn't mean its "far below any pre-pandemic baseline".

In fact it's probably ABOVE pre-pandemic levels, even with the drop. I can't be certain from graph.

The chart only shows change, not the actual value. If you look at a chart of the values you'll see that it's true we've just returned to ~2019 values: https://tradingeconomics.com/united-states/productivity
