The charts paint a much more precise picture on what is happening, and I actually don't see anything that strongly support it being a partisan effect.
Can you explain why? Given that it's presumably averaged over the president's entire term, doesn't that provide a good measure of how much jobs were added under a given administration?
Also think of average populations under constant growth, as under Obama and Trump I pre-COVID: Trump's average would be higher in absolute terms than Obama, despite no fundamental change, and Biden higher still, and Trump II higher yet. Absolute populations and jobs go hand in hand. Averages without normalization are statistical theater.
Us Wikipedians have done a poor job on the federal statistical system (FSS or NSS), and this one of many results, this HN thread. I am working on it with the help of chat bots, but progress is slow given my focus on US healthcare and welfare systems. Fundamental laws have been documented, but the actual systems they enable are poorly documented.
