Especially when there are EOs for naming post offices and other boring mechanical work of the executive.
It would take some serious effort (and there’d be disagreement) but maybe you could classify “important” government changes and if they were enacted by congress, EO, courts, etc.
Also, that link stops with Obama and that leaves out two whole administrations that would be pretty pertinent data in this discussion. Nearly a decade of data. It looks like Trump's first term had 220 and Biden had 162. It would be interesting to see the data classified the way you described and then broken down by party over time. The actual policymaking via EO by each party over the last 50 years would be more elucidating than the straight numbers for sure.
