A lot of these enrollment metrics have been driven by early childhood education, so I wouldn't put that much stock in this being some sort of wider trend in terms of desire to enroll a child in school. But there absolutely is a trend in terms of the LACK of desire to be in a school as an adult; it has gotten harder and harder to recruit, and, speaking quite candidly, the job of being a teachers has actually just gotten worse. Naturally, this correlates with a reduction in the quality of the folks that we get to be in our classrooms (even at institutions like mine that pay top dollar for teaching talent).
Even from where I am sitting it is extremely hard to confidently extrapolate what the long-run equilibrium of this will be. There's a camp that believes that this could have been a watershed moment for online instruction, but if you followed the play-by-play on the ground, it was almost the complete opposite: folks have been so disappointed by what counted as online instruction that in-person, good-ol-fashioned teaching has never been so highly sought. My guess is we will normalize with COVID protocols, staffing, and the rest fairly soon, and we'll returns to previous trends. The worst kept secret in primary education is that even at the high-school level for the most part we're little beyond a glorified day-care, and that the folks' who ought to matter most (the students) are pretty voiceless. This all combines for a fantastic recipe for why there is so much stasis in education, and unfortunately I think the smart money is on betting this won't change much at all, even after COVID.
