According to https://www.niche.com/k12/search/largest-school-districts/m/..., Fairfax County (Virginia) has 187 thousand students, Montgomery County has 159 thousand, and the District of Columbia has 48 thousand.

My impression is that the size of suburban districts varies greatly by state. Of those I am acquainted with, in Colorado, Maryland, and Virginia every county or county-equivalent city has one school district. In Pennsylvania there can be several school districts in a county, some small enough to have one high school. I think that New Jersey is very fragmented also.

On the west coast it seems like school districts often only cover a single city. Here are the lists for Washington, Oregon, and California. There are tons.

Interesting. Of course, there are some really sprawling counties out west, e.g. San Bernardino County.
