Hawaii kind of handles things in the other direction... my sister and her family lived there from the late 1990s to about 2011 or 2012, before they moved back to California (though not back to southern California). I did some rudimentary studying on how things work in Hawaii because while my sister was living there, she told me that they don't have individual school districts like in California; all the schools are administered by the state. When she told me that, I was like "Whaaaat??"
Being the small state that it is, Hawaii only has 4 counties---5 counties, if you include the consolidated City and County of Honolulu. There are no incorporated municipalities in Hawaii; all communities are governed at the county level.
The City and County of Honolulu is basically all of the island of Oahu and some smaller outlying islands. The total population is 1,016,508, and that's for the whole city/county. BUT, for statistical purposes, the US Census Bureau treats Honolulu differently from the rest of US cities; they consider Honolulu's "city population" to be that of the "urban portion" of Honolulu, which would be 343,302. My sister used to live in "Honolulu," but some years later, they moved to "Pearl City, HI," which technically, is still part of the City/County of Honolulu, but was treated like a separate community, census-wise (population as of 2020 being 45,295).
What was the point of my saying all this? Sorry, I'm at work right now, so a bit distracted. I guess my point is that... I don't know.
I think I was trying to compare the rest of the US, how Hawaii treats its population/municipalities differently. (?)
