I expect the second most common reason is some financial disaster

which "losing your job and having to get a new one, some miles
away" falls into

It's the *having* to move which is the disaster. Sometimes it's
possible* to get a job locally, or rely on a joint breadwinner, or
have a longer* daily commute, or even a weekly commute.

Oh stop moving the goalposts
I'm simply pointing out that that circumstances under discussion are
really quite rare. And have to be pretty dire to uproot the family
from their schools, friends, etc.

You don't know anybody in the services then, or even some civil service
jobs. You get posted from one end of the country to another or abroad,
commuting is out of the question. I moved school several times, three
junior schools and two secondaries, in three different countries.

I do know people who have been through that experience. It's not that
common though. And obviously isn't involuntary, which the scenarios
discussed so far have been.
