Yes, it is correct there should likely be residential areas nearby, maybe a few km for some of them.  My point was that simply doing an "inside" query is not enough.  I don't know that overpass is capable of returning schools that are *not* nearby residential areas, only inside.  You can return schools that *are* nearby residential areas, or residential areas near schools, but as far as I know there is no way to query on the opposite.

But it does identify locations where there should be say 100 people living
within walking distance.

I'm using search in JOSM currently and there are a fair number of villages
I've picked up by zooming into locations that have a school but the rest of
the map is totally blank.

If I'm feeling nice I try to add in a connecting highway as well.

This won't actually give you useful data.  A signifigant number of the
schools in Mali and elsewhere in Africa are not actually located in the
town they serve, but rather about 1/2 km or so outside of the town, or
about halfway between two or more towns. So a significant number
actually shouldn't be in a residential area.

One of the nice things about schools is they have pupils which implies
people living nearby.

In Mali there appears to be an import of schools based on UNICEF data.
amenity=school source=UNICEF

Could some nice person put together an overpass of any schools that are
not
within a landuse=residential or place=village or town please?

I can do a fair bit in JOSM but I suspect an overpass set of results
which
could be imported into JOSM would help pick out the larger unmapped
villages.

I suspect similar data might be available for other countries.

Thanks John
