For an african city example you could use Zliten, Libya.

https://www.openstreetmap.org/#map=12/32.46/14.5587

I marked the surface=* values there from satellite imagery there a
couple years back as part of the HOT activation during the civil war
there.  The core of the city is paved and the outer portion is all
unpaved, with the main roads going in and out of the city being paved
as well.  Everything in the city and the surrounding area should have
a surface tag on it, as I systematically checked them using the
'Surface data entry' paint style in JOSM.

We have also been doing a lot of tracing in West Africa (specifically
Liberia and Sierra Leone with a bit in Guinea).  These roads are not
all tagged with surface values though other than a few isolated
pockets.  We had been wanting to do better surface data though so if
you message the HOT mailing list with a request for a specific area in
one of these countries we could try to add the surface tags for you.
Just browse around and see where you think it would make sense and let
us know.  Can't guarantee we will get it done for you, but like I said
we did want to get more surfaces tagged anyway and this way we could
kill two birds with one stone.
