As others have said, we strive for global applicability.  I shudder every
time I see "But in
my country, we use this tag differently,"  Carto used by different
countries may differ in how
features are displayed, but (ideally) the meaning of the tag should be the
same.  In the
case where a country has something that doesn't quite fit current tagging
(such as Dutch
polders or Spanish dehesas) we should come up with new tags rather than
force square
pegs into round holes: data consumers don't read the wiki to figure out how
a tag
is used in a particular country.

There are also problems in the UK with what these terms meant historically
versus
how they're used today versus how the wiki defines them.  Historically, a
town had at
a market and least one place of worship; a village had at least one place
of worship
but no market; a hamlet had no market and no places of worship; a city had
a royal
charter which was usually granted to anywhere that had a cathedral (there
were and
still are exceptions both ways).

These historical distinctions are still followed, to an extent: the village
of Cilgerran became
a town when the economy expanded enough for it to have a market and was
relegated to
being a village when the economy collapsed and there was no longer a
market.  Towns
without cathedrals are more likely to be formally granted city status than
in the past.  Some
large towns have taken to calling themselves cities even though they do not
have a royal
charter awarding them that status.  Many villages have lost all their
places of worship
but are still referred to as villages rather than hamlets.

OSM uses these terms based on population.

What any given place in the UK is mapped as depends on the local knowledge
of the
mapper and how strictly the mapper follows the wiki.  It's a bit of a mess.
