What we need is weighting in a given area - David, say, who obviously
knows 'his' local area gives weightings according to how important he
thinks a location is - say Cambridge gets 10 as the regional centre,
then tiny hamlets get 1, and so on. Then <handwaving> the renderers deal
with the relative label sizes </handwaving>

Absolutely. People who live in a place tend to know what kind of place
they think it should be. Everyone in Hay-on-Wye (and indeed lots of
similar places in the Welsh borders like Kington, Prestatyn, Llandindrod
Wells) would call it a town, no one in Linton (3 times larger) or
Sawston (4 times larger) would think of it as other than a village.

Perhaps - certainly I think of Bedford (town) and Cambridge (city) as
being on a par in how they should appear, and different from nearby St
Neots (pop 29,000, definitely a town, but not in the same league as
But the place where I feel the need to distinguish most is in the mid
thousands - 2,500 - 10,000 people. I wouldn't want to classify St Neots
in with Linton, 7 times smaller. In the hundreds of people, we're almost
always talking about a village, but I'd be reluctant to lump those in
with hamlet where we're talking well under a hundred.
So maybe I want both
small_town or large_village
large_town or important_town
Or maybe I'm wanting a
or some such.
population=N isn't enough (c/f Hay on Wye), though maybe it could be if
used in conjunction with the existing place tags, so
place=town, population > 50,000 is rendered more prominently than
other towns; and
place=village, population > 2,500 is rendered more prominently than
