[Talk-GB] UK cities

I was watching the quiz show Holding out for a Hero last night on TV and one of the questions was how many cities are in the UK. The correct answer out of 26, 46 and 66 was 66. Sorry for the spoiler if anyone had recorded it to watch later and couldn't have guessed. However I idly wondered at the

Since city status is such an emotive subject in the UK and I believe there's some kind of competition to choose another couple of cities to be created this year, I think we should stick with the officially designate dlist Regards Brian On 17 October 2011 10:48, Ed Loach e...@loach.me.uk wrote:

Why are we missing St David's? Although it has a cathedral, it's not a city. It's widely regarded as one, but it's not on the official list. Simon On 17 October 2011 10:48, Ed Loach e...@loach.me.uk wrote: I was watching the quiz show Holding out for a Hero last night on TV and one of the

I don't think the tagging of place=city has ever reflected official city status. You could change it, but that would be a departure from existing practice. I doubt most people would expect to see 'London' and 'Westminster' as equally-sized cities within a few miles of each other. The existing

Another way of looking at this is that it comes from tagging a 'place node' rather than mapping cities as areas. Individual nodes for counties have been phased out in favour of exact boundaries and the same could happen for towns and cities. If you map an area, that forces the choice of whether
