Hi,
I thought I would try giving something back to the community in the spirit of the holidays, and I am kind of between projects right now, so I had some spare time to wrap this up nicely.
For a project earlier this year I assembled and georeferenced a UN Population Division database, of large urban areas (with more than 750000 inhabitants) with historic observations and estimates going back to 1950, and projections up to 2050. Pretty cool, I would say.

Anyways - I have created a page with more information, and download links. Be sure to check out the video clip/animation that I prepared and the Google Earth presentation.

Nice stuff. I like the historical aspect to it. How does this compare to what is on the Natural Earth Vector site?

Rudy - I don't think there is that much point in comparing them. I see Natural Earth Vector as basemap data, and this dataset is more of thematic data. You can do interesting things with this data, in looking at trends and distribution, but I think Natural Earth might be better for base maps.
I guess one should join them up though, to make it even more interesting...

/me heads off to the Natural Earth forum to offer this dataset
