I'm building a visualisation with cities' population around the globe for a website. I found the MaxMind free database that includes most cities around the globe with coordinates and population, which is awesome.
What I'd like to do is have something like a timeline, to show which cities have increased their population in the last years (even from 2005-ish to 2012 would be great).
To do so I would need the same database, but of previous years.
I looked at the Maxmind site, but couldn't find any older versions of their database.
Do you know a place where I can find such a database?
