Interesting quiz. Are your sources credible? For instance, Uruk is biggest with 40,000 in 3300BC and again with 40-45,000 in 3000BC. But in between it's population has fallen to below 20,000. A similar fate befalls Chang'an in the 8th century AD but with an even less credible fall in population of over 200,000 and bounce-back to where it was before in just 50 years. Also Baghdad in the 10th century. Have you any way of checking?

The issue with the source I used was that it was also according to three different historians opinions. The reason there were such fluctuations in population was because not every source had a city for each of the years - or that city was conquered by a large scale ancient or medieval raid :). Because of this I chose the one that was most believable (or most populated) or if any two sources agreed (these ones are marked in green) I chose that.

So that explains why the data may not be credible, but I tried my best!
