A few minor things I noticed that could use some tweaking:
1. The Demographics screen needs some recalibration regarding the Soldier numbers. I don't think 400 population can support 104,000 soldiers.

The population reported is incorrect. When you look at the city population (not size) you see a number that scales very non-linearly from city raw size. However, this screen (I think - need to check the code sometime) just totals the raw city sizes. It needs to total the converted population numbers. It's cosmetic, so not something I am going to regard as a priority, but I doubt it's terribly hard to address.
Edit - I take it back. Population is fine. As you initially stated, it's early troop numbers that are amiss.
Edit 2 - it's actually rather hard to address, since the number reported as 'soldiers' is actually 'Power' for the civ in question. This is made up of contributions from population, buildings, and units which are hard to untangle. Not going to mess with it for now. Simplest solution would be to just rename the row 'Power' rather than 'Soldiers' (it's called Power on the graphs tab already).
