During the tutorial before you make a thief it says "Make sure you have enough carriers". I realize this refers to housing/population limit, but I'm clueless as to where I'm supposed to look to see this. I've checked every possible graph and or icon I can find and while I find numbers I don't find anythig indicating whether or not I have enough room for more people. I realize I could count the number of carriers but that's a little tough as everyone looks the same. :P

AOE was always so nice becuase it had a number right in the middle of the top of the screen.
