I personally don't find any of the information you've posted to be of any use. I was looking to find out why the data isn't showing the correct info when I get more people. I mean the schools show uneducated sims but the data map show unenrolled sims. I've placed loads of busses in every high school and primary school I can find, but none go to my schools. Another thing is now peaking my interest is the sims traveling to other cities. It would be nice to have another way to travel to a city in this game. Subways or mas transport vehicles that travel by air and sea. The ferries and hot air balloons aren't enough. air ports only work if there are air ports to travel to. It would also be nice if Sims that are tour my cities would eventually move into a home as well.
But this leads to how the data is calculated. I mean the percentage is off. So I suggest that it be per person has a chance to be a kid or adult. if adult, then works. period. if a kid then it should go into schools and stay in your city till they move. but the data should reflect how much opportunity there is in your city to move up in the SimCity world.
