They fudge the numbers do to trying an abstract approach. The problem with that is they only do it to the population. They need to fudge the numbers on employment. If they can pack in 370k in such a small area. Why does the commercial jobs number so few.
Also, They should put the sims thought pattern to be to take a job they area actually qualified for. I have problems with them saying they need jobs, but there is job openings for their educational level. It really is annoying to say the least.
At least in Tropico you can just lower the requirements to get a college degree. That way everyone can run a nuclear plant!

Maybe your industry upgraded to a higher tech level, but your workers aren't skilled enough to do those jobs? That happens to me sometimes when I put down a College and the nearby buildings immediately rebuild into higher level tech buildings; however, since I just got the College, no one is skilled enough to do those jobs quite yet.
