Is there an explanation of the demands system?
In my 3th game i was building a little town and noticed that the demand for commercials aren't increasing. Over the last 7 years the amount of people working in commerce didn't changed, by permanent increasing population. There is still enough space for new commerce and even abandoned buildings, but they don't show any interest. At least the demand for industry is higher than normal so that they can work there.
Education level? Maybe compare the population with industry and see if theres a correlation.
My question, where is this statistics tab?
