What's the lifecycle of a Tropico citizen?

Here's a simple question that I just have not been able to eyeball - What's the life-cycle of a citizen in Tropico? As in:

• At what age are they babies?
• At what age are they children (and does a grade school affect this)?
• At what age are they able to attend high school/get a job?
• At what age can Tropicans get married?
• At what age can women become mothers?
• At what age do they retire?

I can't find anything anywhere that has even basic information about Tropican life-cycles!
