I need to create something kind of like Sim City, but with a little
more fidelity (and no GUI).  I need to model a population of people
over about 100 years, where each person gets married (or not), takes
different jobs, moves, has children, travels, etc.  I have a good
library of monte carlo simulation functions to use, but I don't know
which distributions to use.  I know human populations tend to follow
the normal distribution a lot, but I don't know if others would be
useful; like if people travel according to a Poisson distribution or
something like that.

The key things I am interested in are:

People
Families
Relationships (social, work, family)
Moving
Jobs
Leisure travel
Communication
