Probability of Children Being Born at Different Stages of Life Not Equal #1

Open sdpenguin opened 4 years ago

sdpenguin commented 4 years ago

The current model assumes people will have an equal probability of having children throughout their lives.

This should be changed to reflect the average age at which people are most fertile, perhaps with a Gaussian distribution. (People can't have children at 1 year old, and much less likely to have a child at 60 than 30!).

In addition to the different stages of life, the conditional probability of a child being born having already had a child is significantly lower than having had no children. This should be accounted for, or could be approximated by allowing each simulated person to have a maximum number of children in their lifetime.
