## Summary

A Galton–Watson process models a population. Each individual has a random number of children, independently of the others and with one common law.
The node [[Galton–Watson process|0H631CZP5K]] gives the precise definition.

## Remarks

The process comes from the study of the extinction of family names by Francis Galton.
