A further problem with this is that it also assumes that children are literally that, ie. they are considered to be legally considered as children.

In the field of human genetics (in which I work), off-spring are considered, thus you may have a patriarch and matriarch, but be interested in how many off-spring (ie. children) they have, who may actually be older than 18.

Pedantic, but sometimes important depending on how you are defining 'children'.
