Since first cousins are those who share one set of same grandparents, it
really comes down to knowing the average number of children (who had
offspring of their own) for each generation. If the average number of
children in my grandparents' generation was 3, and the average number of
children in my parents' generation was 2, then there should be an
average of 6 persons in my generation who share one set of grandparents.
This number goes up fast when you get to second cousins (who share a
set of great-grandparents). Assuming the average number of procreating
offspring in my great-grandfathers' generation was 4, then the average
number of second cousins in my generation would be 4x3x2 = 24 (but six
of those would actually be the first cousins). I'm sure there are other
factors that I have not considered, but that would be a rough
calculation. Of course, eventually you find out that we are all cousins
to some degree.
