More Demography tidbits

The General Fertility Rate:

Number of children born/Person-years for women aged 15-50 (reproductive interval)

For the Donaldsons 2009-2012:

10/ 6*3= .56

For the Cranneys:

6/5*3= .4

1985-1990 France: .0059
1985-1990 Zaire: .2173

So, according to this one indicator, the Cranneys and Donaldsons have more than twice the fertility rate of a sub-Saharan African country, and more than ten times the fertility rate of France. Of course, this isn't a terribly accurate comparison, since in a normal population there is some variation within the 15-50 range, so the 15 and 50-year olds drag down the overall rate (although Catherine acts as the token 15-year old here), but it's still interesting.

One more thing for me to be grateful for today--that my 15 year old is dragging down the overall rate of this statistic. :-)

How would the numbers go for the Nielsens? 3 women, 8 kids? Just wondering if the * is multiplication? Thanks, Interesting!

Looks like your quest for world domination is coming to fruition.

It's good to know that we are keeping up with Africa and leaving France in the dust.
