More males are born than females, but females live longer. There are only more females than males later in life. Off the top of my head, I can not recall around what age it is that the ratio evens out. (If you wish me to go digging through my books and pull out a textbook reference for this I can.)

But anyhow.... since the figures are used to support polygamy, then let us promote young men to marry much older women-- since that is where the excess of women are!
