this is not a journal title

sorry to repeat if you saw when i blogged this at the time, but, although i generally thought that book was pretty good, i was really bothered by the poorly thought-out population dynamics. they say that each designated child-bearing woman bears exactly three children, and that the designated child-bearers are excluded from high-status jobs, and i think it's at least implied that the sex ratio of the population is 1:1. but these numbers would require that, in order to maintain a stable population, about 2/3 of the women in the society would need to be designated child-bearers. only we don't see a society with those gender dynamics - it's strongly implied that most little girls are looking forward to the prospects of other jobs. it's not relevant the main concerns of the book, but the way it apparently wasn't thought out still bothers me.
