Population

One of my teachers provided a interesting insight into the current population size. She summed it up in two of the famous Chinese four character phrases. The first translates as 'more kids, more happiness.' This has had clear effects. However it would be interesting to investigate historical population growth. I'd bet there was a turning point where population growth became exponential. The second phrase translates as 'males are important, females are unimportant.' She gave an explanation for the clear sexism. Traditional when a couple marries the bride moves in with the groom's family in their family compound. As parents grow old, their children take care of them, except if there children were all daughters and married away to other houses. This system has even an greater impact when the parents are limited to one or two children by law.
