The Science of Sex Ratios

Satoshi Kanazawa has written a series of blog entries on what determines the sex ratio in humans. It is fascinating stuff:

  • engineers and scientists are more likely to have sons
  • nurses and social workers are more likely to have daughters
  • big and tall parents are more likely to have sons
  • violent parents are more likely to have sons
  • beautiful parents are more likely to have daughters
  • sexually promiscuous parents have more sons

You can read the underlying articles here, here, here, and here.
