Some Asian families in US choosing sons

Edlund and Almond said they do not know what method is being used for sex selection, but they speculated that the most common is fetal ultrasound to determine the sex of the baby followed by disproportionate abortion of females. Ultrasound has improved in recent years and is being given earlier, they noted.

“Between 1989 and 1999, prenatal ultrasound use among non-Japanese Asian mothers rose from around 38 percent to 64 percent of pregnancies,” they said, citing data from the U.S. National Center for Health Statistics.

The normal sex ratio at birth is 1.05 boys to 1 girl and that holds for first children of these families, the researchers found.

But ifthe first baby is a girl, the odds of a boy coming next rise to 1.17-to-1, and after two sisters the likelihood of having a son jumps to 1.51-to-1.

I know we’re not supposed to say that some cultures are better than others, but…
