RENEE MONTAGNE, host:
When reporter Mara Hvistendahl traveled to Suining County in China, she found a booming economy, apartment buildings decorated with Roman columns, supermarkets selling jewelry and watches next to produce. And, at an elementary school, she saw students assembled in two straight lines like the children in the book "Madeline" - except these kids were overwhelmingly male.
STEVE INSKEEP, host:
Hvistendahl discovered there were twice as many boys as girls. Mara Hvistendahl writes about this in her new book, "Unnatural Selection: Choosing Boys Over Girls and the Consequences of a World Full of Men." She cites a widely accepted figure - if sex ratios at birth had stayed normal over the past few decades, there would be 163 million more females in Asia.
MONTAGNE: Preferring baby boys to baby girls isn't a new phenomenon. What's different, she says, is that parents in developing countries can now put that preference into action far more easily.
Ms. MARA HVISTENDAHL (Author, "Unnatural Selection: Choosing Boys Over Girls and the Consequences of a World Full of Men"): As a country develops, birth rate falls, and new technology comes in, and, unfortunately, one of the side effects is skewed sex ratio at birth.
MONTAGNE: Well, I think there will be a lot of people listening who will think wait a minute, in these countries, women, families, couples rather, don't have really good access to sex selection technologies. You know, it's expensive, they have to go to a city, but that's not true.
Ms. HVISTENDAHL: One thing that's key to remember, is this is happening among educated women with more resources, more money. At the same time, there are cheap ultrasound machines available, and then also there's a very different context surrounding abortion in Asia. You know, in the U.S., a woman may have to brave picket lines to get an abortion. She may not have a clinic in her town. And in many parts of Asia, abortion's readily available and so is ultrasound.
MONTAGNE: Can this be entirely attributed to prejudice against girls? Because, what seems unusual about this, is you're talking about richer societies with women who are more highly educated - and yet it's turning into a drastically bad situation for fetuses that are female.
Ms. HVISTENDAHL: So, looking at gender discrimination alone, doesn't explain the problem, because in many societies around the world, parents tell researchers they want at least one boy. And you have countries where women have very low status, in the Middle East for example, and the sex ratio at birth is balanced. That just really does not explain what's happening.
MONTAGNE: What does explain what's happening?
Ms. HVISTENDAHL: Well birth rates, again, have fallen very dramatically. If you look at the average Korean woman, in the 1950s, had six children. Now the birth rate is close to one. And that's a very dramatic fall. If you have six children, the chance that one of those children will turn out to be a boy is 99 percent. So it's not that women necessarily want sons any more than before, but there's more pressure on them. And these countries also have a history of population control a dark history, at that.
MONTAGNE: So give us an example of what it means for a country or region to have more boys. One of the big examples in your book is Taiwan.
Ms. HVISTENDAHL: Taiwan was one of the earlier countries to practice sex selection, and today you have this whole generation of men that are having trouble finding wives. And there are these marriage tours, they're called, that have developed, where a man can pay $10,000 and he gets a flight, room and board, and the fee includes the price of a wife.
MONTAGNE: Put in perspective how many missing women there are, or the reverse, how many bachelors there are who cannot easily find a bride nearby as they traditionally would, a Taiwanese bride.
Ms. HVISTENDAHL: Well, to give you a sense of how many men are going on these tours, in parts of rural Korea and Taiwan, about 40 percent of men are marrying women from foreign countries, and almost all of them are turning to matchmakers. In China and India you'll have 15 percent of men, over the next few decades, who will lack female partners. And so, that is a very grave issue in those countries.
MONTAGNE: And what does that mean for the society?
Ms. HVISTENDAHL: We do know that unmarried men are responsible for more crime and more violent crime than married men. And there has been one study that was done in eastern China, that showed the sex ratio at birth didn't rise in all parts of China at the same time. So economists looked at the areas where people started having more boys earlier, and then compared that against the crime rate. And what they found is that the increase in sex ratio in birth actually contributed to the crime rate - and greatly.
MONTAGNE: There was a distinction correlation.
Ms. HVISTENDAHL: There was a correlation between the crime rate and the gender imbalance in eastern China.
MONTAGNE: Why didn't this gender imbalance happen in more developed countries, earlier, when they had access to things like ultrasound and amino-synthesis, things that tell you want the sex of the unborn child is?
Ms. HVISTENDAHL: Well, in the West we don't have the same history of population control that they do in Asia. At the same time, ultrasound technology has only been at the point where we've been able to determine the sex of the fetus early on, since the 1980s. You know, we hit development much earlier. But Americans do, today, actually select for sex during in vitro fertilization.
MONTAGNE: And does that favor boys?
Ms. HVISTENDAHL: Well, the directors of fertility clinics say that Americans prefer girls. But, I actually think American's selecting for girls is really not that different from what's happening in Asia. In both cases, parents are going in with a kind of preconceived notions about how the child is going to turn out, and it's really in both places shift toward consumer ugentics, toward parents making small decisions over how their child's going to turn out. And, you know, you add those decisions up and you have an impact on society.
