US Birth Hint at Bias for Boys in Some Asians

U.S. Births Hint at Bias for Boys in Some Asians
The trend is buried deep in United States census data: seemingly minute deviations in the proportion of boys and girls born to Americans of Chinese, Indian and Korean descent

In those families, if the first child was a girl, it was more likely that a second child would be a boy, according to recent studies of census data. If the first two children were girls, it was even more likely that a third child would be male.
Demographers say the statistical deviation among Asian-American families is significant, and they believe it reflects not only a preference for male children, but a growing tendency for these families to embrace sex-selection techniques, like in vitro fertilization and sperm sorting, or abortion.
New immigrants typically transplant some of their customs and culture to the United States — from tastes in food and child-rearing practices to their emphasis on education and the elevated social and economic status of males. The appeal to immigrants by clinics specializing in sex selection caused some controversy a decade ago.
But a number of experts expressed surprise to see evidence that the preference for sons among Asian-Americans has been so significantly carried over to this country. “That this is going on in the United States — people were blown away by this,” said Prof. Lena Edlund of Columbia University.
She and her colleague Prof. Douglas Almond studied 2000 census data and published their results last year in the Proceedings of the National Academy of Sciences.
In general, more boys than girls are born in the United States, by a ratio of 1.05 to 1. But among American families of Chinese, Korean and Indian descent, the likelihood of having a boy increased to 1.17 to 1 if the first child was a girl, according to the Columbia economists. If the first two children were girls, the ratio for a third child was 1.51 to 1 — or about 50 percent greater — in favor of boys.
Studies have not detected a similar preference for males among Japanese-Americans.
The findings published by Professors Almond and Edlund were bolstered this year by the work of a University of Texas economist, Prof. Jason Abrevaya. He found that on the basis of census and birth records through 2004, the incidence of boys among immigrant Chinese parents in New York was higher than the national average for Chinese families. Boys typically account for about 515 of every 1,000 births. But he found that among Chinese New Yorkers having a third child, the number of boys was about 558.
Joyce Moy, executive director of the Asian American/Asian Research Institute of the City University of New York, said that family values prevalent in China, including the tradition of elder parents depending on their sons for support, have seeped into American culture even among younger immigrants, and even when some of the historic underlying reasons for the preference are less relevant here than in China, Korea and India.
“Inheritance in the old country is carried through the male line,” she said. “Families depend on the male child for support.”
Dr. Norbert Gleicher, medical director of the Center for Human Reproduction, a fertility and sex-selection clinic in New York and Chicago, said that from his experience, people were more inclined to want female children, except for Asians and Middle Easterners.
The preference for males among some immigrant Asians may fade with assimilation, experts said. And no one expects it to result in the lopsided male majorities like those in China, where, according to a study published this year in the British Medical Journal, the government’s one-child policy has resulted in the world’s highest sex disparity among newborns — about 120 boys for every 100 girls.
“The patients come in and they all think they owe me an excuse, but the bottom line is it’s cultural,” said Dr. Jeffrey Steinberg, medical director of the Fertility Institutes, a California clinic that began sex-selection procedures in New York in March.
The Fertility Institutes, which does not offer abortions, has unabashedly advertised its services in Indian- and Chinese-language newspapers in the United States.
“Culturally, there are a lot of strange things that go on in the world,” Dr. Steinberg said. “Whether we agree with it, it’s not harming anyone.”
Efforts by clinics to appeal to Indian families in the United States provoked criticism and some community introspection in 2001. Some newspapers and magazines that ran advertisements promoting the clinics, which offered sex-selection procedures, expressed regret at the perpetuation of what critics regard as a misogynistic practice.
