Experts Say Slant Toward Male Births Among Asian-American Families Reflects Sex Selection Practices

Research indicating distorted ratios of male to female births among U.S. residents of Chinese, Indian and Korean descent could reflect those families" openness to sex-selection techniques, according to some demographers, the New York Times reports. Historically, male births in the U.S. have led female births by a ratio of 1.05 to 1. A study published last year in Proceedings of the National Academy of Sciences examined 2000 census data and found that among Chinese-, Indian- and Korean-American families, if the first child was a girl, the likelihood that the second child was a boy increased to 1.17 to 1. In addition, if the first two children were girls, the chance that the third was a boy was 1.51 to 1, or about 50% greater than normal. In a study published this year, Jason Abrevaya of the University of Texas examined census data and birth records through 2004, finding that the incidence of boys as third children among immigrant Chinese parents in New York was 558 of every 1,000 births, significantly higher than the national average of 515. Many experts were surprised at the evidence that the cultural preference for sons among some Asian cultures has carried over to immigrants in the U.S., the Times reports. Studies have not demonstrated a slanted proportion of male births among Japanese immigrants, according to the Times. According to demography experts, the deviation toward male births among some Asian-American immigrants reflects both a cultural preference for boys and an increased tendency for families to seek out sex-selection techniques such as in vitro fertilization, sperm sorting or abortion. Some clinics that offer IVF or sperm sorting to select for sex market their services to Asian-American families through advertisements in Indian- and Chinese-language newspapers. In 2001, criticism arose within the Indian-American community about clinics targeting that population, and some community newspapers and magazines expressed regret for publishing advertisements that critics said were perpetuating a misogynistic practice. Joyce Moy, executive director of the Asian American/Asian Research Institute of the City University of New York, said that younger Chinese immigrants have adopted the family values that are common in China -- such as the tradition of elders depending on their sons for support -- even though some of the reasons behind those customs are less relevant in the U.S. Experts say that the preference for male children may fade with further assimilation, the Times reports.In China, sex selection typically is achieved through abortion of female fetuses. Although doctors say the practice also occurs in the U.S., few families discuss it, the Times reports. Lisa Eng, a Hong Kong-born gynecologist who practices in New York City"s Chinatown and Brooklyn, said that she attempts to discourage couples who prefer boys from having abortions. "If it"s going to be a third [child], they"re pretty determined to have a boy," she said, adding, "If it"s a boy, they keep it. If it"s a girl, they"ll abort" (Roberts, New York Times, 6/15).
