The exclusion of never-married women from Chinese fertility surveys.

Never-married women have been regularly excluded in official national surveys of fertility in China, even in light of evidence of increasing premarital sexual activity. Likewise, never-married women in the United States were consistently excluded from national fertility surveys prior to 1982 because of the perceived sensitivity of questions about contraceptive use and sexual activities. Data on sexual and fertility behavior from all women of reproductive age, regardless of marital status, can provide direct measures of sexual activity and unintended pregnancies, as well as facilitate modeling of social networks underlying the sexual transmission of diseases. China's need for such information, however sensitive, will become more difficult to ignore given increasing pressures to attend to the health needs of their never-married but sexually active population.
