Effects of gender, birth order, and other correlates on childhood mortality in China.
Using data from the 1988 Two-Per-Thousand Survey of Fertility and Birth Control, this paper examines the effects of gender, birth order, and other correlates of childhood mortality in China. Controlling for family-level factors, childhood mortality is found to be associated with the child's gender and birth order. Among firstborn children the difference between male and female childhood mortality is not statistically significant, but among others, female children between ages 1 and 5 experience higher mortality than male children. Childhood mortality is slightly higher for children who have older brothers only than for those who have older sisters only, and it is highest for those who have both older brothers and sisters. Other factors affecting childhood mortality in China include mortality of older siblings, birth interval, urban/rural residence, mother's level of education, and mother's occupation. All interactive effects between gender and family-level characteristics are found to be statistically insignificant.

Why do Chinese women practice contraception? The case of rural Jilin Province.
This study focuses on the relationship between contraceptive behavior, family size preferences, and perceptions of the one-child policy among young Chinese women in rural areas of Jilin Province. In 1985, about 85 percent of rural married women with one surviving child were practicing contraception, although most of them reported two as their ideal number of children. Most women with one surviving child, including those with one-child certificates, were practicing contraception in response to the government campaign, while more than half of women with two or more children were doing so voluntarily. Most of the women with one child were using the IUD, whereas more than half of women with two or more children were sterilized. Through multivariate analysis of contraceptive behavior and method choice, additional factors were found to be associated with the contraceptive behavior of rural Jilin women; achievement of their ideal family size was a significant factor in the voluntary practice of contraception as well as in contraceptive method choice. Implications of the results are discussed.

Infant mortality trends and differentials in Nepal.
Infant mortality trends and differentials are estimated from the 1981 Nepal Contraceptive Prevalence Survey (NCPS) and compared with similar estimates from the 1976 Nepal Fertility Survey (NFS) and the 1981 Census of Nepal. The analysis indicates that infant mortality rates derived directly from the NFS maternity histories are the most accurate. Infant mortality rates derived directly from the NCPS maternity histories are severely underestimated and yield a strongly biased trend that is the reverse of the true downward trend. Indirect estimates of infant mortality trends derived from child survivorship data do not result in a consistent pattern. Infant mortality differentials, when expressed in relative rather than absolute terms, are generally consistent with findings from earlier studies. Possible reasons for data quality differences among the three data sources are discussed.

Evaluation of contraceptive history data in the Republic of Korea.
The consistency of retrospective and current status data on contraceptive use from a series of national fertility surveys carried out during the 1970s in Korea is investigated. Aggregate consistency is examined among random samples from the same cohort or cohorts of women interviewed in each survey. The results indicate that estimates of trends in contraceptive use from a retrospective history in one survey, or from cross-sectional estimates in a series of surveys, can each yield misleading findings. Data from the 1974 Korean National Fertility Survey (KNFS) appear to be more reliable than those from other surveys, possibly because an interval-by-interval contraceptive history was used, explicit definitions of contraceptive methods were given prior to taking the contraceptive history, and the KNFS involved longer interviewer training and, perhaps, less time pressure during interviews.
