Using data from the 1982 National Survey of Family Growth (NSFG), this analysis reports differentials in contraceptive discontinuation among married women aged 15-44 years in the United States. The total discontinuation rate is broken down into change to no method (termination) or to a different method (a method switch), and rates are obtained for specific methods. In addition, sociodemographic differences in risks associated with each type of discontinuation are shown. Discontinuation rates are compared to use-failure rates to provide a more comprehensive understanding of the implications of discontinuation for contraceptive efficacy.
This study examines contraceptive method switching among married women in the US. It enquires first into the effect of method type and women's socioeconomic characteristics on the risk of switching to each of six methods, including no method, and secondly into the previous methods used by women who adopt specific contraceptive means. The results indicate a great deal of circulation among all method types and of movement to unprotected intercourse. The adoption of sterilization is greatest among women not previously using any contraceptive method.
Data from the National Panel Study are used to investigate occupational choices and migration status among a sample of U.S. white farm boys in the late 1800s. Originally sampled when 5 to 14 years old in 1880, these boys are traced to the 1900 census when they were young adults. In general, the decision to leave farming was related to the urban-industrial “pull” of the surrounding environment and the degree of farm mechanization of the community. While migratory behavior correlates positively with occupational change, the major social correlates are somewhat different. Variations in migration are not strongly related to the urban-industrial and agricultural environments. Rather, variables measuring the probability of farm inheritance emerge as stronger predictors.

Originally sampled when 5 to 14 years old in 1880, these boys are traced to the 1900 census when they were young adults. In general, the decision to leave farming was related to the urban-industrial "pull" of the surrounding environment and the degree of farm mechanization of the community. While migratory behavior correlates positively with occupational change, the major social correlates are somewhat different. Variations in migration are not strongly related to the urbanindustrial and agricultural environments. Rather, variables measuring the probability of farm inheritance emerge as stronger predictors.The evolution of high-technology societies involves a number of major social changes. Two of the most ubiquitous are the decline in farming as an occupation and the increasing urbanization of the population. The reasons for these changes are undoubtedly numerous, but basically they relate to the greater economic opportunities in cities and the increasing ability of the agricultural work force to utilize production technology so effectively that it eliminates the need for human labor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
