We explore the demographic factors contributing to China's unbalanced sex ratio at marriagable ages. We develop a stable population model of the sex ratio at marriagable ages, and compare a series of population projections with alternative underlying assumptions about the key demographic inputs. The stable population model demonstrates that several demographic factors interact to influence the sex ratio at marriagable ages, including the sex ratio at birth, population growth, the age gap of marriage partners, and the sex ratio of survival from birth to marriageable age. The population projections further demonstrate that policies that seek to reduce the sex ratio at birth and the age gap at marriage and, to a lesser extent, increase fertility would be most effective at alleviating the problem. But no demographic changes are likely to occur quickly enough to balance the sex ratio at marriagable ages in the near future.
The accuracy of counts of U.S. racial/ethnic and immigrant groups depends on coverage of the foreign-born in official data. Because Mexicans constitute by far the largest single national-origin group among the foreign-born in the United States, we compile new evidence about the coverage of the Mexican-born population in the 2000 census and 2001–2010 American Community Survey (ACS) using three techniques: a death registration, a birth registration, and a net migration method. For the late 1990s and first half of the 2000–2010 decade, results indicate that coverage error was somewhat higher than currently assumed but substantially declined by the latter half of the 2000–2010 decade. Additionally, we find evidence that U.S. census and ACS data miss substantial numbers of children of Mexican immigrants, as well as people who are most likely to be unauthorized: namely, working-aged Mexican immigrants (ages 15–64), especially males. The findings highlight the heterogeneity of the Mexican foreign-born population and the ways in which migration dynamics may affect population coverage.
Although the consequences of the Great Recession are extensively discussed in previous research, three critical issue need to be addressed in order to develop a full portrait of the economic experiences of children during this period. First, given the changing immigrant composition of the US child population, new studies are needed for examining the implications of immigrant status for exposure to child poverty during the recession. Second, it is important to understand how traditional patterns of racial inequality among were transformed during the years of the recession. Finally, it is not clear whether recession-related changes in socioeconomic inequalities continued to have implications for child well-being in the post-recession period. Results from this analysis indicate that the adverse effects of the recession were most intense in states with significant changes in their populations of Black and Latino immigrant children. The results further show that declines in parental work opportunities were more consequential for poverty among Whites and Asians. The analysis also finds differential implications of family contexts for child poverty among Black immigrant and natives during the recession. Finally, the results indicate that increases in racial child poverty disparities during the recession did not disappear in the years following the downturn.
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.
