The rising incidence of premarital pregnancy is largely an indication of the rapid change of the attitudes and practices about sex and marriage in China．Pregnancies ended with abortion also imply new threats to women’ s health and development．Based on discussing the data bias and theoretical shortages in past research，we propose new frames to measure and analyze this problem．Using data from the 2013 National Floating Population Dynamic Monitoring Survey we examine age，peri- od，and cohort trends in premarital pregnancy，and test hypotheses about the effect of migration．Re- sults show that younger cohorts have higher incidence of premarital pregnancy promoted by migration， especially for the rural migrants and those with lower education．We suggest to collect more data on premarital sex behavior and pregnancy，and to offer family planning services for the youth and adults who have not yet married．

Using couple-paired sample survey data collected by Beijing Academy of Social Construction in Renmin University of China, the article analyzes the relationship between subjective well-being and relative occupational position of couples from the perspectives of family rights and status theory and role conflict theory. The results show that the self-identified relative occupation relative position has significant influence on family well-being. Higher relative occupation status of husband is significantly associated with higher family well-being and better intergenerational relationships. Couples’ occupational relative position has both direct and indirect effect on family well-being. Comparing with other types of families, couples in the family with wife having relatively higher occupational position are significantly less happy, and the intergenerational relationships are worse. Wife’s satisfaction on her leisure and husband’s satisfaction on his work are positively associated with their happiness.
