The Implementation of Preferences for Male Offspring

Abstract

Over the past quarter century the sex ratio at birth (SRB) has risen above natural levels in a number of countries, mostly in Asia. This rise has been made possible in populations with strong son preference by the increasing availability of safe, effective, and inexpensive technologies to determine the sex of a fetus and to end unwanted pregnancies. This article documents levels and trends in the sex ratio at birth, in preferences for male offspring (using information on desired number of girls and boys), and in the implementation of these preferences. DHS surveys from 61 countries in Africa, Asia, and Latin America and for Indian states are the main source of data. A comparison of desired with actual SRBs finds large gaps in most populations, implying a substantial pent‐up demand for male offspring and the technology to implement this preference. Two types of actions to implement preferences are considered: the practice of contraception to stop childbearing after the desired number of sons has been born and the use of sex‐selective abortion to avoid female births. The second part of the article discusses factors that could influence the SRB, including the promotion of gender equality, and the implications of these factors for future trends.

How could differences in ‘control over destiny’ lead to socio-economic inequalities in health? A synthesis of theories and pathways in the living environment

“…As well as having a direct effect on the survival chances of female foetuses, girls and women, commentators warn of wider societal impacts of having fewer women than normal in the adult population, including, in China in particular, having millions of men without spouses or children. The posited consequences include increased risks of coerced marriage, bride abduction, trafficking of women and girls, sexual exploitation and violence across communities (Bongaarts, 2013).…”

“…The summary statistics in Table 1 show that the two subsamples are balanced in all regards, except that the male subsample is larger and the females have more siblings, which is consistent with sex-selective stopping rules by which parents seek additional children until they reach their desired number of boys (Bongaarts, 2013). Note: Summary statistics pertain to all observations included in regressions (every measured child aged 12-59 months).…”

On the masculinization of population: The contribution of demographic development -- A look at sex ratios in Sweden over 250 years

“…In countries or regions that experience imbalance in the sex ratio at birth due to the implementation of cultural preferences for male offspring (Bongaarts 2013;Guilmoto 2015), the continuing reduction of mortality at infant and child ages and later in life will have implications for the sex ratios in the population. With continuing survival gains at all ages, the larger (imbalanced) proportion of male births will be prolonged later in life and contribute to further exacerbate the imbalance between the sexes in older age groups and in the population in general.…”
