This paper examines social class differences in fertility, using longitudinal micro-level data for a regional sample in Sweden, 1922–2015. Using discrete-time event history models, we estimated the association between social class and parity-specific duration to next birth, adjusting for household income in separate models. Social class was associated with fertility quite independently from income and the association was both parity-dependent and sex-specific. For transitions to parenthood, higher class position was associated with higher fertility for men and lower fertility for women before 1970, but then converged into a positive association for both sexes after 1990. For continued childbearing, a weak U-shaped relationship before 1947 turned into a positive relationship for second births and a negative relationship for higher-order births in the period after 1990. These patterns likely reflect broader changes in work–family compatibility and are connected to profound shifts in labour markets and institutional arrangements in twentieth-century Sweden.

The Own Children Method (OCM) is an indirect procedure for deriving age-specific fertility rates and total fertility from children living with their mothers at a census or survey. The method was designed primarily for the calculation of overall fertility, although there are variants that allow the calculation of marital fertility. In this paper we argue that the standard variants for calculating marital fertility can produce misleading results and require strong assumptions, particularly when applied to social or spatial subgroups. We present two new variants of the method for calculating marital fertility: the first of these allows for the presence of non-marital fertility and the second also permits the more robust calculation of rates for social subgroups of the population. We illustrate and test these using full-count census data for England and Wales in 1911. [ABSTRACT FROM AUTHOR]

Hong Kong is characterized by very low fertility. However, over a period from 2000 to 2015, both the total number of births and the sex ratio at birth (SRB) increased and then declined dramatically. We analysed the increases in a 2013 paper in this journal, where we largely ascribed them to a rapid growth in the number of 'transient' mothers from Mainland China disproportionately giving birth to boys in the territory. In 2012, policies were implemented to halt this 'maternity migration'. Here, we explore the impact of these policies, both on births and the SRB in Hong Kong. We conclude that the rises and falls in births and SRBs in Hong Kong can, indeed, be broadly ascribed to the reproductive behaviour of transient Mainland mothers. However, the role of the Hong Kong government's policy interventions is much less clearly defined. [ABSTRACT FROM AUTHOR]

The timings of historical fertility transitions in different regions are well understood by demographers, but much less is known regarding their specific features and causes. In the study reported in this paper, we used longitudinal micro-level data for five local populations in Europe and North America to analyse the relationship between socio-economic status and fertility during the fertility transition. Using comparable analytical models and class schemes for each population, we examined the changing socio-economic differences in marital fertility and related these to common theories on fertility behaviour. Our results do not provide support for the hypothesis of universally high fertility among the upper classes in pre- transitional society, but do support the idea that the upper classes acted as forerunners by reducing their fertility before other groups. Farmers and unskilled workers were the latest to start limiting their fertility. Apart from these similarities, patterns of class differences in fertility varied significantly between populations.
