Demography's theory and approach: (How) has the view from the margins changed?

Around the time that Population Studies celebrated its 50th anniversary in 1996, Susan Greenhalgh published 'An intellectual, institutional, and political history of twentieth-century demography'. Her contribution described a discipline that, when viewed from its margins, prompted scholars in other disciplines to ask the following questions: 'Why is the field still wedded to many of the assumptions of mid-century modernization theory and why are there no critical … perspectives in the discipline?' (Greenhalgh 1996, p. 27). Those questions still arise today. Similarly, Greenhalgh's observation that 'neither the global political economies of the 1970s, nor the postmodernisms and postcolonialities of the 1980s and 1990s, nor the feminisms of any decade have had much perceptible impact on the field' (pp. 27-8), remains a fairly accurate depiction of research published in Population Studies and other demography journals. In this contribution, focusing predominantly on feminist research and insights, I discuss how little has changed since 1996 and explain why the continued lack of engagement concerns me. Demographers still often fail to appreciate the impossibility of atheoretical 'just descriptive' research. Our methods carry assumptions and so rely on (often) implicit theoretical frameworks. Not making frameworks explicit does not mean they do not exert an important influence. I end by proposing that the training of research students should be part of a strategy to effect change.

Mind the gap: The health advantages that accompany parental marriage vary by maternal nativity.

Using data from the UK Millennium Cohort Study (MCS), we examine whether and how the health benefits of having two biological parents in a continuous marital relationship vary by maternal nativity and ethnicity, comparing UK-born White mothers with: (1) White mothers born in wealthy countries; (2) ethnic minority mothers from South Asia; and (3) ethnic minority mothers born in Africa. Making novel use of classification and regression tree (CART) methods, we examine whether marital status is a uniform marker of economic advantage or better health-related behaviours across the four maternal nativity and ethnic groups. The findings, which indicate that the health-related advantages associated with parental marriage are not uniform across the four nativity and ethnic groups, have implications for future research on family gaps in well-being and the socio-economic determinants of health.

When richer doesn't mean thinner: Ethnicity, socioeconomic position, and the risk of child obesity in the United Kingdom.

BACKGROUND: A range of studies report a robust association between family socioeconomic position and the prevalence of child overweight/obesity. On average, children from poorer backgrounds are more likely to be overweight/obese than children from more advantaged families. However, a small number of US studies have shown that, for ethnic minority children, the association is either nonexistent or reversed. OBJECTIVE: We test if the link between socioeconomic position and child overweight/obesity at age 7 is heterogeneous in the United Kingdom where rates of obesity are particularly high for some groups of ethnic minority children. METHODS: We use nationally representative data from the UK Millennium Cohort Study as well as descriptive analyses and logistic regression models. RESULTS: Poorer White children are at higher risk of overweight/obesity than higher income White children. However, socioeconomic disparities are reversed for Black African/Caribbean children and nonexistent for children of Indian and Pakistani/Bangladeshi origin. Moreover, the health behaviours that explain socioeconomic disparities in child overweight/obesity for the White group appear to be irrelevant in explaining differences by socioeconomic position for the Black Caribbean and African groups. CONCLUSIONS: We should be careful in assuming that higher socioeconomic position is protective against child overweight/obesity for all groups of the population. CONTRIBUTION: This study shows for the first time important variation by ethnicity in the link between socioeconomic position and child overweight/obesity - and in the underlying mechanisms linking them - in the United Kingdom.

Gender and the Politics of Death: Female Representation, Political and Developmental Context, and Population Health in a Cross-National Panel.

There is considerable speculation that female political empowerment could improve population health. Yet, evidence to date is limited, and explanations for why political empowerment would matter and the conditions under which this might be enhanced or muted are not well understood. In this article, we draw on theoretical work on the politics of representation to frame an investigation of whether increases in the percentage of females in a country's parliament influence mortality rates. We further examine whether the relationship is conditioned by extent of democracy and economic and social development. Through multivariate longitudinal regression, we analyze four indicators of mortality in 155 countries spanning 1990 to 2014 with controls for initial country conditions, time-stable structural predispositions to higher mortality, and a number of time-varying potential confounders. Results indicate that a high level of female representation-30 % or greater in our models-has large negative associations with mortality, that these are particularly strong in lesser developed and weak democratic contexts, that high female political representation effectively offsets liabilities associated with low development, and that the relationships are robust to various operationalizations of social development. In the end, our research provides a particularly thorough accounting of the relationship between female political representation and population health, particularly by specifying the conditions under which female representation is most salient. In doing so, the research suggests important links between issues of female empowerment, political context, and developmental trajectories of countries more generally.

When the grass is greener: Fertility decisions in a cross-national context.

In research and policy discourse, conceptualizations of fertility decision-making often assume that people only consider circumstances within national borders. In an integrated Europe, citizens may know about and compare conditions across countries. Such comparisons may influence the way people think about and respond to childrearing costs. To explore this possibility and its implications, we present evidence from 44 in-depth interviews with Polish parents in the United Kingdom and Poland. Explanations of childbearing decisions involved comparisons of policy packages and living standards across countries. Individuals in Poland used richer European countries as an important reference point, rather than recent conditions in Poland. In contrast, migrants often positively assessed their relatively disadvantaged circumstances by using the Polish setting as a reference. The findings could help explain why, despite substantial policy efforts, fertility has remained at very low levels in poorer European countries, while migrants from those countries often have higher fertility abroad.
