Quantifying the postponement in the age at first attempt to conceive and its consequences
The substantial rise in the age at first birth in recent decades suggests that people are delaying their first attempt to have a child. The age at first birth, however, may not accurately reflect when people first attempt to conceive, given age-related declines in the ability to get pregnant and to achieve a live birth. Through a microsimulation model incorporating biological parameters and sequential Approximate Bayesian Computation, we estimate…
Examining the relationships between education, coresidential unions, and the fertility gap by simulating the reproductive life courses of Dutch women
BACKGROUNDCouples in Europe have fewer children than they intend to, resulting in a gap between intended family size and completed fertility.This is partly because first-pregnancy attempts are postponed to older reproductive ages, when giving birth is more difficult due to the decline in fecundity and increased probability of miscarriage.Modelling educational differences in prevalence, timing, and stability of coresidential unions together with r…
Understanding Narratives of Uncertainty in Fertility Intentions of Dutch Women
Uncertainty in fertility intentions is a major obstacle to understanding contemporary trends in fertility decision-making and its outcomes. Quantifying this uncertainty by structural factors such as income, ethnicity, and housing conditions is recognized as insufficient. A recently proposed framework on subjective narratives has opened up a new way to gauge factors behind fertility decision-making and uncertainty. Through surveys, such narratives…
Fertility preferences in China in the twenty-first century
There is continuing debate on how low China’s fertility has reached and whether China has fallen into the “low fertility trap”. This paper addresses this debate by revisiting the trends in fertility preferences in the past decades in China based on a meta review. Moreover, the analysis contrasts distinct measurements of fertility preferences to capture different aspects of reproductive decision-making. This papers reviews 152 studies resulting in…
Simulating the evolution of height in the Netherlands in recent history
The Dutch have a remarkable history when it comes to height. From being one of the shortest European populations in the 19th Century, the Dutch grew some 20 cm and are currently the tallest population in the world. Wealth, hygiene, and diet are well-established contributors to this major increase in height. Some have suggested that natural selection may also contribute to the trend, but evidence is weak. Here, we investigate the potential role of…
Describing the Dutch Social Networks and Fertility Study and how to process it
BACKGROUND The social networks of people play a prominent role in theories on fertility. Investigating how networks shape behaviour is hard, because of the difficulty in measuring (large) networks among representative samples. Therefore, comprehensive studies of the variation in the structure and composition of networks and their impact on fertility outcomes are lacking. OBJECTIVE I aim to, first, describe the Dutch Social Networks and Fertility …
Friends, family, and family friends
Friends are an important source of well-being but people differ in who they consider to be friends. With a unique quantitative test of such differences based on 17,650 social relations of 706 Dutch women (aged 18-41), of whom 40% were considered friends, we examined (a) which kind of personal relations were typically identified as friends (e.g., family, colleague), (b) how this linked to relationship closeness, face-to-face and non-face-to-face c…
Balancing bias and burden in personal network studies
Do Data from Large Personal Networks Support Cultural Evolutionary Ideas about Kin and Fertility
The fertility decline associated with economic development has been attributed to a host of interrelated causes including the rising costs of children with industrialization, and shifts in family structure. One hypothesis is that kin may impart more pro-natal information within their networks than non-kin, and that this effect may be exacerbated in networks with high kin-density where greater social conformity would be expected. In this study, we…
Collecting large personal networks in a representative sample of Dutch women
In this study we report on our experiences with collecting large personal network data (25 alters) from a representative sample of Dutch women. We made use of GENSI, a recently developed tool for network data collection using interactive visual elements that has been shown to reduce respondent burden. A sample of 758 women between the ages of 18 and 40 were recruited through the LISS-panel; a longitudinal online survey of Dutch people. Respondent…
ESMvis
ESMvis is a showcase on providing personalized feedback by dynamic visualization of ESM time-series data. Our tool is freely available and adjustable, making it widely applicable. In addition to potential applications in clinical practice, ESMvis can work as an exploratory tool that can lead to new hypotheses and inform more complex statistical techniques
Three facets of planning and postponement of parenthood in the Netherlands
The age at parenthood has risen by about five years in the last decades in the Netherlands. Previous studies typically focused on the age at which people have their first child, but little is known about desired timing of parenthood and how this desire cha
Using Polygenic Scores in Social Science Research
Biological, genetic, and socio-demographic factors are all important in explaining reproductive behavior, yet these factors are typically studied in isolation. In this study, we explore an innovative sociogenomic approach, which entails including key socio-demographic (marriage, education, occupation, religion, cohort) and genetic factors related to both behavioral [age at first birth (AFB), number of children ever born (NEB)] and biological fecu…
Evolutionary Psychology
Although the term “evolutionary psychology” would appear both simple and self‐explanatory, suggesting a rather straightforward application of evolutionary theory to both human and nonhuman psychology, appearances can be deceptive. The status of the discipline and its recent history are far from straightforward, and debates between various schools of thought have been rather fraught at times. This entry lays out the origins of evolutionary psychol…

Hidden heritability due to heterogeneity across seven populations
Meta-analyses of genome-wide association studies, which dominate genetic discovery, are based on data from diverse historical time periods and populations. Genetic scores derived from genome-wide association studies explain only a fraction of the heritability estimates obtained from whole-genome studies on single populations, known as the ‘hidden heritability’ puzzle. Using seven sampling populations (n = 35,062), we test whether hidden heritabil…

Evolutionary perspectives on human height variation
Human height is a highly variable trait, both within and between populations, has a high heritability, and influences the manner in which people behave and are treated in society. Although we know much about human height, this information has rarely been brought together in a comprehensive, systematic fashion. Here, we present a synthetic review of the literature on human height from an explicit evolutionary perspective, addressing its phylogenet…
The Reproductive Ecology of Industrial Societies, Part II
Studies of the association between wealth and fertility in industrial populations have a rich history in the evolutionary literature, and they have been used to argue both for and against a behavioral ecological approach to explaining human variability. We consider that there are strong arguments in favor of measuring fertility (and proxies thereof) in industrial populations, not least because of the wide availability of large-scale secondary dat…
The Reproductive Ecology of Industrial Societies, Part I
Is fertility relevant to evolutionary analyses conducted in modern industrial societies? This question has been the subject of a highly contentious debate, beginning in the late 1980s and continuing to this day. Researchers in both evolutionary and social sciences have argued that the measurement of fitness-related traits (e.g., fertility) offers little insight into evolutionary processes, on the grounds that modern industrial environments differ…
Fertility Theory
Taking the aggravation out of data aggregation
Field data often include multiple observations taken from the same individual. In order to avoid pseudoreplication, it is commonplace to aggregate data, generating a mean score per individual, and then using these aggregated data in subsequent analyses. Aggregation, however, can generate problems of its own. Not only does it lead to a loss of information, it can also leave analyses vulnerable to the "ecological fallacy": the drawing of false infe…
Finding your Soulmate
Heterosexual age preferences have been extensively studied by evolutionary psychologists, social psychologists, and demographers. Much less is known about such preferences in homosexual men and women. Around two decades ago, D. T. Kenrick, R. C. Keefe, A. Bryan, A. Barr, and S. Brown (1995) examined heterosexual and homosexual mating preferences for age in men and women. Our study aimed to replicate these findings by examining age preferences in …
Non‐linear associations between stature and mate choice characteristics for American men and their spouses
OBJECTIVES: Although male height is positively associated with many aspects of mate quality, average height men attain higher reproductive success in US populations. We hypothesize that this is because the advantages associated with taller stature accrue mainly from not being short, rather than from being taller than average. Lower fertility by short men may be a consequence of their and their partner's lower scores on aspects of mate quality. Ta…
