Assessing the agreement between microsimulated and register-based kin counts in Sweden
Estimating kinship networks is a data-intensive undertaking, usually conducted using empirical sources or demographic models. Although empirical data, such as population registers, provide observed individual-level information, they are limited by availability, truncation, and survivorship bias. Demographic models, including microsimulation, require less detailed data, but they often minimally account for population heterogeneity, family similari…
Changing Landscapes of Parenthood: Childbearing Among Same‐Sex and Different‐Sex Couples in the Nordic Countries
The Nordic countries of Denmark, Sweden, Norway, and Finland were among the first countries to acknowledge same‐sex couples’ partnership and parenthood rights in their legislation. We explore trends over time in the share of female same‐sex and different‐sex couples that have children following their legal union and variation by socioeconomic status. Using harmonized register data, we assess couples’ likelihood of having a child over time, with a…
Attitudes towards childbearing, population, and the environment: Prevalence, correlates, and connections with fertility outcomes in Sweden
Environmental concerns may influence personal fertility decisions and general opinions about childbearing and population dynamics, but research on this topic remains scarce. In two analyses based on large Swedish datasets (the Gender and Generation Survey [GGS], N = 8027, and a survey designed for this project, N = 683), we examine the connection between climate change worry and fertility outcomes and compare the prevalence of various concerns, b…
Cohabitation and Mortality Across the Life Course: A Longitudinal Cohort Study with Swedish Register-Based Sibling Comparisons
Research has shown that married individuals live longer lives than unmarried women and men. A smaller number of studies have included non-marital cohabitation and have found that their mortality falls between the married and other unmarried groups. There are indications that the cohabiting population is diverse in terms of mortality risk, yet very little is known about how the association is related to age and stages of the life course. Sweden is…
The Demography of Sweden's Transgender Population: A Research Note on Patterns, Changes, and Sociodemographics
We examine the prevalence of gender transitions in Sweden over time and document the sociodemographic characteristics of people transitioning in different periods. Using administrative data covering the transgender population from 1973 through 2020, we analyze two common events in a gender transition: the earliest diagnosis of gender incongruence and the change of legal gender. Our research note presents three main findings. First, the measured p…
Universal Procreation Rights and Future Generations
It is often acknowledged that public policies can constrain people's procreative opportunities, in some cases even infringing their procreative rights. However, a topic that is not often discussed is how the procreative choices of one generation can affect the procreative opportunities of later generations. In this article, we argue that the demographic fact that childbearing above the replacement fertility level is eventually unsustainable suppo…
Socio-economic status is a social construct with heritable components and genetic consequences
Life expectancy by religious affiliation in Finland 1972-2020
Background: Religion and religiosity are known as important determinants of health and mortality. Previous studies on the interrelation between religion and mortality have relied on survey data or small cohort samples, and they have mainly been carried out in a North American setting. Objective: We provide a register-based study of life expectancy by religious affiliation for a total national population over the course of five decades. Methods: W…
Kinship, heritage, and ethnic choice: Ethnolinguistic registration across four generations in contemporary Finland
We studied how individuals' ethnolinguistic affiliation relates to the ethnolinguistic structure of kinship in contemporary Finland, a society in which Finnish-speaking and Swedish-speaking ethnolinguistic groups have coexisted for centuries and mixed marital unions are common. Using multigenerational data from the population register, we determined how the ethnolinguistic registration of children born in 1990-2015 relates to three generations of…
Religion and Fertility: A Longitudinal Register Study Examining Differences by Sex, Parity, Partner’s Religion, and Religious Conversion in Finland
We use longitudinal data on religious affiliation in Finland to examine childbearing behavior. All analyses are based on detailed fertility information from the Finnish national register of each person’s religious denomination for men and women born in 1956–1975. We identify higher fertility according to parity among members of the Evangelical Lutheran state church and other Protestant churches, and lower fertility among individuals with no relig…
Religion and mental health in young adulthood: A register-based study on differences by religious affiliation in sickness absence due to mental disorders in Finland
Epidemiologists and public health practitioners should further examine the association between mental disorders and church membership using administrative registers
Birth Spacing and Parents’ Physical and Mental Health: An Analysis Using Individual and Sibling Fixed Effects
An extensive literature has examined the relationship between birth spacing and subsequent health outcomes for parents, particularly for mothers. However, this research has drawn almost exclusively on observational research designs, and almost all studies have been limited to adjusting for observable factors that could confound the relationship between birth spacing and health outcomes. In this study, we use Norwegian register data to examine the…
Kinship and socio-economic status: Social gradients in frequencies of kin across the life course in Sweden
The influence of kin on various outcomes is heavily debated. However, kinship size itself conditions the probability of potential effects. Socio-economic gradients in the prevalence, variance, and types of kin are, therefore, a vital aspect of the functions of kin. Unfortunately, these parameters are largely unknown. We used Swedish register data to enumerate consanguine and in-law kin across the life course of the 1975 birth cohort. We calculate…
Socioeconomic Advantage or Community Attachment? A Register-Based Study on the Difference in National Lutheran Church Affiliation Between Finnish and Swedish Speakers in Finland
Secularization theory has been challenged by research showing religious persistence and upswing in contexts across the world. In Europe, particularly in highly secular and historically religiously homogeneous Nordic settings, there has been little research, and representative data for minority groups are rare. We offer a pioneering study using national register data to study religious changes over the past five decades in Finland, where the two n…
Parental union dissolution and the gender revolution
This study investigates two concurrent trends across Europe and North America: the increasing instability of parental unions and men's rising contributions to household work. Because children have almost universally resided with their mothers and it is difficult for non-residential fathers to maintain any levels of care work, union dissolutions have potentially slowed societal increases in gender equality. A new family form-50/50 living arrangeme…
The Inequality of Lifetime Pensions
At older ages, most people are supported by pension systems that provide payments based on prior contributions. An important, but neglected, aspect of inequality in how much people receive in pensions is the number of years they live to receive their pension. We examine inequality in lifetime-accumulated pensions and show the importance of mortality for understanding inequalities in pension payments, and contrast it to inequalities in working-age…
The Swedish Kinship Universe: A Demographic Account of the Number of Children, Parents, Siblings, Grandchildren, Grandparents, Aunts/Uncles, Nieces/Nephews, and Cousins Using National Population Regis…
Given that surprisingly little is known about the demography of human kinship, we provide a demographic account of the kinship networks of individuals in Sweden in 2017 across sex and cohort between ages 0 and 102. We used administrative register data of the full population of Sweden to provide the first kinship enumeration for a complete population based on empirical data. We created ego-focused kinship networks of children, parents, siblings, g…
The relationship between life-course accumulated income and childbearing of Swedish men and women born 1940-70
This study uses income accumulated over ages 20-60 to examine whether richer or poorer individuals have more children. Income histories are calculated using yearly administrative register data from contemporary Sweden for cohorts born 1940-70. Differences by parity and income distribution are examined separately by sex. There is a strong positive gradient between accumulated disposable income (and to a lesser extent earnings) and fertility for me…
Divorce among exogamous couples: The role of language convergence
This is the first study to use longitudinal population register data to illustrate that marital stability may relate to the adoption of the spouse's language. The paper draws on theories of boundary shifting and boundary crossing to examine two main ancestral groups in Finland, Finnish speakers and Swedish speakers, between whom intermarriage is common. Administrative changes in how the question about language/ethnicity was registered between the…
The Shadow of Peasant Past: Seven Generations of Inequality Persistence in Northern Sweden
The authors use administrative data linked to parish records from northern Sweden to study how persistent inequality is across multiple generations in education, occupation, and wealth, going from historical to contemporary time. The data cover seven generations and allow the authors to follow ancestors of individuals living in Sweden around the new millennium back more than 200 years, covering the mid-18th century to the 21st century. In a sampl…
Demographic Theory and Population Ethics
Demographic theory is concerned with how population systems regulate themselves given available resources and external shocks to population size. This chapter provides an overview of demographic theory, focusing specifically on relationships between population size, population growth, and welfare. It then discusses four implications of demographic theory for population ethics. Speaking broadly, these four implications concern (1) the overreliance…
Sibling similarity in income: A life course perspective
Sibling similarity in income is a measure of the omnibus effect of family and community background on income. We estimate sibling similarity in income accumulated over the life course (ages 18 to 60) to demonstrate that previous research has underestimated sibling similarity in income. Using high-quality Swedish register data, we find sibling similarity in accumulated, lifetime income to be much higher than sibling similarity in income measured o…
Sex Selection for Daughters: Demographic Consequences of Female-Biased Sex Ratios
Modern fertility techniques allow parents to carry out preimplantation sex selection. Sex selection for non-medical purposes is legal in many high-income countries, and social norms toward assisted reproductive technology are increasingly permissive and may plausibly become increasingly prevalent in the near future. We explore possible outcomes of widely observed daughter preferences in many high-income countries and explore the demographic conse…
How Does Mortality Contribute to Lifetime Pension Inequality? Evidence From Five Decades of Swedish Taxation Data
As with many social transfer schemes, pension systems around the world are often progressive: individuals with lower incomes receive a higher percentage of their income as a subsequent pension. On the other hand, those with lower earnings have higher mortality and thus accumulate fewer years of pension income. Both of these opposing factors influence the progressiveness of pension systems. Empirical efforts to disentangle the effects of mortality…
Government Transfers to Parents and Population Policy in a Global Perspective: An Economic Demographic Perspective
The world is rapidly converging towards lower fertility: in 2020, countries with a total fertility rate of less than 2.25 will encompass more than three-quarters of the world population. This implies that the determinants of childbearing will be increasingly similar in high-income and middle-income regions of the world. In this article, I discuss economic demography in relation to levels of childbearing. How do different societies distribute reso…
Beyond the Economic Gaze: Childbearing During and After Recessions in the Nordic Countries
During the 2010s, fertility rates fell across the Nordic region. The onset of these declines seems linked to the Great Recession of 2008–2009, but their continuation cannot easily be linked to subsequent economic change. The 1990s, too, brought episodes of economic crises to the Nordic region that were followed by different degrees of fertility decline. In this study, we provide an empirical overview of parity-, age- and education-specific fertil…
Understanding transmission of fertility across multiple generations – Socialization or socioeconomics
A Life-Course Analysis of Geographical Distance to Siblings, Parents, and Grandparents in Sweden: A Life-Course Analysis of Geographical Distance to Kin
This study makes a contribution to the demography and geography of kinship by studying how internal migration and demography shape the geographical availability of kin in contemporary Sweden. Age structures an individual's relationship with their parents and other kin, and this is reflected in how geographical distance to kin varies over the life course. This study uses a longitudinal approach in which the distance to siblings, parents, and grand…
Two Decades of Same-Sex Marriage in Sweden: A Demographic Account of Developments in Marriage, Childbearing, and Divorce
In this study, we provide demographic insight into the still relatively new family form of same-sex marriage. We focus on period trends in same-sex marriage formation and divorce during 1995–2012 in Sweden and the role of childbearing in same-sex unions. The period begins with the introduction of registered partnership for same-sex couples and also covers the introduction of formal same-sex marriage in 2009. We use register data for the complete …
Reproductive history and post-reproductive mortality: A sibling comparison analysis using Swedish register data
A growing body of evidence suggests that reproductive history influences post-reproductive mortality. A potential explanation for this association is confounding by socioeconomic status in the family of origin, as socioeconomic status is related to both fertility behaviours and to long-term health. We examine the relationship between age at first birth, completed parity, and post-reproductive mortality and address the potential confounding role o…
Age Differences in Unions: Continuity and Divergence Among Swedish Couples Between 1932 and 2007
Multigenerational transmission of family size in contemporary Sweden
The study of the intergenerational transmission of fertility has a long history in demography, but until now research has focused primarily on parents' influence on their children's fertility patterns and has largely overlooked the possible influence of other kin. This study examines the transmission of fertility patterns from parents, grandparents, uncles, and aunts, using event history models to determine the risk of first, second, and third bi…
Educational Expansion and Intergenerational Proximity in Sweden
Education is one of the most important drivers of regional migration in European countries, and educational expansion has been a major social phenomenon in the last decades. We use decomposition analysis to examine how the expansion of tertiary education has affected intergenerational distance between adult children and their parents in Sweden. We use administrative register data for the complete population of Sweden and examine changes in interg…
When and Where Birth Spacing Matters for Child Survival: An International Comparison Using the DHS
A large body of research has found an association between short birth intervals and the risk of infant mortality in developing countries, but recent work on other perinatal outcomes from highly developed countries has called these claims into question, arguing that previous studies have failed to adequately control for unobserved heterogeneity. Our study addresses this issue by estimating within-family models on a sample of 4.5 million births fro…
The Influence of Health in Early Adulthood on Male Fertility
Despite the large literature examining predictors of fertility, previous research has not offered a population-level perspective on how health in early adulthood is related to male fertility. Using Swedish population and military conscription registers, we study how body mass index (BMI), physical fitness, and height are associated with total fertility and parity transitions by 2012 among 405,427 Swedish men born 1965-1972, meaning we observe fer…
Birth Order and Mortality: A Population-Based Cohort Study
This study uses Swedish population register data to investigate the relationship between birth order and mortality at ages 30 to 69 for Swedish cohorts born between 1938 and 1960, using a within-family comparison. The main analyses are conducted with discrete-time survival analysis using a within-family comparison, and the estimates are adjusted for age, mother’s age at the time of birth, and cohort. Focusing on sibships ranging in size from two …
Deliberate Birth Spacing in Nineteenth Century Northern Sweden
The relationship between life-course accumulated income and childbearing of Swedish men and women born 1940-70
This study uses income accumulated over ages 20-60 to examine whether richer or poorer individuals have more children. Income histories are calculated using yearly administrative register data from contemporary Sweden for cohorts born 1940-70. Differences by parity and income distribution are examined separately by sex.

The causal effect of an additional sibling on completed fertility: An estimation of intergenerational fertility correlations by looking at siblings of twins
Intergenerational transmission of fertility - a correlation between number of siblings and adult fertility - has been consistently demonstrated in developed countries. However, there is only limited knowledge of the causes of this correlation
The Long-Term Cognitive and Socioeconomic Consequences of Birth Intervals: A Within-Family Sibling Comparison Using Swedish Register Data
We examine the relationship between birth-to-birth intervals and a variety of mid- and long-term cognitive and socioeconomic outcomes, including high school GPA, cognitive ability, educational attainment, earnings, unemployment status, and receiving government welfare support. Using contemporary Swedish population register data and a within-family sibling comparison design, we find that neither the birth interval preceding the index person nor th…
The effect of number of siblings on adult mortality: Evidence from Swedish registers for cohorts born between 1938 and 1972
Demographic research has paid much attention to the impact of childhood conditions on adult mortality. We focus on one of the key aspects of early life conditions, sibling group size, and examine the causal effect of growing up in a large family on mortality. While previous studies have focused on low- or middle-income countries, we examine whether growing up in a large family is a disadvantage in Sweden, a context where most parents have adequat…
Weak support for a U-shaped pattern between societal gender equality and fertility when comparing societies across time
A number of recent theories in demography suggest a U-shaped relationship between gender equality and fertility. Fertility is theorized to be high in societies with low levels of gender equality, as well as in societies with high gender equality, with lowe
Women's Experience of Child Death Over the Life Course: A Global Demographic Perspective
The death of a child affects the well-being of parents and families worldwide, but little is known about the scale of this phenomenon. Using a novel methodology from formal demography applied to data from the 2019 Revision of the United Nations World Population Prospects, we provide the first global overview of parental bereavement, its magnitude, prevalence, and distribution over age for the 1950–2000 annual birth cohorts of women. We project th…

How Does Birth Order and Number of Siblings Affect Fertility? A Within-Family Comparison Using Swedish Register Data
This study examines how the sibling constellation in childhood is associated with later fertility behaviour of men and women in Sweden. Administrative register data are used to investigate how birth order affects completed fertility, how the number of siblings and birth order jointly affect completed fertility, and in both cases if there are gender differences in these relationships. Our data consist of all fully biologically related siblings in …
Mesures des migrations internes par période et par cohorte
La migration est rarement analysée selon une perspective de cohorte, ce qui n'est pas le cas pour la fécondité et la mortalité. Cette étude montre comment utiliser une méthodologie démographique standard pour étudier la migration interne en associant période et cohorte au niveau de la population. Les taux de migration par âge et le taux de migration totale sont présentés pour les données de période et de cohorte. Les données du registre administr…

Parental Status and Gender Preferences for Children: Is Differential Fertility Stopping Consistent With the Trivers–willard Hypothesis?
Based on evolutionary reasoning, Trivers & Willard (1973) predicted status-biased sex composition and parental investment with son-preferencing effects in higher, and daughter-preferencing effects in lower status groups. Previous research shows mixed results. This study uses event-history methods and Swedish register data to study one possible mechanism in isolation: do parents in different status groups vary in their proclivities to continue fer…

Socioeconomic status and sex ratios at birth in Sweden: No evidence for a Trivers–Willard effect for a wide range of status indicators
OBJECTIVES: This study examines if there exists a positive association between socioeconomic status and the proportion of male births in humans, as proposed by Trivers and Willard in 1973, using individual-level data drawn from the complete population of Sweden. METHODS: We examine more than 3,000,000 births between 1960 and 2007 using administrative register data with comprehensive information on various dimensions of socioeconomic status. We us…

Explaining Swedish sibling similarity in fertility: Parental fertility behavior vs. social background
The aim of this descriptive study is to determine which of the family-specific factors, parental fertility behavior or social background, matters most for the intergenerational transmission of fertility
Uxorilocal marriage as a strategy for heirship in a patrilineal society: Evidence from household registers in early 20th-century Taiwan
In pre-industrial Taiwan, an uxorilocal marriage, in which a man moved in with his bride’s family, was a familial strategy used to continue family lineage and to enhance family farm labor. We examine the prevalence and circumstances in which a family would call in a man for one of their unmarried daughters. Using data from the Taiwan Historical Household Registers Database (THHRD) from 1906–1945, we identify the individual-level factors (includin…
Parity and Mortality: An Examination of Different Explanatory Mechanisms Using Data on Biological and Adoptive Parents
A growing literature has demonstrated a relationship between parity and mortality, but the explanation for that relationship remains unclear. This study aims to pick apart physiological and social explanations for the parity-mortality relationship by examining the mortality of parents who adopt children, but who have no biological children, in comparison with the mortality of parents with biological children. Using Swedish register data, we study…

A population-based cohort study of socio-demographic risk factors for Covid-19 deaths in Sweden
As global deaths from COVID-19 continue to rise, the world’s governments, institutions, and agencies are still working toward an understanding of who is most at risk of death. In this study, data on all recorded COVID-19 deaths in Sweden up to May 7, 2020 are linked to high-quality and accurate individual-level background data from administrative registers of the total population. By means of individual-level survival analysis we demonstrate that…
