Population age composition is recognized as determining numerous aspects of society – from fertility rates to pension policies. One type of population age structure, a youth bulge, has its own particular effects. A youth bulge generally refers to a population with a high proportion of 15-24 year olds. A positive effect of a youth bulge […]
Giorgi Kankia and Lika Zhvania write about population change in the country of Georgia from a spatial development perspective. Shrinking population The population of Georgia is shrinking. According to official statistics, it decreased by 1.2 mln (nearly 25% of the total population in 1990) in 1994 – 2018. Somewhat decreased fertility rates or armed conflicts […]
Lea Taragin-Zeller discusses the lived experience of contraceptive choice and childbearing. Today, we have come used to thinking of every child as either “planned” or “unplanned”. Children are either a calculated choice of rational parents or a “mistake” made by irresponsible parents. But, while I was conducting research among Israel’s Orthodox Jews, I realised that […]
Jon Minton introduces the Shiny app he developed for exploring mortality based on the Human Mortality Database.
Katrin Schwanitz writes about cross-national variation in transition to adulthood.
Over 50 million Hispanics live in the United States. One-quarter speak English and no other language, and another 40% speak English very well. The other 18 million Hispanics are split between those who speak English well (38%), not well (37%), and not at all (26%). Remarkably, we know little about where Hispanics with divergent English […]
Xiana Bueno and Mary Brinton write about the gap between fertility ideals and intentions in Sweden, Japan, United States and Spain.
Retreating from conferences Picture it. You’ve been working on your presentation for a big conference for months. Last night, insomnia took hold and you were running through your slides in a sweat. You’re there, ready to present, and you look around the room and you see a sparse sea of faces, most of whom look […]
Frans Willekens discusses multi-staged decision processes over the human life course. His post is based on the Population Studies special issue dedicated to the subject published in October 2017. 1.The importance of individual agency for demography Population change is determined by the life choices individuals and families make. To understand population change, we need to understand […]
Han Lin Shang writes about forecasting age-specific population size based on an example of the UK. In recent decades, we have seen a considerable amount of development in the stochastic modelling and forecasting of population. Cohort component projection models are often used to model the evolution of age-specific population, and are particularly useful to highlight which […]
The study of the family has had a long and distinguished history in the demographic research tradition. A central preoccupation of this early work was the development of methods to obtain information about family structures from basic demographic characteristics of populations. As a result of this work, we learned to adapt classic life table methods […]
Jessica Nisén writes about educational differences in fertility among men. Interest and literature on fertility patterns of men is on the increase among demographers. While educational differences in women’s fertility have been well documented, there is less corresponding research on men. The long-standing finding that women educated to higher levels often end up childless and […]
Nikkil Sudharsanan writes about the size and drivers of adult life expectancy disparities between socio-economic strata in Indonesia. For over 40 years, researchers have found that high socioeconomic status (SES) individuals in high-income countries live longer than individuals with low SES. Although these findings have existed for decades, interest in mortality inequality has surged in […]
Valeria Cetorelli writes about results of a new survey that estimates the extent of ISIS violence against Yazidis in Iraq. During the summer of 2014, ISIS subjugated the Nineveh governorate in northern Iraq, home to most of Iraq’s minority groups. These minorities were systematically targeted by ISIS in a violent campaign to ‘purify’ the region […]
In this post, Ilya Kashnitsky shows how we can use freely available data and statistical software to create a consistent demographic time series. NUTS stands for the Nomenclature of Territorial Units For Statistics. The history of NUTS dates back to the beginning of 1970s, when European countries developed unified standards for systems of administrative geography. It was […]
Shangjie Lai writes about the role of migration in transmission routes of malaria between sub-Saharan Africa and China. The international spread of infectious diseases including Plasmodium falciparum malaria has been accelerated by increasing human mobility via air travel over recent decades. An emerging route of P. falciparum infection is from Africa to China by Chinese […]
Roselinde van der Wiel writes about commitment in ‘living-apart-together’ (LAT) relationships and the factors underlying this commitment. In the past decades, new relationship types have arisen that suggest that commitment is of less importance in modern, individualized societies. ‘Living apart together’ (LAT) is one such relationship type. LAT refers to longer-term, monogamous partners who consider […]
The global population is ageing and many experts predict that this will have some negative consequences for society. But in new research, we examine whether the demographic transition also has important positive consequences, including the promotion and development of democracy. In 1970, only 8 per cent of the world’s population was classified as ‘old’ (aged […]
Katharina Wolf writes about gendered authorship in demographic publication. Attaining gender equality is one of the major challenges of today’s societies. In most Western countries women have reached parity or even outperformed men in terms of higher educational attainment. This development has been accompanied by women’s greater involvement in academic research output, which is one […]
