Welcoming Contraception Failure? Towards a Flexible Model of Reproductive Decision-Making

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”.

A functional data analysis approach for forecasting age-specific population size: A case study for the United Kingdom

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 […]

Notes on the relationship between education and fertility among men

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 […]
