The move to later childbearing of recent decades has sparked a renewed interest in the measurement of time-trends in childbearing. Fertility measures that are adjusted for timing change have been proposed. The issue has been vigorously debated. Nà Bhrolcháin is an active contributor to this debate.
An empirical development of these ideas is being carried out within the ESRC Centre for Population Change. The work aims to address the process of delayed childbearing by describing how, in an accounting sense it has occurred. It seeks also to examine the potential causes of later and lower fertility in Britain, at the aggregate level, by applying the framework put forward by Nà Bhrolcháin and Dyson (2007).
