Replacement fertility, what has it been and what does it mean?

Replacement fertility is a term commonly used by demographers when referring to levels of childbearing and yet is rarely explained. It is normally presented as being around 2.1 children per woman. Continued below replacement fertility in developed countries and fertility falling in developing countries has given the concept of replacement fertility a higher profile. This article explains how replacement level is calculated and explores the concept further. Past replacement fertility levels are calculated for England and Wales. A possible alternative definition of replacement is also presented. Simple projection scenarios are used to show the effect on population of below replacement fertility, and also of postponement of fertility. The importance and implications of below replacement fertility are discussed.     

Have national trends in fertility between 1986 and 2006 occurred evenly across England and Wales?

During the past 20 years fertility patterns within England and Wales have changed considerably. The total fertility rate experienced a prolonged decline during the 1990s and hit a record low in 2001. Since then the level of fertility has increased fairly rapidly. Over the two decades, fertility has been constantly increasing at ages above 30, and as a consequence the mean age of motherhood has been rising. This article explores fertility trends within statistical regions and local authorities to improve our understanding of changes in fertility at the subnational level between 1986 and 2006.     

Football,Business, and Government—Can Studies of High-Level Teams Across Disciplines Produce Generic Principles for Systems and Management?

This paper describes work in progress which seeks to establish whether there are sufficient similarities between high-level teams operating in the business, government, and sporting environments to justify further research in these areas. It distinguishes strategic and tactical teams and identifies the characteristics of each within their separate disciplines. The paper concludes that there is indeed worthwhile research to be conducted in this field. Such research would not be confined to mere theory because the three areas investigated are already interconnected in a complex manner best investigated by a systemic approach.
