Long-term Dynamics of Household Size and Environmental Implications
Little is known about the environmental implications of long-term historical trends in household size. Now researchers Mason Bradbury, M. Nils Peterson and Jianguo Liu recently presented the first historical assessment of global shifts in average household size based on a variety of datasets covering the period 1600–2000.

Their findings reveal that developed nations reached a threshold in 1893 when average household size began to drop rapidly from approximately 5.0 to 2.5. A similar threshold was reached in developing nations in 1987. With the notable exceptions of Ireland, and England and Wales in the early 1800s, and India and the Seychelles in the late 1900s, the number of households grew faster than population size in every country and every time period.

These findings suggest accommodating housing may continue to pose one of the greatest environmental challenges of the twenty-first century because the impacts of increased housing present a threat to sustainability even when population growth slows.

Population Europe's Interactive Exhibition to be Shown in the UK
What are your chances of living to 100? How do your early years, your family life, where you live, your lifestyle and your work affect these chances? With one in three children born in 2012 expected to live to 100, these questions have never been more important. In collaboration with the ESRC Centre for Population Change (CPC) Population Europe's interactive exhibition "How to get to 100 - and enjoy it" will be shown to the UK in autumn/winter 2014, designed to unravel the challenges and opportunities associated with demographic research.

Who opts for self-employment after retirement? A longitudinal study in the Netherlands

Who opts for self-employment after retirement? A longitudinal study in the Netherlands
Self-employment among older age groups is rising. A new study by Hanna van Solinge tries to provide a better understanding of the role of self-employment and the extension of working lives of individuals.

Hanna van Solinge examines the factors associated with entry into self-employment post-retirement, after a worker has left a regular salaried position.

Data were derived from the Netherlands Interdisciplinary Demographic Institute Work and Retirement Panel, an ongoing longitudinal survey of older workers (50 years and over) employed by three private sector organisations and employed as civil servants in the Netherlands.

The results of this study show that the decision to pursue self-employment is primarily taken by retirees with relatively high levels of financial and human capital (wealth and educational attainment), those possessing entrepreneurial attitudes (high self-efficacy scores) and those who perceive their retirements to be completely involuntary.

Smoking and Physical Inactivity - a 39-Year Prospective Study

Smoking and Physical Inactivity - a 39-Year Prospective Study
Non-smokers and physically active people are said to live a longer and healthier life. But what about the other ones? Researchers Benjamin A. Shaw and Neda Agahi used data from a national sample of Swedish adults, originally interviewed in 1968 and followed until 2007 to estimate the long-term mortality hazards and disability risks associated with various combinations of smoking and physical inactivity.

Their results suggest that mortality rates were elevated among persistent and new smokers, but not among discontinued smokers. However, mortality rates remained elevated among discontinued smokers who were also persistently inactive.

As such, these findings indicate that while persistent smoking during midlife primarily impacts subsequent mortality, persistent physical inactivity during midlife appears to counteract the survival benefits of smoking cessation, while also imposing a long-term risk on late life disability among those who do survive to old age.
