The generation into which each person is born, the demographic composition of that cohort, and its relation to those born at the same time in other places influences not only a person's life chances, but also the economic and political structures within which that life is lived; the person's access to social and natural resources (food, water, education, jobs, sexual partners); and even the length of that person's life. Demography, literally the study of people, addresses the size, distribution, composition, and density of populations, and considers the impact the drivers which mediate these will have on both individual lives and the changing structure of human populations

"Predicting the shape of our future populations is vital for installing the infrastructure, welfare, and provisions necessary for society to survive. There are many opportunities and challenges that will come with the changes in our populations over the 21st century. In this new addition to the 21st Century Challenges series, Sarah Harper works to dispel myths such as the fear of unstoppable global growth resulting in a population explosion, or that climate change will lead to the mass movement of environmental refugees; and instead considers the future shape of our populations in light of demographic trends in fertility, mortality, and migration, and their national and global impact. 'How Population Change Will Transform Our World' looks at population trends by region to highlight the key issues facing us in the coming decades, including the demographic inertia in Europe, demographic dividend in Asia, high fertility and mortality in Africa, the youth bulge in the Middle East, and the balancing act of migration in the Americas.

Demographic ageing is a reality - within 25 years half the population of Western Europe will be over 50, one quarter over 65, and the Less Developed Countries will contain one billion elderly people. Ageing Societies examines the myths, challenges and opportunities behind these figures. Ageing Societies explores three areas: the growing necessity for extending economic activity into later life and the implications of societal ageing for the intergenerational contract and the provision of social security the changes in modern families and the implications the changes have for the provision o

It appears likely that the twentieth-century approach of many aging European societies—relying on migrant workers from a younger, poorer South to prop up their economies—will no longer be a viable option in the coming decades.…
