The issues of an ageing population in which the average age of a society is increasing is an important issue in many nations of the world. The societal effects of age are great. Young people tend to commit most crimes, they are more likely to push for political and social change, to develop and adopt new technologies, and to need education. Older people have different requirements from government as opposed to young people, and frequently differing values as well. Older people are also far more likely to vote and thus have comparatively more political influence. In demographics population ageing occurs when the average age of a regions population gets older. ...
Senescence: the biology of ageing
Main article: Senescence In biology, senescence is the state or process of aging. ...
In biology, senescence is the state or process of ageing. Cellular senescence is a phenomenon where isolated cells demonstrate a limited ability to divide in culture. Organismal senescence is the ageing of organisms. Main articles: Life All organisms (viruses not included) consist of cells, which in turn, are based on a common carbon-based biochemistry. ...
Organismal ageing is generally characterized by the declining ability to respond to stress, increasing homeostatic imbalance and increased risk of disease. Because of this, death is the ultimate consequence of ageing. Some researchers are treating ageing as a "disease" in gerontology (specifically biogerontologists), although this view is controversial. Stress (roughly the opposite of relaxation) is a medical term for a wide range of strong external stimuli, both physiological and psychological, which can cause a physiological response called the general adaptation syndrome, first described in 1936 by Hans Selye in the journal Nature. ...

Economics and marketing of ageing The economics of ageing are also of great import. Children and teenagers have little money of their own, but most of it is available for buying consumer goods. They also have considerable impact on how their parents spent their money.
Young adults are an even more valuable cohort. They often have jobs with few responsibilities such as a mortgage or children. They do not yet have set buying habits and are more open to new products.
The young are thus the central target of marketers. Television is programmed to attract the 15 to 35 years olds. Movies are also built around appealing to the young. For other uses see film (disambiguation) Film refers to the celluliod media on which movies are printed Film — also called movies, the cinema, the silver screen, moving pictures, photoplays, picture shows, flicks, or motion pictures, — is a field that encompasses motion pictures as an art form or as part of...
The middle aged and the old are less likely to buy things and are traditionally viewed as being set in their buying habits and not nearly as open to marketing. Older people tend to be much wealthier and to save a much higher percentage of their income.
Some tax systems attempt to address these differences in age spending habits such as the concept of a lifetime income tax. A lifetime income tax is an income tax that would tax a person based on their cumulative lifetime income, rather than their yearly income as is currently done throughout the world. ...
Global ageing trends There have been small changes in age distribution between 1990 and 2000. The percent of population that is older increased slightly between 1990 and 2000 from 9% to almost 10%. The increase was larger within more developed countries, from 17.7% to 19.4%. The percent of population that is older is almost three times as high in more developed countries (19.4%) as it is in less developed countries (7.7%).
