Older people have different requirements from society and government, and frequently have differing values as well, such as for property and pension rights. [1] Older people are also more likely to vote, and in many countries the young are forbidden from voting. Thus, the aged have comparatively more, or at least different, political influence. [2]
Adult development encompasses the changes that occur in biological and psychological domains of human life from the end of adolescence until the end of one's life. Changes occur at the cellular level and are partially explained by biological theories of adult development and aging. [1]

In Western societies, for example, both the old and the young are perceived and treated as relatively incompetent and excluded from much social life.
Population ageing is a shift in the distribution of a country's population towards older ages and is usually reflected in an increase in the population's mean and median ages, a decline in the proportion of the population composed of children, and a rise in the proportion of the population composed of the elderly.

Social gerontologists are responsible for educating, researching, and advancing the broader causes of older people. [29] Because issues of life span and life extension need numbers to quantify them, there is an overlap with demography. Those who study the demography of the human life span differ from those who study the social demographics of ...
Normally, developing societies have lower life expectancies in comparison to developed countries. They have also found correlations between mortality and sex and age. Very young and old people are more susceptible to sickness and death. On average women typically live longer than men, although women are more likely to have bad health. [17]
