An age-based subgroup consisting of people in adjacent birth cohorts, in which most members have shared a similar sociohistorical event in a similar manner (e.g. the baby boom generation). This event often influences life chances and life styles throughout the life cycle. Different generations may experience different processes of socialization, which may result in conflict due to what has been called the generation gap.

Quotes:

"The longer I live the more keenly I feel that whatever was good enough for our fathers is not good enough for us." - Oscar Wilde

"A man's liberal and conservative phases seem to follow each other in a succession of waves from the time he is born. Children are radicals. Youths are conservatives, with a dash of criminal negligence. Men in their prime are liberals (as long as their digestion keeps pace with their intellect). The middle aged run to shelter: they insure their life, draft a will, accumulate mementos and occasional tables, and hope for security. And then comes old age, which repeats childhood -- a time full of humors and sadness, but often full of courage and even prophecy." - Elwyn Brooks White

"It is fortunate that each generation does not comprehend its own ignorance. We are thus enabled to call our ancestors barbarous." - Charles Dudley Warner

"I avoid talking before the youth of the age as I would dancing before them: for if one's tongue don't move in the steps of the day, and thinks to please by its old graces, it is only an object of ridicule." - Horace Walpole

"Eighteen might look at thirty-four through a rising mist of adolescence; but twenty-two would see thirty-eight with discerning clarity." - Source Unknown

"I suppose you think that persons who are as old as your father and myself are always thinking about very grave things, but I know that we are meditating the same old themes that we did when we were ten years old, only we go more gravely about it." - Henry David Thoreau

An infant, his mother, his maternal grandmother, and his great-grandmother. Thus there are four generations of one family in this photograph.

Generation (from the Greek γενεά), also known as procreation, is the act of producing offspring. In a more generic sense, it can also refer to the act of creating something inanimate such as electrical generation or cryptographic code generation.

A generation can also be a stage or degree in a succession of natural descent as a grandfather, a father, and the father's son comprise three generations. A generation can refer to stages of successive improvement in the development of a technology such as the internal combustion engine, or successive iterations of products with planned obsolescence, such as video game consoles or mobile phones.

In biology, the process by which populations of organisms pass on advantageous traits from generation to generation is known as evolution.

Familial generation

It is important to distinguish between familial and cultural generations. A familial generation is defined as the average time between a mother's first offspring and her daughter's first offspring. The generation length is 25.2 years in the United States as of 2007[1] and 27.4 years in the United Kingdom as of 2004[2].

Cultural generation

A cultural generation refers to the cohort of people whose youth was shaped by a particular set of events and trends. 20th-century cultural generations are shorter than familial generations.
