Tends to be associated with those between 12 and 25
In our culture, it is socially constructed (e.g. 50's saw the emergence of youth culture based on fashion and hairstyles, spending power in the 50s meant there was a new market in targeting young people)
Old age and childhood are socially constructed in similar ways (e.g. society suggests them to infantilisation, the elderly live in care homes since they're labelled as 'dependent', which takes away all aspects of their identity by controlling their lives)
The stages of life are based on the relationships around family, work and the economy
In a postmodern world, things are changing and fragmenting (e.g. fertility treatment means having children later, age for having children is no longer a milestone, music and fashion are less associated with certain generations because of streaming and easy access)
Media's image of ageing can lead to positive and negative stereotypes
It can also create new identities because when the population ages, more positive images can emerge (e.g. the popularity of retro fashion and sampling music from 60's bands, show that trends help dissolve the boundaries of age)
Many media role models who are successful and attractive in older years are prevalent in today's society (e.g. the rolling stones, Madonna and Mariah Carey)
Perspectives on how age identities are not changing
Interactionists (labelling of the elderly, self fulfilling prophecy, infantilisation)
Marxists (the elderly are used as a reserve army of labour, with young and old)
Media (representation of age groups still differ, for example young people are still seen as deviant, through explanations such as moral panics, and old people are still seen as grumpy and senile)
