Pronunciation

Noun

generations

1. Plural of generation.

Generation (from the Greek γενεά), also known as procreation, is the act of producing offspring. 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 evolution.

Length

A generation has traditionally been defined as “the average interval of time between the birth of parents and the birth of their offspring." This places a generation at around 20 years in span and this matches the generations up to and including the Baby Boomers. However, while in the past this has served sociologists well in analysing generations, it is irrelevant today.

Firstly, because cohorts are changing so quickly in response to new technologies, changing career and study options, and because of shifting societal values, two decades is far. Secondly, the time between birth of parents and birth of offspring has stretched out from two decades to more than three. Looking at Australian statistics, the median age of a woman having her first baby was 24 in 1976, while today it is just over 30.

So, today a generation refers to a cohort of people born into and shaped by a particular span of time (events, trends and developments). And the span of time has contracted significantly.

Generational labels

The various labels given the living generations – the Builders through to Gen Z – reflect the times which have shaped their generational profile. The names given the Builders reflect the events that shaped them (the World Wars and the Depression); the Boomer labels, the population boom following World War II and the shedding of moral codes after the sexual revolution of the 60s and 70s (the love generation and the lost generation, for example); the X-er labels, the material prosperity of the times (the options generation) and the after-math of the sexual revolution (the baby-busters), and the Gen Y labels, the digital age that heralded in its birth.

Generation Table

Please note that these years that have been noted are quite vague and may differ slightly (in some cases quite substantially) from country to country.
