A generation is the amount of time passed between births, or age difference between parents and their children, be it humans or animals. For studies and approximations regarding population growth, scientists use 30 years as the average human generation.

A generation is the time from birth to the time of parenting.
For hamsters, you can have a new generation every 90 days.
The ACCEPTED span of a generation for humans is appx 20 years.

its not really a measure of time, it represents a level of the tiers in a family tree. For instance you are a generation, you're children will be the next and their childeren the one after that. Since some people have kids in their teens and some have them as old as 50 there is no definitive answer.
