so varying away from your list slightly, here's one i've made using information i've found :)
Newborn: 0months - 12 months
Toddler: 1 year - 3 years
Child: 4 years - 11 years
Youth: 12 years - 18 years
Adult: 18 years +
Elderly: 65 years +
A baby is usually classed as a newborn, where they can't really do a lot for themselves.
A tween usually refers to children between the ages of 9 and 13, basically the age where you're not a kid but you're not quite a teenager yet either.
A pre-teen, as far as i know, is within the 'tween' category, however it's more of a specific range. usually around 10-12 years of age.
An adolescent is usually from early teenager (13 years of age) to early adulthood (18 years of age)
A young adult is between the ages of 18 and 24, when you're still young and slightly immature, but well on your way to becoming an adult full time.
The grouping of an adult is often debated... some people say that you become and adult when you obtain adult-like duties and responsibilities. Basically when you start behaving like an adult. However you're usually classed as an adult from the age of either 18 or 21.
Elderly is usually based on the pension age, which is 65 :)
