For at least UK in 1918, the compulsory education upper age limit is 14. I was always wonder at that age in the late 19th century/early 20th century, what do the kids work as when they finish their schooling, especially for the urban working class?

I assume the list of jobs the kids have after their school would be limited, like mostly blue collar work. For the girls, I think they are mostly confined to housework since their choices are limited back in the day.

What do you guys think the answer is? Is my guesses right or wrong?
