If unemployment is high in your country what do most of you do for a living (besides leave the country) and why do many of you still have a lot of kids?

I'm not from Nigeria nor do I know anyone from there so I apologize if this post comes across as ignorant and uninformed but I'm confused. I see posts saying unemployment is high in the country if that's the case what do most of you do to survive (the one's that can't leave the country anyway) Like is Armed robbery rampant over there? Also if unemployment is high why do so many people there have kids like I know education and access to birth control is pretty bad but do the parents not think about what's gonna happen to their kids and how do they feed them if they themselves have no job? I'm just a little confused about the whole thing.
