Congo

 

Right now the congo is in the extremely rapid growth pyramid range. there are way to many yooung people and only a few middle aged people and there are close to none when it comes to seniors. Because the congo has such a low life expectancy all of the people die at a very young age, so there isnt a lot of middle aged people and the ones that are still alive have a TON of kids because the IMR is so high. then when the parents die the kids have to go out and fend for themselves. As far as we can tell from recent population pyramids the congo is in very big trouble unless they live linger and have less children.
