As you might expect, populations with large percentages of young people (assuming the people are teenagers or older) will have a relatively high birth rate.  This is because people of that age are just entering their child-bearing years.  For example, your average 18 year old is likely to have more kids in the next 10 years than your average 40 year old.

A population with a lot of older people will of course have a higher death rate.  This is because, all other things being equal, old people are much more likely to die than young people.
