I believe it's birth rates r high because if it's it's narrow at the top it's high death and if it's wide at bottom it's high birth rates if I'm wrong I'm sorry
A population pyramid with wide base and tapered at top shows that the number of young people in a given population are higher than people of other age group. This usually happens when the birth rate is high. This kind of population pyramid can be seen for countries with lower rate of development or are under developed. For example – Nigeria, Mexico, Bangladesh have such population pyramids
