age structure

Title English: 
age structure
Definition English: 
The age structure of a population is the distribution of people among various ages. In graphic form, age structure is portrayed as an age pyramid whose relatively broad base indicates the number of children while the peak reflects the increasing likelihood of death as people age. A population whose age structure has a very broad base and a sharp narrow peak is said to be “young,” while a structure whose base is not much wider than the rest of the pyramid is “old.”
