Exercise 4

Refer to the population pyramids generated in the previous problem for Afghanistan and the United States. How does the age distribution compare between these two populations?

Step 1 of 2

The age or population pyramid is used by demographers from many years as well as epidemiologists for tracking as well as comparing the changes inside the age of population distribution over time.

Larger as well as smaller cohorts of the people that were born at the same year that could be seen for moving up of the life span as well as population pyramid from over time. The count of people from various ages within a population is selected like changes in time, state, levels of fertility, mortality rates as well as migration.

Thus, it can be said that the population changes with time as well as it is dynamic. The gender traits as well as age traits at a distinct point are collected generally at the point of decimal census.
