Answer

Birth Rates

There is a high birth rate of both males and females in developing countries. A large proportion of children indicates a rapidly growing population. In contrast, developed countries have a low or declining birth rate due to increased knowledge of family planning.

Death Rates

Death rates are lower in developed countries. More people survive to old age, which is represented by the wider peak of the pyramid. This difference is largely due to better access to medical care.

Life Expectancy

People in developed countries enjoy a longer life expectancy than those in developing countries. This stark difference is attributed to the availability of resources such as food, balanced diets, clean water, and overall better standards of medical care, sanitation, and child mortality rates.
