angola has the highest dependency load.

Dependency Load:

the reason that these countries have these patterns is that Angola has a healthy population where the amount of 0-14 population is more than the population of 65+. but the other two countries have an old population which means the amount of 65+ population is more than the population of

0-14 children.

Birth rate:

Why do some countries have a high birth rate and some countries have a low birth rate?

it all depends on the economy of that country and the amount of people that live in that country and their financial situation.

Life expectancy:

Why do some countries have a high life expectancy and some countries have a low life expectancy?

life expectancy depends on the amount of support, health care, medicines, and the environment. that could result in making a country have a higher life expectancy.

the reason that we care about this subject is that we need to know about our population and if there is a problem in our population (ex: decreasing population or having old population) so we can fix that problem. with fixing this problem we could help our populations and help our environment.

birth rate: the number of live births per thousand of the population per year.

life expectancy: Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age.

total dependency: the total of the number of the population that can change the number of the whole population (0-14 and 65+)
