The reasons why life expectancy, young and old and dependency load comparisons exist and also what they're used for.

# data[].attributes.body
They all exist so that we have a constant understanding of the population situations that countries are in. It also helps Governments, Health facilities and Statistics holders like Statistics Canada.

They can also show us which countries are in need of supplies or just need help in general.

Why should we care about the ageing population? Why should we care about birth rates, life expectancy and dependency loads?

# data[].attributes.body
We should care because this will eventually affect ALL of us at one point or another in the future, not only that but it is something that we should also care about now. Due to the amount of older people we are seeing a decline in the working population and seeing more dependent people throughout the world, that is why we should care.
