Health inequalities can be referred to as the unjust and unavoidable differences across the population.
One example of this is maternal mortality. The reason being is that it shows a gap between different areas in the world as developing countries account for 99% of annual maternal mortality.
Another good example of this is premature death. The reason for this is that 87% of noncommunicable diseases tend to occur in low and middle income countries.
Gross domestic product can tell you how wealthy a country is and when you compare the US to those who are similar they seem to not compare as well as the others.
But when you look at other countries and compare their GDP it doesn't quite compare to the US as the others seem to fail to keep up with the US.
After learning about this section it came as a surprise to me that even with the US atop of a lot of countries they still lack the ability to help those of lesser to be able to sustain a healthy lifestyle.
