Another health variable closely monitored around the world is obesity, reported in terms of adult prevalence rates, or the percentage of the population with a Body Mass Index (BMI) equal to or greater than 30.0 kg/m. Obesity rates can be used as proxies for overall health, food quality, and pre-disposition for other diseases such as diabetes and heart problems.

Excluding the West Bank, which hasn't reported this figure, how many of the remaining nations indicate obesity prevalences over 25% -- meaning over 1/4 of their total populations are considered obese and at risk for weight-related illnesses?

_____

How many have prevalences over 33% -- over 1/3 their total population?

_____

Answer choices:

1, 2, 3, 4, or 5

First things first: who has the most money? A nation's wealth can be measured in a variety of ways but the most common is via Gross Domestic Product, or GDP. There are actually several different ways of looking at GDP, so let's review some definitions before getting to the questions.

GDP Purchasing Power Parity (GDP PPP): Sum of all goods and services a nation possesses as valued by USA exchange rates. Calculating these can be difficult and tedious but they make for easy standardized global comparisons.

GDP Official Exchange Rate: Sum of all goods and services a nation possesses as valued by local currency and normalized via international exchange rates. This value is favored as a means to determine a nation's economic power in relation to its neighbors.

GDP Per Capita: Sum of all goods and services a nation possesses as valued by USA exchange rates (i.e., GDP PPP) divided by total population. This value allows economists to assess the economic status of individuals as opposed to the nation as a whole.

Now, back to our five comparison nations, answer the following questions:

Which of the five nations has the highest most recent Real GDP PPP?

Is it the same nation with the highest GDP Official Exchange Rate?

_____________________ Yes or No

Which nation has the wealthiest individuals (i.e., GDP Per Capita)?
