How great is America really? A global election report card

Donald Trump has promised to "make America great again."

Hillary Clinton thinks it's already an "exceptional nation."

How does the US measure up to the rest of the world on key issues that are important to voters? Here's what we found:

ECONOMY

The economy is the top issue for voters, according to a July survey from the Pew Research Center. But if high unemployment rates were an issue during the 2008 and 2012 races (6.1% and 7.8%), that isn't the case this year.

America's jobless rate is hovering around 4.9%. It's the tenth best among countries in the Organization for Economic Cooperation and Development (OECD) -- a group that includes the world's richest nations.

But if the jobless rate is declining, income inequality is on the rise.

HEALTH CARE

Health care is a key issue for many voters, and that's no surprise -- the US spends more on health care per person than any other high-income country in the world.

On average, Americans dish out $1,810 more per head than the next highest spenders in Luxembourg, twice as much as Canadians, and almost nine times more than Mexicans, according to our calculations based on OECD data.

However, the extra money doesn't deliver better health-related outcomes. Studies have shown that Americans have a shorter life expectancy and higher prevalence of chronic illnesses than citizens of most other wealthy nations.

An estimated 310 million guns are owned by American civilians, according to the US Department of Justice, while the US Census Bureau estimates the current population of the US at 324 million people.
