When it comes to companies, it can be hard to get a feel for their size. They may say they're "big," but what does that actually mean? Consider Walmart, for example.
This year, for the seventh time in the past decade, Fortune magazine awarded the retailer the No. 1 slot on it's annual list of the 500 largest American companies, as measured by revenues.
Fortune reports that 2.1 million people work at Walmart, which means there are about as many Walmart employees sprinkled across the globe as there are people living in the African country of Namibia.
If Walmart and it's employees were a country they would be, population-wise, bigger than 95 actual countries and hold the 25th largest economy in the world.
