North Korea frequently makes headlines as its government continues to tout its military hardware and make boisterous, but so far benign, nuclear threats.
The country has also been linked to several cyber-related incidents lately, but it denies involvement.
Still, the one thing that remains a bit of a mystery is what goes on inside the hermit kingdom, as data isn't readily available or reliable. But check out below some of the things we do know about what makes the country tick:

The CIA says literate people are those age 15 and over who can read and write.
