This cool map from Facebook's Stories site plots Facebook friendships that span international borders-- something that might tell us a bit about the relationships between those countries. Most of them are pretty straightforward, but there are a few bonds that might surprise you:
Who knew that Ukraine and Nigeria could be so closely linked? (international students)
What about Indonesia and the Central African Republic? (hint: migrant labor)
The Philippines and Saudi Arabia? (also labor)
Spain and Romania? (you guessed it- labor again)
Somalia and Sweden? (refugees)
