For the geography-challenged among you, Mongolia is here:
Sandwiched between giant Russia and China it looks pretty small, but Mongolia is actually the 19th largest country in the world, and it’s the 2nd largest landlocked country (after Kazakhstan there to the west).
In addition, Mongolia is the most sparsely populated independent country* in the world (with a population density of just 1.77 people/sq.km).
*There are a few places that have a lower population density than Mongolia, but they are dependent territories like Greenland (which is part of Denmark), and not independent nations.
(And yes, I know that was more than one fact. Deal with it.)
