Look up "sparse" and I think you'll understand the answer.
I still kinda don't get it.
What does sparsely populated mean?

Is it lots of people crowded together?
Or
Very few people in a large area?

Do people live near rivers and in flat areas?

Does East Asia have a lot of people or very few people?
