Mind-Blowing Fact of the Day: More Than Half the World’s Population Lives Inside This Circle

Some facts about this circle, which were observed by one “valeriepieris” on Reddit:

• This circle is mostly water.
• It contains the two most populous countries in the world, China and India.
• It also contains the most sparsely populated country in the world, Mongolia.
• There are more Muslims, Hindus and Buddhists inside it than outside it.

…and less relevant to the general discussion and more relevant to me: Yours Truly was born inside this circle.

There’s more about this circle on io9 and Reddit.
