Bank of America Merrill Lynch is out with its "Transforming World Atlas" research note, which examines global economic trends through a series of maps.

The five most populous nations are China (1.37 billion), India (1.2 billion), the US (323 million), Indonesia (256 million), and Brazil (204 million), according to the data cited by BAML.
