How we got the density

  1. Density is the one figure on this page that is calculated rather than looked up: population ÷ area.
  2. 69.1 million people = 69,100,000 people. Divided by 242,495 km²: 284.95 people per km², which rounds to 285.

Check it backwards

285 × 242,495 km² ≈ 69,111,075 people — back to the population, apart from the rounding of the density to a whole number.
