How we got the density
- Density is the one figure on this page that is calculated rather than looked up: population ÷ area.
- 71.7 million people = 71,700,000 people. Divided by 513,120 km²: 139.73 people per km², which rounds to 140.

140 × 513,120 km² ≈ 71,682,864 people — back to the population, apart from the rounding of the density to a whole number.
