Side by side

Population density

United States is 1325 times more densely populated than Greenland — 35 against 0 people per km². Density is where area and population interact, and it often reverses the impression the headline figures give — a large country with a small population can feel emptier than a small crowded one by an enormous margin.

Practical differences

• Different currencies: the krone and the United States dollar.
• United States spans 6 time zones, so "local time" there is not a single answer.

Greenland

The largest island in the world, and about eighty percent of it is under an ice sheet up to 3 km thick — enough water to raise global sea level roughly 7 m if it all melted. There are no roads between towns; travel is by boat, plane or snow. Its population of under 60,000 lives almost entirely on the ice-free coastal fringe.

United States

Third or fourth largest country in the world depending on how China's area is counted. It spans six standard time zones across the fifty states, from UTC-10 in Hawaii to UTC-5 on the east coast. Death Valley holds the highest reliably recorded air temperature on Earth, 56.7 °C in 1913, and is 86 m below sea level; Denali, 5,500 km away in Alaska, is 6,190 m.

Neutral facts only. Nothing here addresses politics, government, economics or which country is preferable in any respect — population is the one figure that dates, and it carries its year.
