Side by side

Population density

United States is 1.7 times more densely populated than Algeria — 35 against 20 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 Algerian dinar and the United States dollar.
• United States spans 6 time zones, so "local time" there is not a single answer.
• Different continents — Africa and North America.

Algeria

The largest country in Africa, and the tenth largest in the world. About four-fifths of it is Sahara, so nearly the whole population lives on the Mediterranean strip in the north. The Hoggar mountains in the deep south rise above 2,900 m and get frost.

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.
