## Population density

Vietnam is 8.8 times more densely populated than United States — 307 against 35 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 United States dollar and the Vietnamese đồng.
- United States spans 6 time zones, so "local time" there is not a single answer.
- Different continents — North America and Asia.

## 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.

## Vietnam

Long and narrow: about 1,650 km from north to south and under 50 km wide at the waist. Hang Sơn Đoòng in Phong Nha is the largest known cave passage in the world, big enough to hold a New York block of 40-storey buildings, with its own river, jungle and clouds. Hạ Long Bay holds roughly 1,600 limestone karst islands.
