Side by side

Population density

Hong Kong is 195 times more densely populated than United States — 6,768 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

• They drive on opposite sides — Hong Kong on the left, United States on the right.
• Different currencies: the Hong Kong dollar and the United States dollar.
• United States spans 6 time zones, so "local time" there is not a single answer.
• Different continents — Asia and North America.

Hong Kong

One of the most densely populated places on Earth, yet roughly three-quarters of its land is undeveloped countryside and about forty percent is protected country park. It has 263 islands and around 730 km of coastline. There are more skyscrapers over 150 m here than in any other city.

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.
