Side by side

Population density

South Korea is 3.5 times more densely populated than China — 518 against 147 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 Chinese yuan and the South Korean won.

China

The largest country in the world using a single time zone, so the sun rises in the far west around three hours later by the clock than in Beijing. China has a land border with fourteen countries — more than any other state except Russia, which also has fourteen. Its terrain runs from Mount Everest on the Nepalese border to the Turpan Depression at 154 m below sea level.

South Korea

About seventy percent mountain, so the population is packed into the valleys and coastal plains; the Seoul metropolitan area holds roughly half the country. Jeju Island is a shield volcano whose lava tube system is among the finest in the world. South Korea has the fastest average internet connections of any large country.

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.
