Side by side

Population density

India is 1.5 times more densely populated than Vietnam — 445 against 307 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 — India on the left, Vietnam on the right.
• Different currencies: the Indian rupee and the Vietnamese đồng.

India

The most populous country in the world since 2023. The Ganges-Brahmaputra system drains the southern Himalaya into the largest delta on Earth, and Mawsynram and Cherrapunji in Meghalaya are the wettest inhabited places on record, with roughly 11 m of rain a year. Mumbai is the largest individual municipality; the Delhi urban agglomeration, which contains the capital, is larger still at around 33 million.

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.

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.
