Side by side

Population density

Vietnam is 15 times more densely populated than New Zealand — 307 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

• They drive on opposite sides — New Zealand on the left, Vietnam on the right.
• Different currencies: the New Zealand dollar and the Vietnamese đồng.
• New Zealand spans 2 time zones, so "local time" there is not a single answer.
• Different continents — Oceania and Asia.

New Zealand

Two main islands and around 600 smaller ones, roughly 1,600 km long. New Zealand broke away from Gondwana about 80 million years ago and had no land mammals except bats until people arrived, which is why so many of its birds are flightless. The Southern Alps run most of the South Island and reach 3,724 m at Aoraki / Mount Cook.

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.
