Side by side

Population density

Nigeria is 72 times more densely populated than Australia — 257 against 4 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 — Australia on the left, Nigeria on the right.
• Different currencies: the Australian dollar and the Nigerian naira.
• Australia spans 5 time zones, so "local time" there is not a single answer.
• Different continents — Oceania and Africa.

Australia

The sixth-largest country in the world and the only one that covers an entire continent. The Great Barrier Reef runs about 2,300 km and is the largest structure made by living organisms on Earth, visible from orbit. Around eighty percent of its mammals, reptiles and flowering plants exist nowhere else. Melbourne and Sydney are within roughly a hundred thousand people of each other, and which counts as the largest city depends on where the boundary is drawn.

Nigeria

The most populous country in Africa, with roughly one African in six. The Niger Delta is the largest river delta in Africa at about 70,000 km², a maze of creeks and mangrove covering an area the size of Ireland.

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.
