Side by side

Population density

Brazil is 1.5 times more densely populated than Argentina — 25 against 16 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 Argentine peso and the Brazilian real.
• Brazil spans 4 time zones, so "local time" there is not a single answer.

Argentina

The eighth-largest country in the world and the largest Spanish-speaking one. Aconcagua at 6,961 m is the highest mountain outside Asia; the Laguna del Carbón, about 1,000 km away, is 105 m below sea level and the lowest point in the western hemisphere. Ushuaia in Tierra del Fuego is the southernmost city of any size on Earth.

Brazil

The fifth-largest country in the world and the largest in the southern hemisphere. It holds about sixty percent of the Amazon rainforest, and the Amazon River discharges roughly a fifth of all the fresh water that reaches the world's oceans — more than the next seven rivers combined. Brazil borders every South American country except Chile and Ecuador.

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.
