Population density

United Kingdom is 3.7 times more densely populated than Ireland — 285 against 78 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 Euro and the British pound.

Ireland

The interior is a low limestone plain ringed by coastal mountains, which is why the rivers drain inward and the middle of the country is bog. The Cliffs of Moher run 14 km and reach 214 m. Ireland has no native snakes, and only one native reptile.

United Kingdom

Made up of Great Britain, the north-east of Ireland and around 6,000 smaller islands. No point in the UK is more than about 113 km from the sea. Ben Nevis, the highest point, is 1,345 m, which is modest — but the country has around 31,000 km of coastline once every inlet is counted.

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.
