What the numbers say about Brittany

Brittany covers 4.3% of the area of France and ranks 9th of 18 by population, against 12th by area.
It would take 23.3 regions the size of Brittany to cover France.
The largest, Nouvelle-Aquitaine, is 3.11× the size of Brittany; the smallest, Mayotte, is 1.4% of it.
Closest in size within France: Normandy (30,100 km², 1.10×) and Provence-Alpes-Côte d’Azur (31,300 km², 1.15×).
Counted as a country, Brittany would be larger than 96 of the 239 countries and territories listed on sizeversus, and would rank 144th by area, between Albania (28,300 km²) and the Solomon Islands (27,200 km²).
With 3.4 million people it would rank 135th of 238 by population.
Brittany has 125 people per km², about the density of Syria, which has 128 per km².
That makes Brittany the 8th most densely populated of the 18 regions, 1.17× the average for France (107 per km²).
On a standard web map (Web Mercator), a place at 48°N is drawn about 2.2× too large in area, so Brittany looks bigger there than it is.
Laid out flat, Brittany stretches about 175 km north to south and 303 km east to west.
