What the numbers say about Fukuoka

Fukuoka covers 1.4% of the area of Japan and ranks 9th of 47 by population, against 28th by area.
It would take 73.9 prefectures the size of Fukuoka to cover Japan.
The largest, Hokkaido (Japan), is 15.6× the size of Fukuoka; the smallest, Kagawa, is 37% of it.
Closest in size within Japan: Chiba (5,110 km², 1.01×) and Aichi (4,940 km², 1.02×).
Counted as a country, Fukuoka would be larger than 65 of the 239 countries and territories listed on sizeversus, and would rank 175th by area, between Trinidad and Tobago (5,120 km²) and Cape Verde (3,930 km²).
With 5.1 million people it would rank 125th of 238 by population.
Fukuoka has 1,011 people per km², about the density of Bangladesh, which has 1,252 per km².
That makes Fukuoka the 7th most densely populated of the 47 prefectures, 2.99× the average for Japan (338 per km²).
Wikidata holds no 2021 figure for Fukuoka; the 2020 figure is the only one it has, so Fukuoka is not counted the same way as the 38 prefectures that carry 2021.
On a standard web map (Web Mercator), a place at 34°N is drawn about 1.4× too large in area, so Fukuoka looks bigger there than it is.
Laid out flat, Fukuoka stretches about 110 km north to south and 108 km east to west.
Wikidata's official figure of 4,970 km² agrees with our measured area of 5,050 km², to within 2%.
