What the numbers say about Saga
- Saga covers 0.7% of the area of Japan and ranks 41st of 47 by population, against 42nd by area.
- It would take 153 prefectures the size of Saga to cover Japan.
- The largest, Hokkaido (Japan), is 32.2× the size of Saga; the smallest, Kagawa, is 76% of it.
- Closest in size within Japan: Kanagawa (2,380 km², 1.03×) and Tokyo (2,180 km², 1.12×).
- Counted as a country, Saga would be larger than 59 of the 239 countries and territories listed on sizeversus, and would rank 181st by area, between Luxembourg (2,610 km²) and Mauritius (2,000 km²).
- With 810,000 people it would rank 165th of 238 by population.
- Saga has 331 people per km², about the density of Japan, which has 331 per km².
- That makes Saga the 17th most densely populated of the 47 prefectures, 98% of the average for Japan (338 per km²).
- On a standard web map (Web Mercator), a place at 33°N is drawn about 1.4× too large in area, so Saga looks bigger there than it is.
- Laid out flat, Saga stretches about 68 km north to south and 72 km east to west.
- Wikidata's official figure of 2,440 km² agrees with our measured area of 2,450 km², to within 2%.
- Saga is small enough that Natural Earth draws it from only 74 points. Take its shape as a sketch and the official figure as the firmer number.
