What the numbers say about Kagawa
- Kagawa covers 0.5% of the area of Japan and ranks 38th of 47 by population, against 47th by area.
- It would take 202 prefectures the size of Kagawa to cover Japan.
- The largest, Hokkaido (Japan), is 42.5× the size of Kagawa, the smallest of the 47.
- Closest in size within Japan: Osaka (1,860 km², 1.00×) and Okinawa (2,150 km², 1.16×).
- Counted as a country, Kagawa would be larger than 58 of the 239 countries and territories listed on sizeversus, and would rank 182nd by area, between Mauritius (2,000 km²) and the Comoros (1,670 km²).
- With 949,000 people it would rank 162nd of 238 by population.
- Kagawa has 512 people per km², about the density of Burundi, which has 506 per km².
- That makes Kagawa the 11th most densely populated of the 47 prefectures, 1.52× the average for Japan (338 per km²).
- Wikidata holds no 2021 figure for Kagawa; the 2020 figure is the only one it has, so Kagawa 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 1.5× too large in area, so Kagawa looks bigger there than it is.
- Laid out flat, Kagawa stretches about 62 km north to south and 81 km east to west.
- Wikidata's official figure of 1,860 km² agrees with our measured area of 1,850 km², to within 2%.
- Kagawa is small enough that Natural Earth draws it from only 94 points. Take its shape as a sketch and the official figure as the firmer number.
