Hokkaido (Japan)

Hokkaido (Japan): Part of this region's boundary is disputed with Russia. Size Versus draws Natural Earth's de facto outline, the boundary as it is held on the ground, and takes no position on it.

What fits

Hokkaido (Japan) is 57% of the size of Arkansas.
Arkansas is larger by 58,800 km² (22,700 mi²), which is 75% of the area of Hokkaido (Japan).
Measured in Belgiums: Arkansas is about 4.48, Hokkaido (Japan) about 2.57.

How they differ

Arkansas is larger, but Hokkaido (Japan) has the larger population: 5.4 million against 3.0 million, 1.80× as many people.
Per square kilometre that is 69 in Hokkaido (Japan) against 22 in Arkansas: Hokkaido (Japan) is 3.15× as densely populated.
Their centres are about 9,680 km apart.
A standard web map misstates the comparison: Arkansas at 35°N is drawn about 1.5× too large and Hokkaido (Japan) at 43°N about 1.9×, so the map shows Arkansas as 1.37× the size of Hokkaido (Japan) instead of 1.75×.
Together Arkansas and Hokkaido (Japan) cover 216,000 km², close to the size of Guyana (211,000 km², 2.4% smaller).
The gap between them, 58,800 km², is about the size of Togo (56,900 km²).
At Hokkaido (Japan)'s density, Arkansas would have 9.5 million people (it has 3.0 million). At Arkansas's density, Hokkaido (Japan) would have 1.7 million (it has 5.4 million).
Hokkaido (Japan)'s centre is 8.5° of latitude, about 940 km, farther north than Arkansas's.
Arkansas is the 27th largest of the 51 states and districts of the United States and covers 1.5% of its area; it is the 37th most densely populated of them.
Hokkaido (Japan) is the largest of the 47 prefectures of Japan and covers 21% of its area; it is the 47th most densely populated of them.
Hokkaido (Japan) lies about 8° of latitude (roughly 943 km) north of Arkansas.
Shared out evenly, each person in Arkansas would have about 45,670 m² and each person in Hokkaido (Japan) about 14,500 m².
Laid side by side, Arkansas and Hokkaido (Japan) would cover 216,000 km², about the same size as Guyana.
Together they have 8.4 million people, about as many people as Honduras.

Wikidata's official figure of 138,000 km² agrees with our measured area of 138,000 km², to within 2%.
Our measured 78,800 km² is 5.6% below Wikidata's official figure of 83,400 km². Official figures can include inland water or count land that an outline draws differently. This difference is flagged for review.

Sources and method

Outlines: Natural Earth, 1:10m Admin 1 - States, Provinces, public domain
Boundary: De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
Area: Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
Drawing: Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
