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 66% of the size of Pennsylvania.
Pennsylvania is larger by 40,600 km² (15,700 mi²), which is 52% of the area of Hokkaido (Japan).
Measured in Belgiums: Pennsylvania is about 3.89, Hokkaido (Japan) about 2.57.

How they differ

Pennsylvania also has the larger population: 13.0 million against 5.4 million, 2.39× as many people.
Per square kilometre that is 109 in Pennsylvania against 69 in Hokkaido (Japan): Pennsylvania is 1.58× as densely populated.
Their centres are about 9,810 km apart.
Together Pennsylvania and Hokkaido (Japan) cover 198,000 km², close to the size of Kyrgyzstan (199,000 km², 0.4% bigger).
The gap between them, 40,600 km², is about the size of Bhutan (40,400 km²).
At Hokkaido (Japan)'s density, Pennsylvania would have 8.2 million people (it has 13.0 million). At Pennsylvania's density, Hokkaido (Japan) would have 8.6 million (it has 5.4 million).
Hokkaido (Japan)'s centre is 2.5° of latitude, about 280 km, farther north than Pennsylvania's.
Pennsylvania is the 33rd largest of the 51 states and districts of the United States and covers 1.3% of its area; it is the 10th 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 2° of latitude (roughly 275 km) north of Pennsylvania.
Shared out evenly, each person in Pennsylvania would have about 9,180 m² and each person in Hokkaido (Japan) about 14,500 m².
Laid side by side, Pennsylvania and Hokkaido (Japan) would cover 198,000 km², about the same size as Kyrgyzstan.
Together they have 18.4 million people, about as many people as the Netherlands.

Wikidata's official figure of 119,000 km² agrees with our measured area of 119,000 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.
