What fits

Ningxia is 66% of the size of Hokkaido (Japan).
Hokkaido (Japan) is larger by 26,600 km² (10,300 mi²), which is 51% of the area of Ningxia.
Measured in Belgiums: Hokkaido (Japan) is about 2.57, Ningxia about 1.70.

How they differ

Hokkaido (Japan) is larger, but Ningxia has the larger population: 7.2 million against 5.4 million, 1.33× as many people.
Per square kilometre that is 138 in Ningxia against 69 in Hokkaido (Japan): Ningxia is 2.00× as densely populated.
Their centres are about 3,130 km apart.
A standard web map misstates the comparison: Hokkaido (Japan) at 43°N is drawn about 1.9× too large and Ningxia at 37°N about 1.6×, so the map shows Hokkaido (Japan) as 1.81× the size of Ningxia instead of 1.51×.
Together Hokkaido (Japan) and Ningxia cover 131,000 km², close to the size of Greece (131,000 km², 0.3% bigger).
The gap between them, 26,600 km², is about the size of Equatorial Guinea (26,700 km²).
At Ningxia's density, Hokkaido (Japan) would have 10.9 million people (it has 5.4 million). At Hokkaido (Japan)'s density, Ningxia would have 3.6 million (it has 7.2 million).
Hokkaido (Japan)'s centre is 6.1° of latitude, about 680 km, farther north than Ningxia's.
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.
Ningxia is the 27th largest of the 31 provinces and regions of China and covers 0.6% of its area; it is the 23rd most densely populated of them.
Hokkaido (Japan) lies about 6° of latitude (roughly 681 km) north of Ningxia.
Shared out evenly, each person in Hokkaido (Japan) would have about 14,500 m² and each person in Ningxia about 7,240 m².
Laid side by side, Hokkaido (Japan) and Ningxia would cover 131,000 km², about the same size as Greece.
Together they have 12.6 million people, about as many people as South Sudan.

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.
