How they differ

Coahuila is larger, but Hokkaido (Japan) has the larger population: 5.4 million against 3.0 million, 1.84× as many people.
Per square kilometre that is 69 in Hokkaido (Japan) against 20 in Coahuila: Hokkaido (Japan) is 3.52× as densely populated.
Their centres are about 9,770 km apart.
A standard web map misstates the comparison: Coahuila at 27°N is drawn about 1.3× too large and Hokkaido (Japan) at 43°N about 1.9×, so the map shows Coahuila as 1.28× the size of Hokkaido (Japan) instead of 1.92×.
Together Coahuila and Hokkaido (Japan) cover 230,000 km², close to the size of Laos (228,000 km², 0.7% smaller).
The gap between them, 72,200 km², is about the size of Sierra Leone (71,600 km²).
At Hokkaido (Japan)'s density, Coahuila would have 10.4 million people (it has 3.0 million). At Coahuila's density, Hokkaido (Japan) would have 1.5 million (it has 5.4 million).
Hokkaido (Japan)'s centre is 16.1° of latitude, about 1,790 km, farther north than Coahuila's.
Coahuila is the 3rd largest of the 32 states of Mexico and covers 7.7% of its area; it is the 27th 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 16° of latitude (roughly 1,790 km) north of Coahuila.
Shared out evenly, each person in Coahuila would have about 51,090 m² and each person in Hokkaido (Japan) about 14,500 m².

Wikidata's official figure of 152,000 km² agrees with our measured area of 151,000 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.
