How they differ
- Rhode Island also has the larger population: 1.1 million against 949,000, 1.16× as many people.
- Per square kilometre that is 512 in Kagawa against 387 in Rhode Island: Kagawa is 1.32× as densely populated.
- Their centres are about 11,200 km apart.
- A standard web map misstates the comparison: Rhode Island at 42°N is drawn about 1.8× too large and Kagawa at 34°N about 1.5×, so the map shows Rhode Island as 1.87× the size of Kagawa instead of 1.53×.
- Together Rhode Island and Kagawa cover 4,690 km², close to the size of Trinidad and Tobago (5,120 km², 9.3% bigger).
- The gap between them, 979 km², is about the size of Åland (942 km²).
- At Kagawa's density, Rhode Island would have 1.5 million people (it has 1.1 million). At Rhode Island's density, Kagawa would have 718,000 (it has 949,000).
- Rhode Island's centre is 7.4° of latitude, about 830 km, farther north than Kagawa's.

- Rhode Island lies about 7° of latitude (roughly 827 km) north of Kagawa.
- Shared out evenly, each person in Rhode Island would have about 2,580 m² and each person in Kagawa about 1,950 m².

- Together they have 2.0 million people, about as many people as Slovenia.
- Kagawa is drawn from 94 points: at a size under 2,500 km² the outline is a sketch, so the overlap shows the proportions rather than the exact shape.

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.
