Guam 🇬🇺

Guam is one of the territories of Micronesia that appears on world lists without being a UN member state. Its seat of government is Hagåtña.

The population is about 167,777, placing it 191st of 250 by population — between Saint Lucia above it and Curaçao below. Within Micronesia alone it is the 3rd largest of 7 and the 1st most populous.

It covers 549 km², which ranks it 200th of the 250 countries and territories in this dataset — just behind the Isle of Man and just ahead of Andorra. For scale, it is around a fifth smaller than Singapore.

Geography and neighbours of Guam

Its reference point sits at 13.5° north and 144.8° east, which puts it in the northern hemisphere, roughly 1,499 km from the equator, in what geographers would call tropical latitudes.

Countries on the same parallel, far away in longitude, include Sudan, Chad and Yemen.

There is no land frontier at all — every boundary it has is a coastline. That puts it among the 85 entries of 250 here with no land neighbours, so everything and everyone arrives by sea or by air.
