Overview
Guam is a recognised territory located in Oceania, specifically within the Micronesia subregion. It covers approximately 549 km² and is home to an estimated 153,836 people. The country has coastline along international waters, which has shaped its trade routes, climate, cuisine, and cultural exchanges with the rest of the world. Its capital is Hagåtña, which serves as the political and (in most cases) economic centre of the country, hosting the seat of government and the principal international airport.
This profile pulls together the structured facts that most readers want at a glance — capital, currency, languages, borders — and links onward to the maps and neighbouring countries you are likely to need next. Every figure on this page is rendered server-side from a single dataset, so what you see here matches the regional indexes, statistics rankings, and continental hubs elsewhere on MapVista.
For travellers, students, journalists, and the merely curious, the goal is simple: a single readable page per country that answers the questions you actually asked, without redirecting you to a sign-up screen or a paywall. Citizens of Guam are commonly described as Guamanian, a demonym you will encounter in news coverage and academic writing alike.
Geography & borders
Guam is a microstate, covering approximately 549 km² of land in Oceania (specifically the Micronesia subregion). The country has coastline along international waters, which has shaped its trade routes, climate, and cultural exchanges with the rest of the world. Its approximate geographic centre lies at 13.47° N, 144.78° E, placing it in the northern hemisphere on a line with several other Micronesia nations. Guam has no land borders and is reached entirely by sea or air, a status it shares with the world's other island nations and isolated peninsulas.
No land borders are recorded — this is typical of island nations, archipelagos, and microstates that lack land neighbours, with the open ocean serving as the country's only frontier.

People, demographics & density
With an estimated 153,836 residents, Guam is one of the smallest populations of any sovereign state. That works out to roughly 280.2 people per square kilometre, a comfortably populated density that supports both major cities and a productive countryside. The capital, Hagåtña, anchors the country's political and often economic life and is usually the first city most international visitors encounter. Citizens of Guam are commonly described as Guamanian.
Compared with the global mean of roughly 60 people per square kilometre, Guam's figure of 280.2 people / km² places it well above the global average — closer to a typical European or East-Asian density.
Languages, currency & culture
Culturally, Chamorro, English, and Spanish are recognised as official or co-official languages in Guam, while United States dollar (USD) is the official currency. Like every country in the catalogue, the linguistic situation on the ground is often more layered than the official picture, with regional languages, immigrant communities, and minority tongues woven through everyday life.

Language and currency data are drawn from open sources and reflect the official position rather than the full sociolinguistic picture on the ground. Many countries recognise minority and regional languages in addition to the official ones listed here, and some use multiple currencies in practice — particularly in border regions and tourist economies.

About this profile
This page is one of 250 country profiles on MapVista. The structured facts are sourced from open datasets that aggregate official records — see our methodology for the full list of sources and how we handle disputes, succession, and edge cases. The narrative paragraphs are written to give context to the numbers, but the figures themselves are not invented; if a value is missing it is shown as a dash rather than a guess.
If you spot an out-of-date figure or a misclassification, please reach us via the contact page. We refresh the underlying dataset regularly and corrections are applied at the next rebuild.
