Guam in the Nations Inquiry Country Index

Guam appears in 87 of the statistics tracked here, but is not placed in the Country Index: the index needs a standing on three quarters of its topics, and Guam is measured on too few of them. Every published reading below is unaffected.

About Guam

Guam, a United States territory that elects its own governor and legislature, lies at the southern end of the Mariana Islands, in the north-western Pacific. Limestone cliffs such as Two Lovers Point edge its northern plateau; the south is volcanic, with red hills and waterfalls. Offshore runs the Mariana Trench, the deepest part of the world’s oceans. The brown tree snake, which arrived in military cargo after the Second World War, wiped out most of the native forest birds.

The CHamoru people’s ancestors sailed from Island Southeast Asia some three and a half thousand years ago, and their descendants raised houses on latte, stone pillars crowned with capstones. Magellan’s ships stopped here in March 1521. After Spain claimed Guam in 1565, war and disease devastated the CHamoru. The United States took the island in 1898; Japan held it from December 1941 until American forces returned in July 1944, marked each year as Liberation Day. The Organic Act of 1950 made its people US citizens.

Catholic village fiestas for patron saints gather whole families, and chenchule’, the custom of giving to one another at weddings and funerals, binds them. A CHamoru table holds red rice coloured with achote seeds and kelaguen, chicken or fish cured in lemon juice with grated coconut and hot pepper. Visitors from Japan and South Korea fill the hotels on Tumon Bay, and the naval base at Apra Harbor and Andersen Air Force Base make the military the other mainstay.

03Highs and lows

Where Guam stands out

The two ends of its own record: every statistic on which Guam sits within ten places of the best or worst in the world, plus its strongest and weakest readings overall. Each is turned into a percentile — its place among every country measured — which is what lets a hunger score and a press-freedom rank be compared at all.

Where Guam does best5

In the top third of all countries measured. 1 is within ten places of the best in the world, in a field of at least 50 countries — marked with that place.

A band is a place among the countries each publisher scores, so Guam can move because other countries moved. See the Country Index for the full method.

Sources and how to read them

How to read this page

  • The scores and ranks belong to their publishers. Nothing is adjusted, rescaled or re-ranked; each is reproduced from the edition named beside it. Where a row says position · derived, the publisher ranks nobody on that measure and the position is ours, made by ordering the published score.
  • Each statistic shows its newest edition, which is not always the edition the Country Index uses: the index pins every source to one data year so its average compares like with like.

How a standing is built from percentiles, why Guam can move because other countries moved, and why publishers measure between 120 and 215 countries each are set out in full in how a standing is made and what a standing cannot tell you.
