1. Overview

#japan #spain #USA

“Spain ceded Guam to the US in 1898. Captured by the Japanese in 1941, it was retaken by the US three years later. The military installation on the island is one of the most strategically important US bases in the Pacific.”

CIA's The World Factbook (2013)₆

“Northern Guam is mainly taken up by the US military´s Andersen Base but the south is a must-see, with its rural kaleidoscope of historical villages, stunning waterfalls and pristine beaches. As Micronesia´s most populous island, Guam is about as `cosmopolitan´ as it gets, so it cops a lot of attitude from Pacific snobs who reckon it lacks `real island culture´. Sure, American accents are everywhere (it´s an unincorporated US territory and many Guamanian homes fly the US flag) and the Chamorro language isn´t spoken quite as widely as it used to be. And if you never stray from Tumon Bay - the island´s glitzy duty-free shopping and accommodation hub - then undeniably you´ll be over- (or under-) whelmed.

But the island is currently in the throes of retooling itself. The tourism authorities talk of how `Product Guam´ (there´s that American influence) needs a complete overhaul from its current status as a Pacific theme park for Japanese tourists. There may come a day soon when Chamorro culture (long subsumed by various invasions and occupations) is promoted above all else, with an increased focus on local food and the fascinating stories underlying many of the villages.”

"The World" by Lonely Planet (2014)₇

As a territory of the USA, this territory does not have standard international statistics available for it in its own right.

2. Guam's Demographics and Migration

Population Datasets:

This country has a fertility rate of 2.55. The fertility rate is, in simple terms, the average amount of children that each woman has. The higher the figure, the quicker the population will grow, although, to calculate the rate you also need to take into account morbidity - the rate at which people die. If people live healthy and long lives and morbidity is low, then, 2.0 approximates to the replacement rate (two new children for each set of parents who die), which would keep the population stable. If all countries had such a fertility rate, population growth would end. The actual replacement rate in most developed countries is around 2.1, once you take mortality into account₈. The highest fertility rate ever detected in a single year was in Yemen in 1985, at 8.86.₉

The countries with the best overall approach to public health, in terms of both public policy and individual lifestyle choices, are Monaco, Liechtenstein and Japan₁₂. These countries are worth emulating. And, although often through no fault of the average citizen, the worst countries are Angola, Somalia and S. Sudan₁₂.

42 datasets are used to calculate points for each country, including multiple decades of data on its average life expectancy, its alcohol consumption rate, its fertility rate, its smoking rate, its suicide rate, its food aid and health contributions and WHO compliance, the prevalence of overweight adults, obesity rate, its adolescent birth rate, delivery rate of infant DTP immunizations, delivery rate of 7x Infant Immunizations 2011-2015 and childhood mortality. The regions with the best average results per country are Scandinavia, Europe and The Mediterranean₁₂, whereas the worst are Micronesia, Africa and Melanesia₁₂.

There isn't much information in the database for Guam, most likely because it is either a part of another country (i.e., a territory or possession) and therefore most international statistics are counted for the country as a whole, or, this is such an exotic place that little data exists about it.
