Guam is an organized, unincorporated territory of the United States in the Pacific Ocean, and one of 5 US territories with an established civilian government. Guam is also the largest, southernmost Mariana Island. Interestingly, there are no true cities in Guam, as the largest village of Dededo has just 45,000 people. Hagåtña, the capital, is the second smallest village in Guam in terms of population and area with just 1,200 people, despite being one of the country's biggest commercial districts and seat of government.
Guam was first inhabited by the Chamorros going back about 4,000 years, and it has a long history of European colonialism, beginning with Spain establishing a colony in 1668. It was occupied by the Japanese for more than two years at the beginning of World War II. The native Chamorros remain the largest ethnic group in the country, accounting for 37% of the population, with 75,000 living in various areas of the United States. Filipinos account for 25.5% of the population, followed by Whites (10%), usually of Spanish or European American ancestry. 85% of the population practices Roman Catholicism.
