Guam Demographics

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.
