Here's a breakdown:
* Filipino ancestry: Guam has a large Filipino population due to historical migration patterns and the strong cultural ties between the two islands. Filipinos comprise the largest ethnic group on Guam, accounting for roughly 30% of the population.
* Chamorro heritage: The indigenous people of Guam are the Chamorros, who have inhabited the island for centuries. Chamorros make up a significant portion of the population, estimated at around 37%.
* Other ancestries: Guam also has a diverse population with people of various other ancestries, including:
* Spanish: Guam was a Spanish colony for centuries, leaving a lasting legacy in the culture and language.
* American: After the Spanish-American War, Guam became a US territory, resulting in a significant American population.
* Japanese: A smaller but notable Japanese population exists, particularly in the north of the island.
* Micronesian: Other Micronesian islanders, including Palauans and Chuukese, have migrated to Guam.
In summary, while Filipino ancestry is prominent in Guam, it is not the sole or even the dominant ancestry. The island's population is a vibrant mix of various backgrounds, with Chamorro heritage playing a crucial role in Guam's unique identity.
