American settlement in the Philippines (Filipino: paninirahan sa Pilipinas ng mga Amerikano) began during the Spanish colonial period.

They noted there was a significant mixed population of Amerasians born here since World War II, as well as descendants of Americans from the colonial era.

The Philippine–American War erupted after the U.S. assimilated the Philippines instead of granting independence following Spanish cession to the U.S. in their peace treaty.

Until the mid-1990s, Americans were concentrated in the cities of Angeles and Olongapo, northwest of Metro Manila, because of the large US military bases there.

[13] The colonization period of the Philippines formally ended in 1946, yet scholars continue to debate about the lasting effects of American settlement there.

Some historians of American foreign relations have argued that Philippine formal independence in 1946 was incomplete and unequal, and that there exists a 'dependent' alliance between the two countries.

It has also been argued that historians who have drawn conclusions mainly from hindsight should pay closer attention to contemporary views.

It focused on stigmatization, discrimination, psychosocial risks, and mental disorders among a sample of African and Anglo Amerasians residing in Angeles, site of the Clark Air Force Base.

The paper asserts that the Angeles-Manila-Olongapo Triangle (AMO) contains the highest concentration of biracial Anglo, African and Latino Amerasians in the world.

[26] In addition, there is a population of Filipino Americans, who were born in the United States, who are immigrating to the Philippines, known as "baliktad", meaning backwards.
