 The Americans, until the mid-1990s, had a heavy presence in the cities of Angeles and Olongapo, northeast of Metro Manila, due to the presence of large US military bases there.During the American colonial period (1898–1946), a recorded number of more than 800,000 Americans were born in the Philippines.Large concentrations of Filipinos with American ancestry aside from Metro Manila are located in the areas of the former US bases such as the Subic Bay area in Zambales and Clark Field in Angeles.
