Pasay, officially the City of Pasay, is a highly urbanized city in the National Capital Region of the Philippines. According to the 2020 census, it has a population of 440,656 people. Due to its location just south of Manila, Pasay quickly became an urban town during the American colonial period. It is now best known for being the site of most of Ninoy Aquino International Airport and of complexes such as Newport City and the SM Central Business Park.
