Manila, capital and chief city of the Philippines. The city is the centre of the country’s economic, political, social, and cultural activity. It is located on the island of Luzon and spreads along the eastern shore of Manila Bay at the mouth of the Pasig River. The city’s name, originally Maynilad, is derived from that of the nilad plant, a flowering shrub adapted to marshy conditions, which once grew profusely along the banks of the river; the name was shortened first to Maynila and then to its present form. In 1975, by presidential decree, Manila and its contiguous cities and municipalities were integrated to function as a single administrative region, known as Metropolitan Manila (also called the National Capital Region); the Manila city proper encompasses only a small proportion of that area.
Manila has been the principal city of the Philippines for four centuries and is the centre of its industrial development as well as the international port of entry. It is situated on one of the finest sheltered harbours of the Pacific region, about 700 miles (1,100 km) southeast of Hong Kong. The city has undergone rapid economic development since its destruction in World War II and its subsequent rebuilding; it is now plagued with the familiar urban problems of pollution, traffic congestion, and overpopulation. Measures have been taken, however, to ameliorate those problems. Area city, 15 square miles (38 square km); National Capital Region, 244 square miles (633 square km). Pop. (2000) city, 1,581,082; National Capital Region, 9,932,560; (2010) city, 1,652,171; National Capital Region, 11,855,975.
Manila occupies the low, narrow deltaic plain of the Pasig River, which flows northwestward to Manila Bay. The swampy delta of the southward-flowing Pampanga River lies to the north of the city. Immediately to the northeast and east of the urban region lies a stretch of lowlands, beyond which rise the peaks of the southern range of the Sierra Madre. Laguna de Bay, the large lake from which the Pasig River flows, flanks Metropolitan Manila to the southeast. Enclosing Manila Bay to the west is the mountainous Bataan Peninsula. Although the city’s area is constricted, it is an excellent port site because of its sheltered harbour, its access to inland agricultural areas by way of the river, and its relative proximity to the Asian mainland.
The city is protected from extreme weather conditions by the hills of the Sierra Madre and the mountains of the Bataan Peninsula. The tropical climate is characterized by a wet season that lasts from June to November and by a dry season lasting from December to May. The wettest months are July, August, and September, when thunderstorms are especially common. The average annual rainfall totals about 80 inches (about 2,000 mm). There is little monthly variation from the mean annual temperature, which is in the low 80s F (about 27 °C).
The city is dotted with palms, banyans, acacias, and other tropical trees, and bamboo grows in many public parks. Domestic mammals—such as water buffalo, horses, dogs, pigs, and goats—are common, while wild birdlife includes shrikes, doves, and pigeons. Manila Bay abounds with sardines, anchovies, mackerel, tuna, snappers, and barracuda. The city’s natural beauty is marred, however, by air and water pollution caused by the expansion of industry and the growing number of motor vehicles.
The city is bisected by the Pasig River. It is divided into six administrative divisions that comprise 17 districts. Most of the districts developed from the original fortress city of Intramuros (“Within Walls”) and the 13 villages located outside its walls. About two-thirds of the districts lie to the north of the river and the remaining third lies to the south. The two sections of the city are connected by several bridges.
Although business areas are widespread, the districts to the north of the river—especially along the bay and in the city’s west-central region— constitute the chief centres of trade and commerce. The district of San Miguel is the site of Malacañang Palace, the presidential residence; and several universities are located in Sampaloc, on the northeastern edge of the city. Adjacent to the heavily populated districts on the northern shore is Manila North Harbor; Manila South Harbor, the main international port, is on the southern shore. Intramuros is renowned for its 16th-century San Agustin church as well as for the ruins of its old walls and of Fort Santiago. On the south shore, Ermita and Malate are choice residential districts and the sites of hotels and embassies. The districts to the southeast are generally middle-income residential areas.
Metropolitan Manila includes the cities of Manila, Caloocan City to the north, Quezon City to the northeast, and Pasay City (located near the shore of Manila Bay) to the south and 13 municipalities. The municipalities include Makati, Mandaluyong, San Juan, Las Piñas, Malabon, Navotas, Pasig, Pateros, Parañaque, Marikina, Muntinlupa, Taguig, and Valenzuela. Metropolitan Manila was created in order to provide integrated services such as water supply, police and fire protection, and transport and to permit central planning for simultaneous and unified development.
