Manila, the capital of the Philippines, is a densely populated city. It is situated on a bay on the island of Luzon. Manila itself is just one city within the Manila metropolitan area, yet it lends its name to this entire urban agglomeration.
The Manila Metropolitan Area—officially known as the National Capital Region (NCR)—serves as the capital region of the Philippines. It encompasses the City of Manila, along with 15 other cities and the municipality of Pateros. The city is surrounded by the various cities and municipalities of the Metro Manila region: Navotas, Caloocan, Malabon, and Valenzuela to the north; Quezon and Marikina to the northeast; San Juan, Pasig, and Mandaluyong to the east; Makati and Pateros to the southeast; and Pasay, Taguig, and Parañaque to the south. Quezon is the largest, most populous (with approximately 3 million inhabitants), and wealthiest city within the greater Metro Manila area. The Manila metropolitan area constitutes the political, economic, and cultural hub of the Philippines. In everyday parlance, the term "Metro Manila" is frequently used, as it is the designation recognized internationally.
