The Philippines, officially known as the Republic of the Philippines, is a sovereign island country in Southeast Asia situated in the western Pacific Ocean. It consists of 7,107 islands that are categorized broadly under three main geographical divisions: Luzon, Visayas, and Mindanao. Its capital city is Manila while its most populous city is Quezon City; both are part of Metro Manila.

To the north of the Philippines across the Luzon Strait lies China's Taiwan; Vietnam sits west across the South China Sea; southwest is the island of Borneo across the Sulu Sea, and to the south the Celebes Sea separates it from other islands of Indonesia; while to the east it is bounded by the Philippine Sea and the island-nation of Palau. Its location on the Pacific Ring of Fire and close to the equator makes the Philippines prone to earthquakes and typhoons, but also endows it with abundant natural resources and some of the world's greatest biodiversity. At approximately 300,000 square kilometers (115,831 sq mi), the Philippines is the 64th-largest country in the world.

With a population of about 100 million people, the Philippines is the seventh-most populated country in Asia and the 12th most populated country in the world. An additional 12 million Filipinos live overseas, comprising one of the world's largest diasporas. Multiple ethnicities and cultures are found throughout the islands. In prehistoric times, Negritos were some of the archipelago's earliest inhabitants. They were followed by successive waves of Austronesian peoples. Various nations were established under the rule of Datus, Rajahs, Sultans or Lakans. Trade with Chinese, Malay, Indian, and Islamic states also occurred.

The Philippines is an archipelago of 7,107 islands with a total land area, including inland bodies of water, of approximately 300,000 square kilometers (115,831 sq mi). Its 36,289 kilometers (22,549 mi) of coastline makes it the country with the 5th longest coastline in the world.
Situated on the western fringes of the Pacific Ring of Fire, the Philippines experiences frequent seismic and volcanic activity. The Benham Plateau to the east in the Philippine Sea is an undersea region active in tectonic subduction. Around 20 earthquakes are registered daily, though most are too weak to be felt. The last major earthquake was the 1990 Luzon earthquake. There are many active volcanoes such as the Mayon Volcano, Mount Pinatubo, and Taal Volcano. The eruption of Mount Pinatubo in June 1991 produced the second largest terrestrial eruption of the 20th century. Not all notable geographic features are so violent or destructive. A more serene legacy of the geological disturbances is the Puerto Princesa Subterranean River, the area represents a habitat for biodiversity conservation, the site also contains a full mountain-to-the-sea ecosystem and has some of the most important forests in Asia.

Due to the volcanic nature of the islands, mineral deposits are abundant. The country is estimated to have the second-largest gold deposits after South Africa and one of the largest copper deposits in the world. It is also rich in nickel, chromite, and zinc. Despite this, poor management, high population density, and environmental consciousness have resulted in these mineral resources remaining largely untapped. Geothermal energy, however, is another product of volcanic activity that the country has harnessed more successfully. The Philippines is the world's second-biggest geothermal producer behind the United States, with 18% of the country's electricity needs being met by geothermal power.

Climate
Typhoon Megi (also known as Juan) over the Philippines. The Philippines has a tropical maritime climate and is usually hot and humid. There are three seasons: tag-init or tag-araw, the hot dry season or summer from March to May; tag-ulan, the rainy season from June to November; and tag-lamig, the cool dry season from December to February. The southwest monsoon (from May to October) is known as the Habagat, and the dry winds of the northeast monsoon (from November to April), the Amihan. Temperatures usually range from 21 °C (70 °F) to 32 °C (90 °F) although it can get cooler or hotter depending on the season. The coolest month is January; the warmest is May.

The average yearly temperature is around 26.6 °C (79.9 °F). In considering temperature, location in terms of latitude and longitude is not a significant factor. Whether in the extreme north, south, east, or west of the country, temperatures at sea level tend to be in the same range. Altitude usually has more of an impact. The average annual temperature of Baguio at an elevation of 1,500 meters (4,900 ft) above sea level is 18.3 °C (64.9 °F), making it a popular destination during hot summers.

Sitting astride the typhoon belt, most of the islands experience annual torrential rains and thunderstorms from July to October, with around nineteen typhoons entering the Philippine area of responsibility in a typical year and eight or nine making landfall. Annual rainfall measures as much as 5,000 millimeters (200 in) in the mountainous east coast section but less than 1,000 millimeters (39 in) in some of the sheltered valleys. The wettest known tropical cyclone to impact the archipelago was the July 1911 cyclone, which dropped over 1,168 millimeters (46.0 in) of rainfall within a 24-hour period in Baguio. Bagyo is the local term for a tropical cyclone in the Philippines

Demographic
The population of the Philippines increased from 1990 to 2008 by approximately 28 million, a 45% growth in that time frame. The first official census in the Philippines was carried out in 1877 and recorded a population of 5,567,685. As of 2013, the Philippines has become the world's 12th most populous nation, with a population of over 100 million. It is estimated that half of the population resides on the island of Luzon. The population growth rate between 1995 to 2000 of 3.21% decreased to an estimated 1.95% for the 2005 to 2010 period, but remains a contentious issue. The population's median age is 22.7 years with 60.9% aged from 15 to 64 years old. Life expectancy at birth is 71.94 years, 75.03 years for females and 68.99 years for males. There are about 12 million Filipinos outside the Philippines. Since the liberalization of United States immigration laws in 1965, the number of people in the United States having Filipino ancestry has grown substantially. In 2007 there were an estimated 12 million Filipinos living overseas.According to the official, the population of Philippines hit 100 million at the time of midnight on July 27, 2014, made the country become 12th country which has over 100 million.
