Vietnam is located on the eastern Indochina Peninsula between the latitudes 8° and 24°N, and the longitudes 102° and 110°E. It covers a total area of approximately 331,210 km2 (127,881 sq mi), making it almost the size of Germany. The combined length of the country's land boundaries is 4,639 km (2,883 mi), and its coastline is 3,444 km (2,140 mi) long. At its narrowest point in the central Quảng Bình Province, the country is as little as 50 kilometres (31 mi) across, though it widens to around 600 kilometres (370 mi) in the north. Vietnam's land is mostly hilly and densely forested, with level land covering no more than 20%. Mountains account for 40% of the country's land area, and tropical forests cover around 42%.

The northern part of the country consists mostly of highlands and the Red River Delta. Phan Xi Păng, located in Lào Cai Province, is the highest mountain in Vietnam, standing 3,143 m (10,312 ft) high. Southern Vietnam is divided into coastal lowlands, the mountains of the Annamite Range, and extensive forests. Comprising five relatively flat plateaus of basalt soil, the highlands account for 16% of the country's arable land and 22% of its total forested land. The soil in much of southern Vietnam is relatively poor in nutrients.

The Red River Delta, a flat, roughly triangular region covering 15,000 km2 (5,792 sq mi), is smaller but more intensely developed and more densely populated than the Mekong River Delta. Once an inlet of the Gulf of Tonkin, it has been filled in over the millennia by riverine alluvial deposits. The delta, covering about 40,000 km2 (15,444 sq mi), is a low-level plain no more than 3 meters (9.8 ft) above sea levelat any point. It is criss-crossed by a maze of rivers and canals, which carry so much sediment that the delta advances 60 to 80 meters (196.9 to 262.5 ft) into the sea every year.

Ecology and biodiversity

The saola, one of the world's rarest mammals, is native to Vietnam.

Vietnam lies in the Indomalaya ecozone. According to the 2005 National Environmental Present Condition Report. Vietnam is one of twenty-five countries considered to possess a uniquely high level of biodiversity. It is ranked 16th worldwide in biological diversity, being home to approximately 16% of the world's species. 15,986 species of flora have been identified in the country, of which 10% are endemic, while Vietnam's fauna include 307 nematode species, 200 oligochaeta, 145 acarina, 113 springtails, 7,750 insects, 260 reptiles, 120 amphibians, 840 birds and 310 mammals, of which 100 birds and 78 mammals are endemic.

Vietnam is furthermore home to 1,438 species of freshwater microalgae, constituting 9.6% of all microalgae species, as well as 794 aquatic invertebrates and 2,458 species of sea fish. In recent years, 13 genera, 222 species, and 30 taxa of flora have been newly described in Vietnam. Six new mammal species, including the saola, giant muntjac and Tonkin snub-nosed monkey have also been discovered, along with one new bird species, the endangered Edwards's pheasant. In the late 1980s, a small population of Javan rhinoceros was found in Cát Tiên National Park. However, the last individual of the species in Vietnam was reportedly shot in 2010.

In agricultural genetic diversity, Vietnam is one of the world's twelve original cultivar centers. The Vietnam National Cultivar Gene Bank preserves 12,300 cultivars of 115 species. The Vietnamese government spent US$49.07 million on the preservation of biodiversity in 2004 alone, and has established 126 conservation areas, including 28 national parks.


As of 2014, the population of Vietnam as standing at approximately 90.7 million people. The population had grown significantly from the 1979 census, which showed the total population of reunified Vietnam to be 52.7 million.[126] In 2012, the country's population was estimated at approximately 90.3 million. Currently, the total fertility rate of Vietnam is 1.8 (births per woman),[ which is largely due to the government'sf amily planning policy, the two-child policy.


According to the 2009 census, the dominant Viet or Kinh ethnic group constituted nearly 73.6 million people, or 85.8% of the population. The Kinh population is concentrated mainly in the alluvial deltas and coastal plains of the country. A largely homogeneous social and ethnic group, the Kinh possess significant political and economic influence over the country. However, Vietnam is also home to 54 ethnic minority groups, including the Hmong, Dao, Tay, Thai, and Nùng. Many ethnic minorities – such as the Muong, who are closely related to the Kinh – dwell in the highlands, which cover two-thirds of Vietnam's territory. Before the Vietnam War, the population of the Central Highlands was almost exclusively Degar (including over 40 tribal groups); however, Ngô Đình Diệm's South Vietnamese government enacted a program of resettling Kinh in indigenous areas. The Hoa (ethnic Chinese) and Khmer Krom people are mainly lowlanders. As Sino-Vietnamese relations soured in 1978 and 1979, some 450,000 Hoa left Vietnam.
