Historical background

During the Red Khmer (1975-1979), the urban population was forced out into the countryside. A re-urbanization started in the 1980s. 23.4 percent of the population now live in urban areas.

The civil war and the conditions of the Red Khmer have also led to special peculiarities in the population. A birth explosion that started after the fall of the Red Khmer in 1979 has led to the population being very young. 30.76 percent of the population is under 14. About a quarter of the population still does not have access to clean drinking water, and illiteracy is at 22.8 percent (2015).

97.6 percent of the population is ethnic Khmer, making Cambodia the most homogeneous country in Southeast Asia. Khmers have populated Cambodia since prehistoric times (since before 100 century CE.). Their culture is influenced by intercourse and contact with other cultures, first and foremost Indian culture and religion through civilizations in India and Java, later also with Thais (900th to 14th centuries), Vietnamese (from early 16th century) and Chinese (since the 18th century). The main minority groups cham – Muslims (1.2 percent), Vietnamese (0.1 percent) and Chinese (0.1 percent).


The Khmer people are traditionally Buddhists (theravada). 97.9 percent of the population belongs to this religion, which has played a dominant role in the cultural life of the people. 1.1 percent of the population are Sunni Muslims and 0.5 percent are Christians.


The official language is Khmer, which is the mother tongue of 96.3 percent of the population. Khmer is written with an alphabet developed from the Indian Brahman script. Furthermore, Vietnamese and Chinese are spoken.
