Number of inhabitants between 1961 and 2001 in thousands. Note the decrease during the Khmer Rouge years (1975-1979). FAO Data, Demographics of Cambodia

Between 1874 and 1921, the total population of Cambodia increased from about 946,000 to 2.4 million. By 1950 it had increased to between 3,710, 107 and 4,073,967, and in 1962 it had reached 5.7 million. From the 1960s until 1975, the population of Cambodia increased by about 2.2 % yearly, the lowest increase in Southeast Asia. By 1975 when the Khmer Rouge took power, it was estimated at 7.3 million. Of this total an estimated one million to two million reportedly died between 1975 and 1978. In 1981 the PRK gave the official population figure as nearly 6.7 million, although approximately 6.3 million to 6.4 million is probably a more accurate one. The average annual rate of population growth from 1978 to 1985 was 2.3 % (see table 2, Appendix A). Life expectancy at birth was 44.2 years for males and 43.3 years for females in 1959. By 1970 life expectancy had increased by about 2.5 years since 1945. The greater longevity for females apparently reflected improved health practices during maternity and childbirth.

In 1959 about 45 % of the population was under 15 years of age; by 1962 this figure had increased slightly to 46 %. In 1962 an estimated 52 % of the population was between 15 and 64 years of age, while 2 % was older than 65. The percentage of males and females in the three groups was almost the same.

Note: estimates for this country take into account the effects of excess mortality due to AIDS; this can result in lower life expectancy, higher infant mortality and death rates, lower population growth rates, and changes in the distribution of population by age and sex than would otherwise be expected (July 2006 est.)

Adjective: Cambodian

Khmer 82%, Vietnamese 12%, Cham 4%, other 2%.

Note: The population of Cambodia has been fairly homogeneous. In 1962 about 80 % of the population was ethnic Khmer. The remaining 20 % included Chinese, Vietnamese, Cham, Khmer Loeu, Europeans. By 1981, as a result of the Vietnamese repatriation in 1970 to 1971 and the deaths and emigration of large numbers of Cham and Chinese, ethnic Khmer accounted for about 82 % or more of the population.

Theravada Buddhist 95%, other 5%

Khmer (official) 85%, French, Vietnamese
