[[File:Cambodia-demography.svg|thumb|Population development]]
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, the population was estimated at 7.3 million. Of this total an estimated one 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 more accurate.

The average annual rate of population growth from 1978 to 1985 was 2.3% (see table 2, Appendix A). A post-Khmer Rouge baby boom pushed the population above 10 million, although growth has slowed in recent years.

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

===Infant and childhood mortality===
Childhood mortality rates are decreasing in Cambodia.<ref name="CDHS"/> Currently, the infant mortality rate is 45 deaths per 1,000 live births for the five-year period before the survey compared with 66 deaths reported in the 2005 CDHS and 95 in the 2000 CDHS. Under-five mortality rates have also decreased from 124 deaths per 1,000 live births in 2000, 83 deaths in 2005 to 54 deaths per 1,000 in 2010.

Childhood mortality decreases markedly with mother's education and wealth. Infant mortality, for example, is twice as high among children whose mothers have no schooling compared to those with secondary or higher education (72 versus 31). The association with wealth is even stronger. There are 77 deaths per 1,000 live births among infants from the poorest households compared to only 23 deaths per 1,000 live births among infants from the richest households.

Mortality rates are much higher in rural than urban areas. Infant mortality, for example, is 64 deaths per 1,000 live births in rural areas compared to only 22 in urban areas.
Mortality also differs by province. Infant mortality ranges from only 13 deaths per 1,000 live births in Phnom Penh to 78 deaths per 1,000 live births in Kampong Chhnang and Svay Rieng.

===Life expectancy===
[[File:Life expectancy of Cambodia.svg|thumb|Life expectancy in Cambodia]]
In 1959, life expectancy at birth was 44.2 years for males and 43.3 years for females. 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.

==Ethnic groups==
[[File:Cambodia ethnic map-en.svg|thumb|450px|An ethnic map of Cambodia from 1972.]]
{{Further|Ethnic groups in Cambodia}}

The largest of the ethnic groups in Cambodia are the [[Khmer people|Khmer]], who comprise 95.8% of the total population<ref name=":0" /> in 2019 and primarily inhabit the lowland Mekong sub region and the central plains.

The Khmer historically have lived near the [[Mekong River|lower Mekong River]] in a contiguous arc that runs from the southern [[Khorat Plateau]] where modern-day [[Thailand]], [[Laos]] and [[Cambodia]] meet in the northeast, stretching southwest through the lands surrounding [[Tonle Sap]] lake to the [[Cardamom Mountains]], then continues back southeast to the mouth of the Mekong River in southeastern [[Vietnam]].

Ethnic groups in Cambodia other than the politically and socially dominant Khmer are classified as either "indigenous ethnic minorities" or "non-indigenous ethnic minorities". The indigenous ethnic minorities, more commonly collectively referred to as the [[Khmer Loeu]] ("upland Khmer"), constitute the majority in the remote mountainous provinces of [[Ratanakiri Province|Ratanakiri]], [[Mondulkiri Province|Mondulkiri]] and [[Stung Treng Province|Stung Treng]] and are present in substantial numbers in [[Kratie Province]].

Approximately 17-21 separate ethnic groups, most of whom speak [[Austroasiatic languages]] related to [[Khmer language|Khmer]], are included in the Khmer Loeu designation, including the [[Kuy people|Kuy]] and [[Tampuan people]]. These peoples are considered by the Khmer to be the aboriginal inhabitants of the land. Two of these highland groups, the [[Rade people|Rade]] and the [[Jarai people|Jarai]], are [[Chamic peoples]] who speak [[Austronesian languages]] descended from ancient [[Cham language|Cham]]. These indigenous ethnic minorities haven't integrated into Khmer culture and follow their traditional animist beliefs.

{{anchor|Immigration}}
The non-indigenous ethnic minorities include immigrants and their descendants who live among the Khmer and have adopted, at least nominally, Khmer culture and language. The three groups most often included are the [[Chinese Cambodian]]s, [[Vietnamese people|Vietnamese]] and [[Cham people|Cham]] peoples. The [[Chinese people|Chinese]] have immigrated to Cambodia from different regions of China throughout Cambodia's history, integrating into Cambodian society and today Chinese Cambodians or Cambodians of mixed Sino-Khmer ancestry dominate the business community, politics and the media. The Cham are descendants of refugees from the various wars of the historical kingdom of [[Champa]]. The Cham live amongst the Khmer in the central plains but in contrast to the Khmer who are Theravada Buddhists, the vast majority of Cham follow Islam.<ref>{{cite web |url=http://www.cambodia-travel.com/information/ethnic-groups.htm |title=Cambodia Ethnic Groups |publisher=Cambodia-travel.com |access-date=2012-09-02 |archive-date=3 October 2018 |archive-url=https://web.archive.org/web/20181003083345/http://www.cambodia-travel.com/information/ethnic-groups.htm |url-status=dead }}</ref>

There are also small numbers of other minority groups. [[Tai peoples]] in Cambodia include the [[Lao people|Lao]] along the Mekong at the northeast border, [[Thai people|Thai]] (urban and rural), and the culturally Burmese [[Kula people (Asia)|Kola]], who have visibly influenced the culture of [[Pailin Province]]. Even smaller numbers of recent [[Hmong people|Hmong]] immigrants reside along the Lao border and various [[List of ethnic groups in Myanmar|Burmese people]]s have immigrated to the capital, Phnom Penh.
