The History of Cambodian Population Growth

According to the statement extracted from the NIS 9th conducted Census final report issued in October 2020 of the Cambodia Population Census.

The first Cambodian census was conducted in 1962, following independence from France. It counted a total population of 5.7 million. The demographic situation of the nation changed dramatically after this first census because of war and civil unrest. The country carried out no further census until 1998. However, demographers did make some population estimates to serve as the base population for planning and policy development. A demographic survey conducted in 1979-1980 estimated the total Cambodian population at approximately 6.6 million.

In 1994, the Cambodian Socio-Economic Survey was carried out by the National Institute of Statistics (NIS). The Survey estimated the total population of Cambodia at 9.9 million.

In March 1996, the NIS conducted another demographic survey covering 20,000 households, which estimated the total population of Cambodia at 10.7 million. The 1998 Census recorded a population of 11.4 million.
The NIS also undertook an Inter-Censal Survey in 2004 and found that the population had increased to 12.8 million. Following a pattern of steady increase, the 2008 Census obtained a result of 13.4 million. The Inter-Censal Survey in 2013 revealed a population of 14.7 million and the final result
of GPCC 2019 accounted for 15.6 million.
