Population

Cambodia’s total population was estimated by the National Institute of Statistics to be 14.68 million in 2013,1 with annual population growth of 1.46 percent. The United Nations, however, estimated that the 2015 population was 15.58 million.2 The last formal census was carried out in 2008.

Some key statistics:3

  • 78 percent of the population live in rural areas
  • Two-thirds of the population are working age (15–64), around 29 percent younger than 15 and around 5 percent 65 and older
  • The average age at marriage is 23.7 years for women and 26.2 years for men; both are marrying later in life than in previous years.
  • Life expectancy at birth is 67 for men and 71 for women.

Censuses

There are three categories of census conducted by the National Institute of Statistics of the Ministry of Planning, in cooperation with relevant institutions:4

  • Population census, which covers the population of the whole country
  • Agricultural census, which covers agricultural statistics of the whole country 
  • Economic census, which covers establishments of businesses and enterprises in the whole country 

The Statistics Law of Cambodia governs everything to do with conducting censuses. Censuses must be conducted at least once every ten years, with inter-censal surveys to facilitate annual updates of census data. This provides accurate and reliable economic and social statistics for government policy makers and other users.

General Cambodia Population Census surveys were conducted in 19985 and in 20086 with financial and technical assistance from the United Nations Population Fund (UNFPA) and Japan International Cooperation Agency (JICA). These censuses recorded:

  • total population
  • growth rates
  • population density
  • total fertility
  • infant and maternal mortality rates
  • literate population
  • age structure
  • mother tongue language
  • ethnic groups
  • religion
  • disability
  • other data.

Censuses are carried out through house-to-house visits over a ten-day period. Everyone staying in Cambodia at census time is counted, including foreigners, although foreign diplomatic corps and their families are excluded. Census results are produced in hard and copy, and also made available through the National Institute of Statistics’ website.

Like other fast developing countries, Cambodia’s growing population is adding more demand to aging and/or inadequate infrastructure, and also adding to the pressure around land issues. In addition, while the majority of the population still live in rural areas, there is an increasing trend towards urbanization, as the country changes from an agrarian-based to a service- and production-based economy.

While Cambodia has had a notably young population since age statistics started to be recorded again in the 1990s following years of civil war, data show an upward trend in life expectancy, which should also continue to lift the median age of the population.
