  The French protectorate of Cambodia conducted its first official census in 1921. Only men aged 20 to 60 were counted, as its purpose was for the collection of taxes. After the 1962 population census was conducted, Cambodia's civil conflicts and instability lead to a 36-year-long gap before the country could have another official census in 1998.
  
  As of 2010, half of the Cambodian population is younger than 22 years old. At a 1.04 female to male ratio, Cambodia has the most female-biased sex ratio in the Greater Mekong Subregion. Among the Cambodian population aged over 65, the female to male ratio is 1.6:1.
  
  The total fertility rate in Cambodia was 2.5 children per woman in 2018. The fertility rate was 4.0 children in 2000. Women in urban areas have 2.2 children on average, compared with 3.3 children per woman in rural areas. Fertility is highest in Mondol Kiri and Rattanak Kiri Provinces, where women have an average of 4.5 children, and lowest in Phnom Penh where women have an average of 2.0 children.
