Basic History of Cambodia

cambodia_mapCambodia, which became independent from France in November 1953, is now a multiparty democracy under a constitutional monarchy promulgated in 1993. Before being a democracy, Cambodia had its deathly years under the dictatorship of Pol Pot, a communist revolutionary who led the Khmer Rouge (the name given to the followers of the Communist Party of Kampuchea in Cambodia) from 1963 until his death in 1998. Pot’s rule became known as the era of the “killing fields” when the cities were emptied and about quarter of the country’s 8 million people were slaughtered by the Khmer Rouge. More precisely, Pol Pot’s name came to symbolize the deaths of 2 million people under his rule in Cambodia for four horrific years: 1975 to 1979. Ruled by King Norodom Sihamoni (since 29 October 2004) and by Prime Minister Hun Sen (since 14 January 1985), Cambodia is divided in 23 provinces and one municipality. Being one of the poorest countries in Asia, more than 50% of the government budget comes from donor assistance – the Cambodian government is working with bilateral and multilateral donors, including the Asian Development Bank, the World Bank and IMF.

cambodia_populationCambodia has a 2017 population of 16,245,729 people and a density of 211.8 per square mile, as stated by a July, 2013 estimate provided by CIA World Factbook. For Cambodia, the estimate was calculated  considering the effects of excess mortality due to AIDS, which can result in lower life expectancy, higher infant mortality, higher death rates, lower population growth rates, and changes in the distribution of population by age and sex than would otherwise be expected. The last census took place in 2008 and indicated a total population of 13,388,910 people. A 2013 estimate indicates a population growth rate of 1.67%, making Cambodia the 71st country in the world by growth of the human population, while birthrate is 24.88 births/1,000 population. Life expectancy at birth is of 63.41 years – rank 179 in the world -, 61.01 years for males and 65.93 years for females. Sex ratio at birth is 1.05 male(s) per female and of total population is of 0.94 males(s) per female. According to a 2009 estimate, 3,100 people from Cambodia died of HIV/AIDS. The degree of being infected with major food, waterborne, and vector borne diseases is very high. The country’s urban population is projected to double until 2030, while the rural population will grow only by 14.2%. By the end of the projection period, urban areas will be experiencing an annual growth of 2.22% while rural areas of only 0.25%. In general, the growth in urban areas will be determined mainly by migration.

2018 Economy in Cambodia

cambodia_economyReported to CIA World Factbook, Cambodia is one of the poorest countries in Asia and long-term economic development remains a daunting challenge because it is inhibited by endemic corruption, limited educational opportunities, high income inequality, and poor job prospects. Based on agriculture, industry and services, Cambodia’s GDP is $36.64 billion as of 2012 while GDP per capita is rated at $2,400. Approximately 4 million people live on less than $1.25 per day and 37% of Cambodian children under the age of 5 suffer from chronic malnutrition. Over the next decade, the major economic challenge for Cambodia will be fashioning an economic environment in which the private sector can create enough jobs to handle its demographic imbalance.
