Cambodia, located in Southeast Asia, has undergone remarkable demographic changes over the past 70 years. From a population of just 4.4 million in 1950, the country has grown to 17.6 million in 2024. Projections indicate that Cambodia’s population will continue to rise throughout the 21st century, peaking around 23.3 million by 2075, before experiencing a gradual decline to 22.7 million by 2100.
Cambodia’s Historical Population Growth (1950–2024)
Cambodia’s population increased steadily during the mid-20th century:
- 1950: 4.4 million
- 1960: 5.5 million
- 1970: 6.6 million
- 1980: 5.2 million (decline due to conflict and instability)
- 1990: 7.4 million
The Khmer Rouge era (1975–1979) had a devastating demographic impact, as population growth stalled and mortality spiked.
Rapid Growth and Recovery (1990–2024)
From the 1990s onward, Cambodia experienced sustained recovery and growth:
- 2000: 12.5 million
- 2010: 14.5 million
- 2020: 16.7 million
- 2024: 17.6 million
This growth was fueled by stabilization, economic recovery, and improvements in healthcare, leading to falling mortality rates and higher life expectancy.
Cambodia’s Future Population Projections (2025–2100)
Cambodia’s population is expected to expand further before plateauing and eventually declining:
- 2030: 18.8 million
- 2050: 21.9 million
- 2075: 23.3 million (projected peak)
- 2100: 22.7 million
Unlike some neighboring countries, Cambodia is projected to maintain relatively strong growth through mid-century, with stabilization after 2075.
