North Korean famine
With the exception of a small Chinese community and a few ethnic Japanese, North Korea's people are ethnically homogeneous. Demographic experts in the 20th century estimated that the population would grow to 25.5 million by 2000 and 28 million by 2010, but this increase never occurred due to the North Korean famine. It began in 1995, lasted for three years and resulted in the deaths of between 240,000 and 420,000 North Koreans.
