Population reduction, also known as depopulation, refers to a decrease in the number of individuals in a population, which can occur due to various factors such as natural disasters, diseases, wars, famines, or government policies. In Hebrew, this term can be translated as הפחתת אוכלוסייה (Hafchat Eiluta). In other languages, it may be referred to as Reducción de la población in Spanish, Réduction de la population in French, and Bevölkerungsreduktion in German. Population reduction can be a natural process or a result of human intervention, and it can have significant social, economic, and environmental impacts. Historically, population reduction has been observed in various forms, including the Black Death in the 14th century, which significantly reduced the population of Europe, and the Holocaust during World War II, which resulted in the systematic murder of six million Jews by the Nazi regime. In contemporary contexts, population reduction can also refer to policies aimed at controlling population growth, such as China's former one-child policy.
