Population ageing refers to the phenomenon of population distribution biased towards aging. The increase in life expectancy has led to an increase in the elderly population, and the declining birthrate has led to a decrease in the juvenile and working population. Most of the developed countries and some developed countries in the world have obvious phenomena of population ageing.
Population ageing has a major impact on the economy. As the proportion of the workforce has fallen, overall productivity has gradually declined. The originally prepared welfare pension system due to the lower payment amount for the backwards, but the required expenditure gradually rises, the compensation rate will also decrease, and the sustainability of the pension system will also be challenged. Some people believe that advances in technology and automation can reduce the impact of an aging population, but the proportion of the world’s elderly population will continue to rise in the foreseeable future. This is a social problem that has never been faced by human history.
