Aging of China
China's population is aging faster than almost all other countries in modern history. In 2050, the proportion of Chinese over retirement age will become 39 percent of the total population. China is rapidly aging at an earlier stage of its development than other countries. Current demographic trends could hinder economic growth and create challenging social problems in China. In 1979, the Chinese government established a controversial one-child policy aimed at curbing the high fertility rate. With economic development, the provision of social services, and improved welfare conditions, life expectancy in China has also increased. These  two factors have directly contributed to China's aging population, which has significant ramifications on China's society, politics, and economy. In October 2015, a two-child policy was introduced in an attempt to deal with the aging problem. In May 2021, the Chinese government introduced the three-child policy in a further attempt to address the issue. Overview. From 1950 to 2020, the total fertility rate in China dropped from 6.11 to 1.3 births per woman while the mortality rate also decreased, from 22.2 to 7.1 per 1,000 people. Life expectancy rose from 44.6 to 77.47 years during this  period and is expected to reach about 80 years in 2050. In 2018, 249.49 million people over 60 years old constituted 17.9 percent of the total population. In the rural area, the percentage of the elderly population is slightly higher than that in the city. The fastest aging region is Western China. In October 2015, a two-child policy was introduced by the Chinese government in an attempt to increase the fertility rate. Causes. China's aging population is caused by a low birth rate together with prolonged human life expectancy. Low fertility rates. One-child policy. In order to  suppress excessive population growth, the one-child policy was introduced in 1979. The enforcement methods include financial penalties, widespread use of various contraceptive methods, as well as more severe forced abortion and sterilization. As a result, birth rates and population growth rates have drastically decreased. Reproductive health of couples. With economic growth and social development, increasing smoking, alcohol use, unhealthy diets, and psychological stress have an effect on lowering the fertility rates of couples. Surging pollution in China also has an impact on male sperm count, which has been declining since the 1970s. At the Chinese University of Hong Kong , a team of scientists studied the sperms from approximately 6,500 men and found a "strong correlation" between high levels of air pollution and "abnormal sperm shape". Researchers point out that many particulate matter components are associated with sperm damage in experimental studies. Exposure to air pollutants may cause free radicals damage which adversely alters DNAs and cellular processes in the human body. These conditions may be associated with a significant number of infertile couples, lowering the fertility rate. Cultural impact. China's sex ratio is the most skewed in the world. The country's ratio of males to females is  skewed 3% to 4% higher towards males. In the traditional, patriarchal society, many Chinese people believed that men were more important than women. This mindset has continued to be prevalent in modern China, especially in rural areas, resulting in high female fetal abortion rates and even female infanticide. The imbalance in sex ratio has led to a decrease in marriage rates and birth rates in China. Extension of human life span. The improvements in social welfare and the medical system have prolonged people's life span. Since 1949, the general health of the Chinese people has greatly improved, and the  life expectancy has increased by about 30 years, from 44.6 to 75.3 years from 1950 to 2015. It is expected to reach approximately 80 years in 2050. The minimum income security in rural areas has been expanded and is covering more than 50 million residents in poor areas. The Chinese government has unified the welfare systems of urban and rural migrants, and the pension system covers nearly 700 million people. Despite the improvement of China's social welfare system, there are still huge inequalities in health between urban and rural areas. Compared with urban peers, the number of medical service  providers for rural residents is significantly reduced, and the utilization rate of facilities is low, resulting in their poor health. Since the late 1990s, three new medical insurance systems have been established by the government to provide more health care services. In 2009, urban and rural health insurance reforms achieved greater coverage. More advanced medical techniques have reduced the prevalence of diseases and increased survival. Impacts. The demographic trend of aging population has social, political and economic ramifications in China. The growth of the elderly population has increased the dependency ratio and the prevalence of many chronic diseases. Aging society  has also brought about changes in public policy. The weakening of the labor force has negative impacts on China's economic growth and development, which was originally driven by the labor market. Social. Rapid aging could create challenging social problems and increase the risk of social instability in China. Due to the lower fertility rate and extension of the human life span, the population in China is aging faster than almost all other countries. In 2050, the proportion of Chinese over retirement age will become 39 percent of the total population. At that time, its dependency ratio will rise to  69.7%, almost twice as high as that in 2015, which was about 36.6%. The higher dependency ratio is associated with the greater pressure placed on those who are working to support the rest of the population. Even if the Chinese government provides part of the financial support for the elderly through social welfare, such as pensions and public welfare homes, there are still many elderly people in China who are unable to be taken care of. In 2015, there were, on average, 27 beds per 1,000 elderly in nursing homes in China, far fewer than those in the United States  or Germany. The aging population in China has increased the incidence and types of chronic diseases. Chronic diseases include four basic types: cardiovascular diseases, cancer, respiratory diseases, and diabetes. There are nearly 300 million chronic patients in China, half of whom are over 65 years old. During aging, many cellular and molecular events break down and eventually lead to a variety of chronic diseases, such as coronary heart diseases (CHD). The number of CHD incidents and deaths in China will increase dramatically from 2010 to 2029; among Chinese adults aged 35–84, a 64% increase in CHD occurrences is predicted between  2020 and 2029. Political. A large number of the elderly population has increased the pressure on the Chinese government to allocate the pensions and make social welfare more accessible. The lack of conventional financial infrastructure and the extent of the aging population make it difficult for China to provide a holistic solution. Even at an economic growth rate of 8 percent, pension spending is growing much faster at a rate of 15 percent per year. Pension expenditure increased by 11.6% in 2016, reaching 2.58 trillion yuan, with a shortfall of 429.1 billion yuan, requiring government subsidies. Since the establishment of  the pension system, China has been paying the income of retirees with the contribution of the working population. As more people retire and fewer people enter the labor market, the gap between income and expenditure will continue to widen. China's Working Committee on Ageing suggested that the inclusion of improved care services for the elderly in the national development road-map would be a key measure for the top leadership to cope with population aging. The elderly care service market provides more opportunities for private capital and non-governmental organizations so that the elderly can have more service choices . Geopolitical. China's aging population could hinder economic growth, create challenging social problems, and limit its capabilities to act as a new global hegemon. Ryan Hass, a senior fellow in foreign policy at the Brookings Institution, said, "China is at risk of growing old before it grows rich, becoming a graying society with degrading economic fundamentals that impede growth." He went on to say, "The working-age population is already shrinking; by 2050, China will go from having eight workers per retiree now to two workers per retiree. Moreover, it has already squeezed out most of the large productivity gains  that come with a population becoming more educated and urban and adopting technologies to make manufacturing more efficient." Nicholas Eberstadt, an economist and demographic expert at the American Enterprise Institute, said that current demographic trends will overwhelm China's economy and geopolitics, making its rise much more uncertain. He said, "The age of heroic economic growth is over." Brendan O'Reilly, a guest expert at Geopolitical Intelligence Services, wrote, "A dark scenario of demographic decline sparking a negative feedback loop of economic crisis, political instability, emigration and further decreased fertility is very real for China". Economic. Labor force. Since economic expansion  is the sum of input factor growth and productivity growth, it will require a substantial increase in labor productivity to sustain the same top-line growth as the population ages. China's aging population has led to a contraction of the labor force that induces a slowing economic growth. In 2017, China's total working-age population (aged between 15 and 64) was 988.3 million, which dropped by a large margin of 70 million from the end of 2016. China is urged to raise the legal age of retirement to cope with the problem of a reduced labour force. In  2016, the Chinese government announced plans to gradually raise the retirement age from 50 years old to over 60 years old. It may expand productivity and improve the sustainability of national pension accounts by improving the level of education and skills of Chinese workers to make up for the gap from the decreasing proportion of the working-age population. In order to improve the quality of the labor force, the number of university enrollment has increased by seven times since 1999 in China. Aging in China has affected women's labor force participation to a certain extent. A large proportion  of grandparents in China provide the free services of raising grandchildren for their children. This constitutes a main reason why women decide to stay in the labor market. China has a relatively high female labor force participation rate of 61.5%. Allocation of government funds. An increase in the number of retirees and a decrease in the number of taxpayers will affect the government's allocation of funds. The expansion of the elderly ratio forces the government to support them by providing pensions and expanding social welfare, which will affect the government budget. China's pension funds accounted for nearly 70 % of China's social security income in 2017. Without subsidies from the central government, many local pension funds will run into a deficit, of which the total is expected to rise from 234 billion yuan to 534 billion yuan in 2022. Government policies. In order to alleviate the population aging in China, the Chinese government has tried to relax the birth controls to increase the birth rate. Two-child policy. In October 2015, the two-child policy was introduced to replace the one-child policy. China has been taking gradual measures to eliminate the one-child policy. In 2009, if  both parents were only children, they were allowed to have two children. In 2014, most provinces in China further relaxed their policies, allowing families to have two children if one of the parents was an only child. However, since the implementation of the two-child policy, there has been no significant improvement in China's population aging. It is expected that the effect of the policy will not be significant until two decades later. After the relaxation of the one-child policy, 17.9 million babies were born in 2016, an increase of 1.3 million over the previous year, but only  half of what was expected. In 2017, the birth rate fell to 17.2 million, far below the official forecast of more than 20 million. Three-child policy. In May 2021, the Chinese government introduced the three-child policy in a further attempt to address the issue.
