Core Viewpoint - The article discusses the significant decline in China's birth rate and its implications for the country's demographic structure and global population share, predicting that the proportion of newborns in China may fall below 7% of the global total by 2025 [4][10][45]. Group 1: Birth Rate Decline - China's newborn population is projected to be around 8.71 million in 2025, marking a decrease in its share of global newborns to below 7% [4][10]. - The proportion of newborns in China has drastically decreased from nearly 25% in the early years of the People's Republic to about 17% today, and is expected to drop further [7][10]. - Historical data shows that the peak of China's newborn population share was 27.3% in 1964, which has steadily declined over the decades [14][10]. Group 2: Population Structure Changes - As of 2023, it is estimated that India's population has surpassed China's, making China the second most populous country [11]. - The total fertility rate in China has fallen significantly, with estimates showing it dropped to around 1.15 in 2021 and below 1.1 since 2022, which is lower than Japan's rate of 1.3 [22][24]. - Predictions indicate that if the current fertility rate persists, China's population could decrease to 1.374 billion by 2030 and further to 1.23 billion by 2050 [26][28]. Group 3: Economic and Social Implications - The high cost of raising children in China is a significant factor contributing to the declining birth rate, with average costs for raising a child from 0-17 years estimated at 630,000 yuan in urban areas [33]. - The article suggests that a declining population may lead to improved living standards and reduced environmental pressures, as fewer people could mean less resource consumption [46][47]. - Despite the potential challenges of a shrinking workforce, advancements in technology, such as AI and robotics, may provide solutions to labor shortages in the future [47].
