Core Viewpoint - The article highlights a significant demographic crisis in China, predicting a drastic population decline from 1.4 billion to 580 million in the next 50 years, emphasizing the urgency of addressing this issue [2][18]. Group 1: Population Decline - The prediction by economist Lang Xianping indicates a potential population drop to 580 million in 50 years if current birth rates continue [18]. - The birth rate has been declining sharply, with newborns falling from 1,846,000 in 2016 to 902,000 in 2023, marking a significant decrease [10][14]. - In 2024, the projected number of newborns is 954,000, while deaths are expected to reach 1,093,000, resulting in a net population decrease of 139,000 [16]. Group 2: Aging Population - The elderly population (60 years and above) reached 290 million in 2023, accounting for 21.1% of the total population, indicating a rapidly aging society [20]. - By 2031, it is projected that one in five individuals will be 65 years or older, leading to a significant increase in the old-age dependency ratio [22]. - The old-age dependency ratio is expected to rise from 22.5% in 2023 to 48.8% by 2050, indicating a growing burden on the working-age population [24]. Group 3: Reasons for Low Birth Rates - Young couples cite the high cost of raising children as a primary reason for not having more kids, with expenses for a single child reaching tens of thousands of yuan [29][31]. - The financial burden of housing loans and living expenses leaves little room for additional children, making it increasingly difficult for young families to consider expanding [31]. - The impact of childbirth on women's careers also deters many from having children, as societal pressures and workplace biases create additional challenges [33].

Core Viewpoint - Japan's population is experiencing a significant decline, reaching a historic low, which raises concerns about the country's demographic future and potential economic implications [1][2][4].

Group 4: Existing Support Measures - Japan has implemented various support measures for families, including one-time childbirth subsidies of 500,000 yen, monthly allowances for children, and free education from preschool to high school [14]. - Despite these efforts, the birth rate remains low, indicating that financial incentives alone may not be sufficient to encourage higher birth rates [14][15]. Group 5: Societal Implications - The ongoing economic challenges, such as high living costs and job instability, contribute to the reluctance of young people to marry and have children, with many still living with their parents [15][19]. - The discussion around the "single tax" reflects broader societal issues, including the need for stable employment, affordable housing, and gender equality in the workplace to create a conducive environment for family growth [19][20].
