长期被新生人口危机困扰的韩国似乎迎来了变化的希望。继去年总和生育率（平均每名育龄妇女一 生所生育子女数）时隔9年首次出现小幅回升之后，今年1月至7月韩国共有147804名婴儿出生，比去年 同期增长了7.2%，这是1981年以来的最高增长率，同时也是自2015年以来1月至7月期间新生儿数量首 次出现同比增长。此外，出生人口已实现连续13个月同比增长。对应的7月份总和生育率达到了0.8。按 照这种趋势，估计到今年年底韩国出生人口可实现连续两年的增长。 新生人口持续减少 虽然目前发达国家的人口出生率都在下降，但韩国的下降起始时间更早，至今已经延续了60多年， 并且年复一年地刷新最低纪录。从长期来看，韩国新生儿出生率的最低点出现在2023年。这一年，韩国 新生儿数量仅为23万人，不到上世纪70年代高峰期的三分之一。首都首尔的生育率更是低至0.59，成为 全球生育率最低的主要城市之一。同时，当年韩国0.72的总和生育率也在世界所有国家中处于最低水 平。此外，虽然2024年韩国生育率升至0.75，但依然未能摆脱全球最低的位置，不仅与维持人口基本稳 定所需的2.1相差甚远，还大大低于超低生育率（≤1.3）的国际标准。 韩国 ...

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 - The introduction of a "single tax" in Japan has sparked significant public backlash, as it is perceived as an unfair burden on single individuals to support families with children, amidst a declining birth rate crisis [1][3][7]. Group 1: Tax Implementation - Starting from April 2026, the Japanese government plans to impose an annual tax ranging from 2,400 yen to 12,000 yen (approximately 120 to 600 yuan) to fund subsidies for families with children, labeled as "child and parenting support funds" [3][10]. - The tax will increase gradually, reaching 19,800 yen by 2028 for higher income brackets [10][11]. Group 2: Public Reaction - There is widespread discontent among the public, particularly among younger individuals, with over 60% opposing the tax, viewing it as a financial strain amid rising living costs [12][13]. - Many individuals express frustration over being forced to financially support others' choices regarding family planning, especially when they are already facing economic difficulties [12][17].

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].

Core Viewpoint - Japan is facing a severe population crisis, prompting the government to implement a new "Child and Childcare Support Fund" starting April 2026, which will levy an annual tax ranging from 2,400 to 12,000 yen (approximately 120 to 600 RMB) to subsidize families with children [3][5].

Group 2: Government Response and Historical Context - The new tax is perceived as a "universal fertility tax" rather than a "single tax," as it applies to all individuals who pay health insurance, regardless of whether they have children [5][6]. - Historically, various nations have implemented similar taxes on single individuals, including ancient Greece and Rome, as well as the Soviet Union, which had a "childless tax" until 1992 [6][7]. Group 3: Challenges in Stimulating Birth Rates - Despite over 66 trillion yen (approximately 3 trillion RMB) invested in fertility incentives over the past 30 years, Japan's birth rate has not improved significantly [19][24]. - Current support includes a one-time childbirth subsidy of 500,000 yen (about 25,000 RMB) and annual childcare subsidies of 120,000 to 180,000 yen for children aged 0-3 [20][21]. - The societal trend of declining marriage and increasing single-person households complicates the situation, with predictions indicating that by 2035, half of the population aged 15 and above may be single [17][26].

Group 1 - The Japanese government plans to implement a "Child Future Strategy" starting in 2026, requiring all citizens and businesses to pay a "support fund" through health insurance surcharges, with monthly contributions expected to range from 250 to 700 yen by 2028 [3] - The initiative aims to address Japan's declining birth rate, which is projected to fall below 700,000 newborns in 2024, with a birth rate of 1.2, significantly below the replacement level of 2.1 [5] - The strategy includes expanding child allowances and providing educational subsidies to encourage marriage and childbirth among young people [5] Group 2 - In contrast, China faces similar demographic challenges, with a population decrease of 2.08 million in 2023 and a natural growth rate of -0.15‰, alongside a declining birth rate of 9.02 million [5] - The Chinese single population exceeds 240 million, with over 77 million living alone, indicating a significant economic burden on this demographic, which could be exacerbated by a potential "single tax" [6] - China has implemented various measures to encourage childbirth, including the promotion of two-child and three-child policies, extended parental leave, and increased investment in childcare services [7]

Group 1 - Japan's newborn birth rate has fallen below 700,000, with a total fertility rate dropping to below 1.2, breaking historical records. It is projected that by 2070, Japan's population may decrease from 120 million to 87 million [2][3] - The Japanese government is implementing a "Child and Childcare Support Fund" system starting in April 2026, which will impose monthly fees on individuals aged 20 and above without children and earning over 2 million yen annually, including foreign residents. The fees will range from 200 to 1,000 yen per month, with a maximum of 1,650 yen [3][4] - This initiative has been interpreted by the public as a "single tax," leading to significant controversy and debate among citizens regarding the fairness of taxing individuals for not having children [7][12] Group 2 - Concerns are raised that if the trend of declining birth rates continues, Japan's population could drop to 50 million by 2100, predominantly consisting of elderly individuals. This demographic issue is echoed in other countries, such as China, where the elderly population is also increasing significantly [13]
