Fact check: South Korea is in trouble in terms of birth rate. In several decades they will completely disappear unless what?

Checked on July 28, 2025

1. Summary of the results

South Korea is indeed facing a severe demographic crisis with the world's lowest fertility rate at 0.75, far below the 2.1 replacement level needed to maintain population stability [1] [2]. The situation is so dire that projections suggest the population could plummet to 15% of its current level over the next 100 years [3], with some studies indicating the population could drop to just 7.53 million by 2125 - an 85% decline [4].

However, there are recent positive developments. For the first time in nine years, South Korea's birth rate rose in 2024 [2], with a 6.9% growth rate in newborns during the January-May period [1]. Despite this improvement, the fertility rate remains critically low.

The underlying causes are multifaceted, including high child-rearing costs, long work hours, and competitive societal pressures [5]. Interestingly, fertility clinics are experiencing a boom with a 50% increase in treatments between 2018 and 2022 [6], suggesting people want children but face significant barriers.

2. Missing context/alternative viewpoints

The original question implies inevitable population collapse without specifying solutions, but the analyses reveal several important missing contexts:

  • Government intervention is already underway: South Korea's government has set a target to increase the fertility rate to 1.0 by 2030 through policy efforts and corporate incentives for parenthood [2].
  • Policy effectiveness debate: There's significant disagreement about whether government pronatalist policies can effectively address the crisis without tackling underlying social and economic issues [5]. Some sources suggest that simply providing financial incentives may not be sufficient.
  • Recent positive trends: The question focuses on doom scenarios but omits the recent uptick in births and increased fertility treatment usage, which could indicate changing attitudes or policy effectiveness [1] [2].
  • Specific policy recommendations: Sources mention the need for expanding support to reduce childbirth and child-rearing burdens and urgent policy directions [4], but these concrete solutions are absent from the original framing.

3. Potential misinformation/bias in the original statement

The original statement contains several problematic elements:

  • Catastrophic framing: The phrase "completely disappear" is alarmist and not supported by the data. Even the most pessimistic projections show an 85% population decline, not complete disappearance [4].
  • Deterministic language: The statement implies inevitability ("unless what?") while ignoring that policy interventions are already showing some positive results [2] [1].
  • Oversimplification: The question suggests there's a single solution when the analyses reveal this is a complex crisis requiring multifaceted approaches addressing economic, social, and cultural factors [5].
  • Temporal bias: The statement ignores recent positive developments, potentially reflecting outdated information that doesn't account for the first birth rate increase in nine years [2].

The framing benefits those who profit from crisis narratives or demographic panic, while potentially undermining confidence in existing policy efforts that are beginning to show results.
