Seoul:South Korea is confronting significant demographic changes as the nation's birth rate continues to decline and the population ages, necessitating urgent reforms in education and public spending. Projections indicate that first-grade enrollment will fall below 300,000 by the 2027 academic year, marking a significant decrease from past figures.

According to Yonhap News Agency, the 2020 birth cohort consisted of only 272,337 children, which is markedly less than the 1.05 million students who enrolled in elementary school during the peak year of 1968. This decline in enrollment is expected to continue, with numbers dropping below 400,000 in 2024 and further decreases projected through 2030.

The implications of this demographic shift extend beyond education. South Korea's old-age dependency ratio is projected to increase significantly, reaching 68.4 by 2045 and 103.3 by 2070, the highest among OECD countries. This means that a smaller working-age population will need to support a growing elderly demographic, with spending on elderly programs expected to rise substantially from 2026 to 2030.

The current formula for education financing, which is tied to domestic tax revenue, results in increased funding despite decreasing student numbers. From 2016 to 2025, per-student funding nearly doubled, a trend that highlights the need for a revised funding approach that could also support higher education and adult retraining.

The demographic changes also necessitate regional planning for school networks, as blanket school closures could lead to inefficiencies. Moreover, addressing underlying issues such as housing costs and career penalties is crucial for shaping family decisions, as cash support alone is insufficient.

Efforts to maintain workforce participation are vital, with a focus on creating opportunities for older adults and reducing workplace penalties for women. Enhancing productivity through flexible work arrangements and midcareer training is essential as the workforce shrinks.

Finally, the demographic adjustment requires a thorough evaluation of public spending, eliminating redundant programs and coordinating health and care services to optimize costs. The government has the opportunity to reshape institutions to better serve the future population, despite the challenges posed by the current demographic trajectory.
