#PopulationDecline

The world’s rapidly declining birth rates have ignited a cultural, political, and economic debate that has reached new prominence in 2025. Concerns surrounding fertility decline, its impacts on social structures, and emerging “pronatalist” movements—those actively promoting higher birth rates—have transitioned from quieter academic discussions to mainstream headlines in Thailand and beyond. The issue isn’t simply statistical: it touches on the future of economies, generational care, cultural norms, and even environmental discussions, prompting stakeholders across the globe to rethink whether “more babies” is the solution to looming demographic challenges.

A dramatic new wave of research suggests global fertility rates are in unprecedented decline, with millions of people around the world struggling to have the number of children they desire—often not because of changing attitudes, but because of mounting social and economic obstacles. Recent studies—including a large survey conducted by the United Nations Population Fund (UNFPA)—show that in both high- and middle-income countries, including Thailand, the costs of parenthood, job insecurity, insufficient welfare support, environmental anxieties, and evolving cultural priorities are driving birth rates to historic lows Time, BBC, Al Jazeera.

Sangamon County, located in central Illinois, is grappling with its first population decline in two centuries—a development that has community leaders sounding the alarm and seeking innovative solutions to reverse the trend. According to recent remarks by the County Board Chair at a chamber of commerce luncheon, the region—best known as the seat of the state capital Springfield—has lost approximately 1,000 residents over the past decade, a decline that is especially pronounced among young people and working-age adults (newschannel20.com).

A groundbreaking new study is challenging longstanding demographic wisdom by asserting that humanity’s current fertility rate is now too low to guarantee survival—even if average births per woman meet the historical “replacement” level. The research, led by a Japanese scientist and published in the journal PLOS One, argues that the global average of 2.1 children per woman simply isn’t enough. Instead, it suggests that a fertility rate of 2.7 is the true mark required to ensure humanity’s long-term prospects, a conclusion that carries serious implications for countries like Thailand, where the fertility rate is well below these thresholds.
