#Fertilityrate

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.

A provocative study from Shizuoka University questions whether today’s fertility level is high enough to sustain human populations over the long term. It argues that a global average of 2.1 births per woman—the traditional replacement rate—may not guarantee stability. Instead, the research suggests a higher threshold of about 2.7 births per woman could be necessary. The findings matter for Thailand, where current fertility sits well below that target.

Historically, experts worried about overpopulation as populations exploded—from under 3 billion in 1960 to over 8 billion today. Public health campaigns, contraception access, and shifting social norms reduced fertility dramatically. By 2023, the world’s average had dropped to around 2.3 births per woman. In many Asian countries, including Thailand, this rapid demographic transition was seen as a development success.

Kylie Kelce, wife of NFL star Jason Kelce, has captured the hearts and attention of fans and parenting communities in Thailand and beyond after sharing a deeply personal story about her decision to grow her family. In a candid interview with People magazine, Kylie described the emotional moment she realized she wanted to have another baby, reminding many readers of the complex mix of emotion, practicality, and love that goes into making family planning decisions. While her story is deeply personal, it highlights broader trends and research into what motivates people—particularly women—to consider having more children, a topic that carries significant cultural resonance in Thailand as birth rates continue to decline [source: People Magazine].
