Higher Incomes, Fewer Children

African nations with high fertility rates today often appear ‘late’ when compared to their Western counterparts. Yet the demographic transition theory anticipates that fertility declines as prosperity grows. Botswana exemplifies this pattern strikingly. Once among the world's poorest nations, with a GDP per capita of roughly $70 in the 1960s and a fertility rate of 6.9 children per woman in 1970, almost overnight Botswana found its soil contained diamonds, the supply of which it wisely managed. By 2023, its GDP per capita rose to approximately $7,700, placing it among Africa's middle-income countries. Subsequently, fertility rates decreased markedly, dropping to 2.8 children per woman by 2023.

Humans have thus notably diverged from animal instincts, where improved conditions invariably lead to increased reproduction. Urban life and technological progress have recalibrated human desires, subordinating biological imperatives to cultural preferences.

Is There New Hope?

For decades, the decline appeared inexorable. Factors such as one’s prime years for reproduction being spent in higher education, particularly by women, compound demographic pressures. Attaining a university degree, often indispensable for securing lucrative employment, delays family formation significantly. 

According to Eurostat, in 2021, the average age for European women’s first marriage was 31.1 years, and for men, 33.7 years. Increasingly, marriage no longer precedes parenthood, and the average age for a woman bearing her first child stands at 29.7. 

In addition, women are most fertile between the ages of 20 and 25. Postponing motherhood past thirty involves inherent risks and complications, deepening the divide between career ambitions and family aspirations. Science, although advancing rapidly, thus remains constrained by these biological realities.

Nonetheless, the authors of ‘Not So Weird After All: The Changing Relationship Between Status and Fertility’ provide unexpected insights. Having analysed fertility relative to wealth and education in Sweden, they reveal a paradoxical trend: individuals with higher incomes and education have more children than their less affluent counterparts. Even women with extensive education increasingly value family, challenging conventional assumptions that prolonged and higher education diminishes family size.

State intervention plays a crucial role in Sweden's demographic dynamics. Generous parental leave policies, offering eight months per parent at 80% salary, mitigate fears that children compromise economic stability. Thus, robust state-supported family policies demonstrate tangible successes, suggesting investments in family welfare are strategic rather than merely fiscal.

A Path Forward or an Irreversible Decline?

The global demographic trajectory appears fractured. From overcrowded villages in Somalia to deserted kindergartens in Singapore, affluence generally correlates with smaller families. Europe's demographic crisis—characterised by persistently low fertility and an ageing population—faces both cultural and biological hurdles deterring parenthood. 

Yet Sweden’s experience provides a provocative counter-narrative, demonstrating that higher education and financial success can accompany increased fertility. Swedish outcomes reveal how enlightened policies could disrupt traditional narratives about the socio-economic elite's aversion to parenthood.

Ultimately, the Swedish example underscores that proactive governmental policy is a strategic imperative to confront demographic stagnation. Whether other nations heed this lesson in time remains an open and urgent question, crucially determining whether demographic decline becomes irrevocable or if fertility can sustainably rebalance across divergent cultures

Statement

From Niger's vibrant, strained maternity wards to Seoul’s eerily silent nurseries, global fertility has fractured along the fault lines of prosperity. Wealth, education, and delayed adulthood have suppressed fertility in affluent nations, turning parenthood from an aspiration into a burden. Europe’s demographic slide, seemingly irreversible, deepens. Yet Sweden emerges as an anomaly: robust family policies demonstrate prosperity and education needn't suppress fertility. Sweden’s approach is a strategic investment to counter demographic stagnation. The lesson is stark: Without intentional state intervention, declining fertility risks becoming entrenched, reshaping societies in fundamental ways.
