Band 8 model answer

Across many industrialised nations, the single-child family has shifted from an unusual arrangement to an increasingly common one. Examining what is driving this change, and whether it represents a positive or negative development for individuals and societies, reveals a complex picture.

Economic pressure is the most frequently cited cause. In cities where housing costs have escalated sharply over recent decades, raising more than one child can strain household finances to a degree that many couples are unwilling or unable to sustain. Career ambition among women, facilitated by greater workplace equality but also driven by economic necessity, means that more parents defer childbearing until later in life, reducing the window available for multiple pregnancies. In some countries, cultural narratives around self-actualisation and lifestyle flexibility have also shifted parental expectations, with couples prioritising personal fulfilment alongside, or even above, family formation.

The implications of this trend divide opinion. For the individual child, concentrated parental attention and resources can translate into educational advantages, richer extracurricular opportunities and greater financial security. From a societal perspective in countries with overpopulation pressures, fewer children per family eases demand on housing, infrastructure and environmental resources.

However, the long-term social consequences are concerning. Ageing populations with a shrinking ratio of working-age adults to retirees place unsustainable pressure on pension and healthcare systems, as several European countries are already discovering. For the children themselves, growing up without siblings can limit the development of negotiation, conflict-resolution and sharing skills that sibling relationships naturally cultivate. Extended families become smaller across generations, reducing the informal support networks that buffer individuals against hardship.

On balance, while individuals are entirely free to make this choice, the broader societal trend towards single-child families is mildly negative, primarily because of the demographic and social-cohesion pressures it generates.
