Band 9 Sample Answer — 290 words

A marked demographic shift towards single-person households — particularly among adults in their twenties and thirties — has become apparent across many developed nations. While the freedom of independent living has clear appeal, this trend generates significant social and economic problems that require attention from both individuals and governments.

The most serious problem associated with solo living is its impact on mental health. Social isolation, even when voluntary, correlates strongly with elevated rates of depression, anxiety, and loneliness — conditions that impose substantial costs on healthcare systems and reduce individual productivity. Compounding this, young people living alone often face disproportionate financial pressure: single occupancy drives up per-capita housing costs, energy bills, and daily expenditure, placing added strain on a demographic already burdened by student debt and stagnant entry-level wages.

Addressing these challenges requires a combination of architectural, policy, and community-based solutions. At the design level, the expansion of co-living spaces — private rooms within shared residences equipped with communal kitchens and social areas — offers a practical compromise between independence and regular human interaction. Such models already operate successfully in cities including Tokyo, Amsterdam, and London, reducing both living costs and social isolation simultaneously.

Governments can further mitigate the problem by funding community hubs in residential areas and by incentivising purpose-built rental housing targeted at single adults. On a more individual level, employers have a meaningful role: flexible working arrangements that facilitate genuine in-person social connection — rather than isolation-amplifying remote work — can significantly reduce the loneliness that solo living produces.

In conclusion, while single-person living reflects legitimate lifestyle choices, concerted efforts across architecture, housing policy, and employment practice are needed to counterbalance its social and financial costs.
