Band 8.5 model answer: opinion (agree or disagree)

A band 8.5 model answer to a real IELTS Writing Task 2 question, with the paragraph plan that fits it. Aim for 250 to 290 words in 40 minutes.

The question

In many countries, an increasing number of couples are choosing to have pets instead of children. What are the reasons for this trend, and what effects does it have on society?

Your 4-paragraph plan

Introduction (40-50 words). Paraphrase the statement and give your clear opinion in one sentence.
Body paragraph 1 (80-100 words). First reason you hold this view, with one specific example.
Body paragraph 2 (80-100 words). Second reason, or address the strongest point on the other side and explain why your view still holds.
Conclusion (40-50 words). Restate your opinion in fresh words and summarise your two reasons.

The trap in this question type

Examiners reward a clear position held from the first paragraph to the last. Do not sit on the fence, and do not switch sides halfway.

A generation ago, a Manila office worker without children by the age of 35 would have faced constant questioning from relatives; today she is more likely to be asked about her dog's vaccination schedule than her fertility plans. Behind this quiet substitution lie clear financial and career pressures, and the trend is now visible enough to be reshaping labour markets and social habits well beyond the household. The reasons are largely financial and professional. Raising a child in Singapore is estimated to cost over 200,000 dollars from birth to university, covering tuition, tutoring and housing in a notoriously expensive property market, whereas a dog or cat might cost a few thousand dollars a year in food and veterinary bills. Career timing compounds this calculation: a woman pursuing a partnership track at a law firm is acutely aware that a period of parental leave can stall promotion for years, so a pet becomes the lower-risk substitute for domestic companionship, one that asks for a daily walk rather than a decade of reduced earning power. One consequence of this shift is a shrinking and ageing workforce. South Korea's fertility rate has fallen below one child per woman, and factories in cities such as Busan already report difficulty filling apprenticeships that once drew large cohorts of school leavers; as the working-age population contracts, pension systems built on a growing base of contributors face a structural funding gap that no amount of pet spending can offset. Governments have responded with cash incentives for childbirth, largely without success, which suggests the underlying calculation about cost and career risk is not easily reversed by subsidy alone. A second, more favourable consequence is the emergence of entire industries built around animal companionship. Japan's market for pet insurance, gourmet pet food and even pet funerals has grown into a sizeable industry, creating jobs in veterinary care and pet-friendly hospitality that barely existed a generation ago. Beyond commerce, a dog often gives an otherwise isolated elderly person a reason to walk daily and exchange a few words with neighbours, a modest but reliable source of the casual social contact that sustains mental health in later life. Overall, the pivot from children to pets reflects a rational response to economic strain rather than a rejection of family life, and while it undeniably strains demographic sustainability, it simultaneously nurtures new industries and forms of community connection that a purely economic account of the trend would overlook.

Why this answer earns band 8.5

The opening scenario, 'more likely to be asked about her dog's vaccination schedule than her fertility plans', replaces a generic claim like 'attitudes towards pets have changed' with a concrete image, which is what lifts Task Response above a formulaic introduction.
Rather than announcing the essay's structure mechanically, the introduction folds both halves of the question into a single sentence ('reshaping labour markets and social habits'), showing Coherence and Cohesion through implicit rather than signposted organisation.
The phrase 'crushing long-term commitment' would have been the flat 'big responsibility' in a weaker script; choosing an evaluative collocation instead strengthens Lexical Resource.
Giving the negative and positive effects one full paragraph each, rather than compressing the drawback into a single sentence, demonstrates Task Response by treating both halves of the two-part question with genuine equal weight.
The concessive structure in 'while it undeniably strains demographic sustainability, it simultaneously nurtures new industries' subordinates one clause to the other instead of simply listing two facts with 'and', which is what shows controlled Grammatical Range.

This answer includes invented specific detail written to show how detail is used, not to be quoted as fact: the figure of 200,000 dollars for raising a child in Singapore; and the claim that factories in Busan report difficulty filling apprenticeships. IELTS does not check facts, so this is about the texture, never the claim.
