IELTS Essay: Ageing Population (Band 9 vs 6.5)
In short
Below is a full Band 9 model answer to this IELTS Writing Task 2 question, the same question written at Band 6.5, and a criterion-by-criterion breakdown of exactly what separates them — so you can see what to change in your own writing. Then check your essay with the free tool.
The question
In many countries, people are living longer and the proportion of older citizens is steadily rising. Do the advantages of an ageing population outweigh the disadvantages?
How to approach a Advantages–Disadvantages question
For an advantages/disadvantages question, first check exactly what is asked: 'discuss the advantages and disadvantages' wants a balanced account, whereas 'do the advantages outweigh the disadvantages?' demands a clear verdict. If a verdict is required, state it in the introduction and return to it in the conclusion — listing pros and cons without deciding is a Task Response failure.
The plan
- 01Introduction: describe rising life expectancy and an ageing population, and state that the disadvantages outweigh the advantages.
- 02Body 1: advantages - older citizens' experience and free childcare from grandparents ease pressure on families and the labour market.
- 03Body 2: disadvantages (dominant) - a shrinking taxpayer base, soaring pension and healthcare costs, and staff shortages create lasting strain.
- 04Conclusion: restate the weighted judgement that the fiscal and workforce drawbacks are more significant.
Band 9 model answer
In numerous nations, rising life expectancy and falling birth rates are producing societies in which the elderly form an ever-larger share of the population. Although this trend brings certain benefits, I would argue that its drawbacks are, on balance, more significant.
There are undeniable advantages to a greying society. Older people constitute a vast reservoir of experience and skill, and many continue to contribute long after the conventional retirement age, whether by mentoring younger colleagues or founding businesses of their own. They also underpin family life on a practical level: grandparents who provide childcare free of charge enable both parents to remain in employment, easing pressure on household finances and on the wider labour market. In this sense, an ageing citizenry can be a quiet economic asset rather than a mere burden.
Nevertheless, the strains such a demographic shift imposes are, to my mind, weightier. As the ratio of retirees to workers climbs, a shrinking taxpayer base must shoulder soaring pension and healthcare costs, a burden that risks either crippling public finances or forcing painful cuts elsewhere. Chronic staff shortages in medicine and elderly care compound the problem, since there are simply too few younger workers to meet the escalating demand. These pressures are structural and long-lasting, and they are far harder to remedy than the benefits are to sustain.
In conclusion, while an ageing population offers valuable experience and much-needed family support, the fiscal and workforce challenges it creates are ultimately more profound and far more difficult to solve. On balance, therefore, the disadvantages of this demographic trend clearly outweigh its advantages.
The same question at Band 6.5
These days in a lot of countries people are living more longer than before and the number of old people is increasing every year. Some people think this is a good thing but other think it is bad. In my opinion, the disadvantages of this situation are more than the advantages.
On the positive side, there are some good points of having many old people. Old people have a lot of experience in the life and they can give good advice to the young generation. Also many grandparents help to take care of the children when the parents are working. This is very helpful for the family because they don't need to pay money for the babysitter. So old people can be useful for the society in some ways.
However, there are also many problems with the ageing population. The biggest problem is that the government have to spend a lot of money for the pension and the health care of old people. But there are less young people who are working and paying the tax, so this is very difficult. Another problem is that there is not enough workers in the hospitals to take care of so many old patients. This can make the situation more worse for everyone.
In conclusion, even though the old people can help the family and give experience, I think the problems like money and workers are much more serious in the long term. So in my opinion the disadvantages of the ageing population are more than the advantages.
What separates them, criterion by criterion
| Criterion | Band 9 | Band 6.5 |
|---|---|---|
| Task Response | Reaches a clear overall judgement ('the disadvantages... clearly outweigh its advantages') and weighs both sides with developed reasons. | Answers the outweigh question and lists points, but they stay general (e.g. old people 'can give good advice') and are not deeply explored. |
| Coherence & Cohesion | Moves between ideas smoothly ('Nevertheless, the strains such a demographic shift imposes are... weightier') and refers back cleanly. | Organises with basic markers ('On the positive side', 'However', 'Another problem is') and adds ideas in a list. |
| Lexical Resource | Uses precise collocation such as 'a shrinking taxpayer base', 'soaring pension and healthcare costs' and 'chronic staff shortages'. | Repeats plain vocabulary such as 'old people', 'problem' and 'money' throughout. |
| Grammatical Range & Accuracy | Manages varied complex sentences accurately, e.g. 'As the ratio of retirees to workers climbs, a shrinking taxpayer base must shoulder...'. | Uses simpler forms with errors such as 'living more longer', 'the government have' and 'less young people'. |
Examiner's note
The Band 9 answer delivers a clearly weighted judgement, develops both advantages and disadvantages with specific consequences, and uses accurate, sophisticated language. The Band 6.5 essay addresses the task and is organised logically, but its ideas remain general, its cohesion is mechanical, and comparative errors such as 'living more longer' and 'more worse' hold it back.
Vocabulary from the Band 9 answer
| Word / phrase | Meaning |
|---|---|
| rising life expectancy | the fact that people are living longer on average |

| the conventional retirement age | the usual age at which people stop working |
| a quiet economic asset | a valuable but often unnoticed contributor to the economy |
| a shrinking taxpayer base | a falling number of people who pay taxes |
| soaring pension and healthcare costs | rapidly rising costs of pensions and medical care |
| chronic staff shortages | a persistent, long-term lack of workers |
Frequently asked questions
Does 'do the advantages outweigh the disadvantages' require me to choose a side?
Yes. This wording asks for a clear judgement, so you must state whether the benefits or the drawbacks are greater and support that view consistently throughout.
Should I write about both advantages and disadvantages even if I favour one?
Yes. You need to cover both to answer fully, but you can give more weight and development to the side you believe is stronger, which signals your position.
Where should I state my position in this essay type?
State it in the introduction and restate it in the conclusion. Making your judgement explicit early helps the examiner follow your argument and improves your Task Response score.
