IELTS Essay on an Ageing Population: Both Sides and a Full Sample Answer

The ageing population question is one of the recurring IELTS Writing Task 2 themes, and it is one of the hardest to write well. The topic is not controversial, so candidates have no strong opinion to draw on, and the arguments sit in areas most people never discuss in English: pensions, healthcare funding, the retirement age, the size of the workforce.

The result is a predictable essay. Old people are a burden, the government should build more hospitals, in conclusion the government should take action. That is a band 6 answer written in correct English.

This post gives you the arguments on both sides in plain language, the vocabulary to carry them, and one complete essay with the reason behind every paragraph decision.

What the term means, and the question shapes it arrives in

An ageing population means the average age of a country's people is rising, because people live longer and fewer children are born. The share of people over 65 grows and the share of working age people shrinks.

The same subject reaches you in at least four shapes, and each one needs a different plan.

Read the final line of the prompt before you plan anything. Answering the wrong shape limits Task Response, the first of the four public band descriptors, however accurate the English is.

Argument bank: the problems

Each of these is a cause with a consequence attached. A cause alone is a list item; a cause with a consequence is development.

• A smaller workforce. Fewer working age adults pay tax, so the money available for public services falls at the same time as demand for them rises.
• Pension cost. Pensions are often paid from the taxes of people working now, so a longer retirement for more people has to be funded by fewer contributors.
• Healthcare demand. Older patients need more frequent and longer treatment, which means more staff and beds rather than simply more money.
• Care falls on families. Where state care is limited, adult children, most often daughters, reduce their paid work to provide it, which lowers household income and tax revenue again.
• Regional decline. Young people move to cities, so rural areas age fastest and lose the schools, shops and transport that would attract families back.

Argument bank: the other side

Most candidates cannot find anything to say here, which is why an essay that does say something stands out.

• Experience stays in the workforce. Workers in their sixties hold knowledge and judgement that takes decades to build, and many jobs now depend more on that than on physical strength.
• Longer life is a public health achievement. A rising average age is the result of clean water, vaccination and better medicine. It is a measure of success, not of failure.
• Older people do unpaid work. Grandparents providing childcare allow parents to work, and much volunteering in community organisations is done by retired people.
• A large older group spends money. Retired people with pensions and savings create demand for housing, travel, healthcare and services, and the jobs that supply them.
• Policy can change the arithmetic. Later retirement, higher participation by women in the workforce, automation and managed immigration all change the ratio of workers to retired people. The problem is a policy problem, not a law of nature.

Vocabulary that carries these ideas

You do not need technical terms. You need five or six precise ones used correctly, which is what Lexical Resource rewards.

Avoid burden as your main noun. It appears in almost every essay on this topic and it commits you to one side before you have argued for it.

Full sample answer

In many countries the proportion of people aged over 65 is increasing. Do the advantages of this development outweigh the disadvantages?

Populations in most developed countries are growing older, as life expectancy rises and birth rates fall. While a larger retired population does place real pressure on public funding, I believe the disadvantages outweigh the advantages at present, because the costs arrive faster than societies adjust to them. The clearest benefit is the experience that remains available to society. Workers in their sixties carry judgement built over decades, and in professions such as teaching, medicine and law that knowledge is difficult to replace quickly. Older people also perform a large amount of unpaid work. Grandparents who provide regular childcare, for example, allow both parents to stay in employment, which supports household income and tax revenue in a way that rarely appears in discussions of cost. The difficulty is that the financial pressure is immediate and the adjustment is slow. In countries where pensions are funded from the taxes of people currently working, a falling number of contributors must support a growing number of retirees, and healthcare demand rises at the same time. Treating an older patient typically requires more staff and longer care rather than simply more funding, so the shortage appears as waiting times rather than as a line in a budget. Raising the retirement age or increasing immigration can change this arithmetic, but both are politically difficult and take years to have an effect. In my view, therefore, the advantages are real but limited in scale, while the disadvantages affect the services that whole populations depend on. The balance would shift if governments acted earlier, and the fact that they generally do not is why I consider the disadvantages greater today.

That answer is 288 words.

What each paragraph was doing

• Introduction. Two sentences. The first explains the trend in one line without copying the prompt. The second gives a clear position, the disadvantages outweigh the advantages, with a reason attached, the costs arrive faster than societies adjust. The reason is what makes it a position rather than a label.
• Body 1. The weaker side, placed first deliberately. Two advantages, each developed: experience with examples of where it matters, and unpaid work with a specific case and its financial consequence.
• Body 2. The side the position supports. The pension mechanism is explained rather than asserted, and the healthcare sentence names the real symptom, waiting times. The final sentence concedes that policy can help, then says why that concession does not change the conclusion. Handling a counter argument inside the body is what separates development from assertion.
• Conclusion. No new argument. It restates the position in different words and names the condition under which it would change, which keeps the answer from reading as a template.

Three mistakes this topic invites

1. Writing about health instead of population. The question is about the proportion of older people, not about how to stay healthy in old age.
2. Inventing statistics. You do not need figures, and a false figure is a factual error. In many developed countries is safer and costs nothing.
3. One sided balance. A weighing question needs both sides present. Two sentences on the advantages and three paragraphs on the problems is not a balanced treatment, and Task Response notices.

What to do today

Take the four question shapes in the table above and write only the position sentence for each, one sentence per shape. Four sentences, ten minutes. The same argument bank serves all four, and the practice is in making the sentence fit the question rather than the topic.
