The Legal Drinking Age IELTS Essay: How to Use Country Comparisons as Evidence

Ask a candidate to support an argument about the legal drinking age and something predictable happens. A number appears. Studies show that 73% of road accidents involve drivers under 21. Nobody wrote that study. The candidate invented the figure in about four seconds because the essay felt like it needed one.

You do not need invented numbers, and they do not help your band. What helps is a comparison you actually know to be true. Countries set their drinking age differently, and that difference is free evidence you can use in any essay about law, age limits, or personal responsibility.

This post shows what counts as evidence in IELTS, how to use a country comparison properly, and what the same paragraph looks like before and after.

Examiners are not checking your facts

This is the part most candidates have never been told clearly. The four public band descriptors are Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. None of them asks whether your example is factually verified. There is no fact checking step and no citation requirement.

What Task Response does ask is whether your ideas are extended and supported. A supported idea is one where you explain how the example connects to your claim. An invented statistic skips that explanation entirely, which is why it does not earn the marks candidates hope it will.

So the question is not is this true enough to survive checking. The question is does this example do explanatory work. A precise fake number does none. A real comparison you can reason about does a lot.

Why country comparisons work so well

A country comparison gives you three things at once.

1. A contrast. Two systems that differ on exactly the variable you are discussing.
2. A reason to explain. Once you name the difference, the natural next sentence explains why it exists or what follows from it, and that sentence is the development the descriptors reward.
3. Safe precision. You are naming a law, not claiming a research finding. Laws are public and stable.

Here are widely known examples in this topic area. Use only what you are confident about, and keep the claim simple.

You do not need all six. Two contrasting cases are enough for one paragraph. Naming six turns your paragraph into a list, and lists do not develop.

Before and after

Here is the question:

Some people believe the legal drinking age should be raised to 21 in all countries. To what extent do you agree or disagree?

Before

I disagree with this idea. Research has proven that raising the drinking age does not work. According to statistics, about 65% of young people in countries with a high drinking age still drink illegally, and studies show that alcohol related deaths only fell by 12%. Therefore a high age limit is not effective and creates more problems for society.

Three invented figures in four sentences. Every one of them replaces an explanation. The paragraph tells us the writer's conclusion twice and never tells us why. Lexical Resource and grammar here are fine, but Task Response has nothing to reward, because no idea is extended.

After

I disagree, mainly because the age limit matters less than the culture around it. The United States sets one of the highest limits in the world at 21, while Germany allows beer and wine at 16. If a higher limit reliably produced more responsible drinking, we would expect the German outcome to be clearly worse, and it is not obviously so. The likely reason is that German teenagers usually encounter alcohol in small amounts at a family table, where an adult is present and the quantity is limited, whereas a 20 year old in a country with a limit of 21 encounters it in private, without supervision, and often in a hurry because the drinking itself is the offence. The limit changes where young people drink far more than whether they drink, and unsupervised drinking is the more dangerous of the two.

No numbers at all. The paragraph is stronger because the comparison forced an explanation: two named systems, a prediction, and a mechanism for why the prediction fails. That mechanism is the development.

Notice also the hedging. Not obviously so and likely reason are honest and cost nothing. Confident overstatement is not rewarded; careful qualification is normal academic language and often shows better control of the sentence.

How to build the comparison in your plan

Add one line to your usual four line plan.

1. Position.
2. Body one idea.
3. Comparison that tests the idea. Which two countries, and what differs.
4. Body two idea.
5. The limit of your position.

Line 3 takes about twenty seconds to fill in and changes the whole paragraph. Ask yourself: if my claim were true, what would we see in the country that does it differently? Then write the answer to that question.

Four rules for using real evidence

1. Name the system, not a number. Germany permits beer at 16 is safe. In Germany, 43% of 16 year olds drink weekly is invented unless you genuinely know it.
2. Never write the word statistics without one. If the sentence begins studies show, delete it and write the mechanism instead.
3. Two cases, not six. A comparison develops. A list does not.
4. Hedge when you are unsure. It appears that, one likely reason is, in many countries. These phrases are accurate and they are good academic English.

The same technique on other topics

Country comparisons work anywhere a policy differs across borders. Compulsory voting exists in Australia and does not in the United Kingdom. School starting age is four in England and seven in Finland. Military service is compulsory in South Korea and not in Japan. Each of those pairs gives you a ready made test for a claim about the policy, and none of them requires a number.

Try this today

Take one Task 2 question you have already answered and find its invented statistic. There will probably be one. Delete it, then replace it with a two country comparison and one sentence explaining what the difference implies. Compare the two versions and count how many sentences in each actually explain something.

When you write the new version, you can run it through Bandly to see estimated bands for each of the four criteria and where the reasoning still looks thin. The estimates come from a language model rather than a qualified examiner, so use them to check whether your support paragraphs are doing real work, not as a prediction of your test day score.
