Keynote – Task 1 Quick Guide

Direct Answer: For this task, focus on describing the main changes and comparisons in New Zealand’s population by age group from 2011 to 2012—highlighting increases, decreases, and the most significant trends, not every number.

Key Points to Remember:

• Identify which groups increased, decreased, or remained stable

• Use a four-part structure: Introduction, Overview, Body 1, Body 2

• Group information by age/trend, not only in data order

• Emphasize the most significant change or standout group

• Keep your writing precise, formal, and focused on summary and comparison

I. What Is This IELTS Writing Task 1 Question Type?

The question “Population of New Zealand from 2011 to 2012” is a typical IELTS Writing Task 1 trend and comparison chart (often shown as a table or line graph). It gives population data for New Zealand over two consecutive years and may include breakdowns by age group, gender, or region.

In this task, you are required to:

• Summarize and compare the population numbers/trends across different groups or years. This is similar to how you analyze data in IELTS writing task 1 comparative graphs.

• Highlight increases, decreases, and stability in total population or in specific groups (e.g., “population rose overall, but declined for the youngest age group”)

• Identify and report major contrasts, exceptions, or patterns within the data, such as growth in older groups or decline in others

You can review IELTS writing task 1 line graph graph with a trend to better understand this format.

Key elements to identify before writing:

• Years, categories, or breakdowns: Are you reporting by age, gender, region, or only totals?

• Direction and magnitude of change: Which groups increased or decreased? By how much?

• Important contrasts/patterns: Is overall growth small or large? Any age group or category stand out?

• Any stability: Did some groups remain nearly the same, while others changed dramatically?

II. Recommended Structure for Task 1

For a question like “Population of New Zealand from 2011 to 2012,” a high-scoring answer should follow a clear four-part organization.

• Introduction: Paraphrase the question and introduce the chart, table, or graph (mentioning years, location, and breakdowns if any). You can improve this skill by practicing paraphrasing in writing IELTS.

• Overview: Summarize the key trends and major changes or patterns (overall growth/decline, standout increases or decreases, main stability). You can improve this section by learning IELTS writing task 1 overview.

• Body Paragraph 1: Highlight the most significant or dramatic changes (e.g., largest increases/decreases, groups with clear trends). To structure your ideas better, refer to IELTS writing task 1 body paragraph.

• Body Paragraph 2: Present additional comparisons, secondary patterns, exceptions, or less extreme changes

1. Sample Essay on IELTS Writing Task 1 – Population of New Zealand from 2011 to 2012

Question:

The table below shows New Zealand’s population by age group in 2011 and 2012.

Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Sample Answer:

The table provides data on the population of New Zealand by age group in 2011 and 2012.

Overall, the country experienced a slight overall growth in total population, with the most significant increase seen in the oldest age group (65+), while the number of children under 15 declined.

The total population rose from 4.381 million in 2011 to 4.410 million in 2012. Most notably, the 65+ age group increased from 573,000 to 601,000 (a rise of nearly 5%), marking the largest proportional growth. The 40–64 age group also saw a small increase. By contrast, the population of those under 15 years fell from 898,000 to 896,000, and the 15–39 age group decreased from 1.658 million to 1.647 million.

In summary, New Zealand’s slight population growth from 2011 to 2012 was mainly due to an increasing number of elderly residents, while the population of younger people declined.

Why this essay works well:

• Introduction paraphrases the prompt concisely and completely

• Overview summarizes the main trend (growth, demographic shift toward older population)

• Body paragraphs are logically grouped: (largest change, minor/negative trends)

• Key data chosen strategically—focus on percent, relative size, and pattern

• Academic tone and clear language

2. Useful Language for This Task Type

When describing population trends in New Zealand from 2011 to 2012, it’s important to use clear vocabulary for comparison, growth or decline, and proportions. Here are useful phrases to strengthen your response:

Task Achievement

  • Clearly highlight increases, decreases, stability, or major shifts.

  • Provide a clear overview (e.g., “population grew slightly, mainly due to an increase in the oldest group”).

• Do not list all numbers—focus on the main contrasts and overall patterns.

Coherence and Cohesion

• Organize your answer in four paragraphs (Introduction, Overview, Body 1, Body 2).

• Group details logically (by age group, direction of change, or trend).

• Use logical linking and comparison language: “by contrast,” “while,” “however,” “meanwhile,” “whereas.”

• Avoid jumping back and forth between years or age groups without a logical sequence.

Lexical Resource

• Use a range of vocabulary for describing population changes: “increase,” “decline,” “remain steady,” “account for,” “category.”

• Use comparison and quantifying language: “the largest increase,” “a marginal drop,” “fell slightly,” “rose by nearly five percent.”

• Avoid repetitive or vague words; maintain an academic and objective tone.

Grammatical Range and Accuracy

• Use both simple and complex sentence structures; compare groups using accurate grammar.

• Use the past simple for completed years (“rose,” “decreased”).

• Employ comparatives, superlatives, and range expressions: “the biggest change,” “the only group to increase,” “the sharpest decline.”

• Maintain accuracy in verb forms, articles, and agreement.

A high-scoring answer groups similar trends, focuses on the main changes, uses precise vocabulary, and organizes points logically with clear language throughout.
