Model answer

Band 8 sample answer

Band 8180 words. Every figure in the answer comes from the chart above.

The line graph illustrates the historical and projected population figures for India and China between 2000 and 2050. Overall, it is clear that India is set to undergo a steady upward trend, whereas China’s population trajectory is expected to follow a bell-shaped curve.

In 2000, India had a population of 1.0 billion, significantly lower than China’s 1.26 billion. Over the following three decades, India’s population grew consistently, reaching 1.45 billion by 2030. During this same timeframe, China’s population also increased, albeit at a slower rate, rising from 1.26 billion to a peak of 1.45 billion in 2030, at which point the two nations’ population figures intersected.

From 2030 onwards, the trends diverge sharply. India’s population is forecast to continue rising, albeit at a slightly moderated pace, reaching 1.59 billion by 2050. Conversely, China is projected to experience a gradual decline after 2030, with its population falling to 1.39 billion by 2050. Consequently, by the end of the period, India is expected to have a substantially larger population than China, reversing the demographic situation observed at the start of the millennium.

Frequently asked questions

What should the overview say?+

While India's population is projected to experience continuous growth throughout the period, China's population is expected to peak around 2030 before beginning a gradual decline.

How many words and how long for IELTS Writing Task 1?+

At least 150 words; 170 to 200 is the safe range. Spend about 20 minutes on it and leave 40 for Task 2, which carries twice the marks.
