Line Graph: Population Growth 1950–2050 Report (Band 9)
Band-9 Task 1 report on a population-growth line graph, with overview-first structure, trend vocabulary, and data-selection technique.
The line graph shows projected population growth in three countries from 1950 to 2050. Summarize the information by selecting and reporting the main features.
Band-9 sample report
The graph compares population trajectories in India, China, and the United States across a century, revealing a dramatic changing of the guard at the top.
Overall, India climbs relentlessly from the lowest base to become by far the most populous, while China peaks mid-period before declining. The United States grows steadily throughout but remains distant third in scale.
In 1950, China led with roughly 550 million people against India's 350 million and America's 150 million. Both Asian giants grew sharply through the late twentieth century, with China crossing one billion around 1980 and India following two decades later. The lines converge near 2020 at approximately 1.4 billion each — the historic crossover after which India pulls decisively ahead, projected to approach 1.7 billion by 2050.
China, meanwhile, plateaus after 2020 and then falls to about 1.3 billion, the graph's only sustained decline. The United States traces a gentler, uninterrupted ascent from 150 to a projected 400 million, never challenging the Asian scale but never faltering either. By 2050, the ranking is unambiguous: India first, China second, America a distant third.

Why this scores Band 9
Task Achievement (9): Overview identifies the three defining patterns (India's rise, China's peak-and-fall, America's steady third) with no data clutter. Details select crossovers, peaks, and endpoints — exactly what the criterion demands.
Coherence & Cohesion (9): Chronological grouping (1950 baseline, convergence era, projection era) with natural sequencing. Referencing ("both Asian giants," "the historic crossover") avoids repetition.
Lexical Resource (9): Trend precision: "climbs relentlessly," "changing of the guard," "plateaus," "uninterrupted ascent," "distant third." Dynamic verbs throughout.
Grammatical Range & Accuracy (9): Past simple for history, present/future for projections, participial phrases for variety. Clean.
Vocabulary to steal
- trajectories — paths over time (precise noun)
- changing of the guard — leadership switch (idiomatic, apt)
- pulls decisively ahead — takes the lead clearly
- historic crossover — lines crossing significance
- uninterrupted ascent — steady climb
- unambiguous ranking — clear final order
FAQs
How do I select data in a busy line graph?
Report starting points, ending points, crossovers, and peaks. Four to six key figures per line is plenty; examiners reward selection, not transcription.
What tense for future projections?
Past simple for historical data, will and is projected to for forecasts. Mixing them correctly around the present year shows range.
Do I describe every year shown?
Never. Group into phases: steady growth, sharp rise, plateau. Trends in phases demonstrate overview thinking, which is half your Coherence score.
