In IELTS Writing Task 1, you will be asked to describe and explain a graph or table of data provided. There are 7 common types of questions in Task 1, including: Line Graph, Bar Chart, Pie Chart, Table, Mixed Charts, Process, Maps.
Below are some popular IELTS Writing sample essays:
Line Graph
Line Graph represents time factors. In this type of exercise, we often see changes and trends of one or more objects over a specific period of time. The vertical axis represents data and the horizontal axis represents time points.
Exam: The chart below shows the percentage of Australian people who were born in different places of the world. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

Sample IELTS Writing Task 1 for reference:
The line graph illustrates the proportion of Australians born overseas between 1976 and 2011.
Overall, it is apparent that the percentage of those born in the UK witnessed a downward trend while those from Asia and other places were on the rise. In addition, despite a moderate drop throughout most of the period, the total foreign-born population experienced a rising trend in the final decade.
The proportion of British-born Australians started around 15%, which was followed by that of other places (about 11%) and Asia (approximately 3%). Over the following ten years, both the UK and other places saw a falling trend whereas the reverse was true for Australians of Asia descent. From 1986 to 2001, the figures for the UK and Asia continued their respective trends while the percentage of Aussies born in other locations bucked its trend and increased considerably to almost 15%. The first 25 years also recorded a drop from roughly 23% to slightly over 20% in the overseas-born population.
In the 2000s, the percentage of Australian residents born in the UK had a gradual decline before finishing at just below 5%. Meanwhile, the figures for Asia and other places enjoyed increases, going up to high points of about 15% and 13%, respectively. There was also a significant rise in the figure for the total population to a peak of 25% in 2011.

Exam: The bar chart below shows the number of visitors to four London museums. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Sample IELTS Writing Task 1 for reference:
The bar chart compares the number of visits to four museums in London in five different months, namely June, July, August, September, and December. It is clear that the British Museum almost always leads in popularity, whereas the National Museum was the least prevalent choice for visitors in these months. In addition, visitor numbers fluctuated over time, with August seeing the highest visitor volume in all these sites apart from the Science Museum.
In the first two months, there were hardly any changes in the popularity of the four places such as the History Museum, the British Museum and the Science Museum received about 400,000 visits each, while visitor numbers to the National Museum hovered around 200,000.
However, the remaining months witnessed more remarkable changes, with the figures for the History Museum, the British Museum, and the National Museum soaring in August to peak at 600,000 visits, roughly 710,000 visits and slightly above 300,000 visits, respectively, before dropping significantly in September and December. Meanwhile, there was no change in the number of visitors to the Science Museum in August, which was followed by a marked rise to a high of 500,000 in September and a noticeable fall to merely 300,000 in December. It is worth noting that visitor traffic to both the History Museum and the National Museum was also lowest in the last month, at only 200,000 visits, more or less.
Vocabulary:

Exam: The charts show the percentage of people working in different sectors in town A and B in two years, 1960 and 2010. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

Sample IELTS Writing Sample:
The pie charts provide information on the proportion of people with jobs in three sectors, namely manufacturing, sales, and services, in two towns in 1960 and 2010.
Overall, it is clear that the manufacturing sector witnessed a significant increase in both towns A and town B over the 50-year period. There was also a decline in the proportion of people working in sales in both towns.
In 1960, town A's workforce was more evenly distributed than town B's which was more concentrated in the sales sector. More specifically, while two-thirds of the workforce in town A work in either manufacturing or services, sales workers in town B accounted for a massive 72%. This figure was almost double the percentage of those with sales-related jobs in town A (41%).
By 2010, manufacturing had become the dominant sector in town A with a hefty 64% of workers and had tripled to nearly a quarter of the labor force in town B. In contrast, the figures for sales in town A and B dropped to 20% and 54%, respectively. In addition, while the percentage of town A's workers with service-related jobs halved to 16% in 2010, the figure for town B rose slightly from 20% to 22%.
Vocabulary:

Data tables can be transformed into a variety of different chart formats.
Exam: The table below shows daily oil production in 4 countries from 2000 to 2004.

Sample IELTS Writing Task 1 for reference:
The table compares the number of barrels of oil produced in a single day in four African countries, namely Nigeria, Chad, Congo, and Somalia between 2000 and 2004. As can be seen, all countries witnessed an upward trend in their daily oil output, except for Congo. Noticeably, despite seeing the most rapid growth rate over 5 years, Chad remains one of the two smallest producers.
To begin with, there was a switch in ranks between Nigeria and Congo whose daily oil volume far outnumbered the other countries'. In 2000, Congo led in production, at 275,000 barrels whereas Nigeria only produced 205,000 barrels per day. However, in 2004, Nigeria overtook Congo to rank first with 213,000 barrels being produced in a single day, 10,000 barrels more than the figure for Congo.
However, the daily oil production in the other two countries was insignificant. specifically, 5000 barrels was the figure for Somalia in 2000, which then saw a steady rise until 2004 when it grew more than two-fold to reach 50,000 barrels per day. As for Chad, not until 2003 did this country record its very first 8000 barrels of crude oil produced on a daily basis and this amount surged to finish at an equal level of production to Somalia's in the last year.
Vocabulary:
- oil output (noun): oil output
- a switch in ranks (noun): a change in rank
- oil volume (noun): oil production

Mixed Charts
Mixed Charts are made up of the above types of exercises. Common pairs are pie charts – data tables, pie charts – bar charts. The charts all have certain relationships, you need to recognize and present them in the introduction of the article.
Exam: The table and pie chart gives information about the population in Australia according to different nationalities and areas. Summarize the information by selecting and reporting the main features and make comparisons where relevant

Sample IELTS Writing Task 1 for reference:
The pie chart illustrates the proportion of people of different nationalities in Australia while the table shows their whereabouts.
Overall, the majority of the population has Australian nationality. It is also apparent that people mostly reside in urban areas.
According to the pie chart, a hefty 73% of people living in Australia are Australians. This is followed by the figure for those who hold other nationalities (14%), which is twice as much as that for people of British origin (7%). The remaining groups only account for a minority of the population, with New Zealanders including 3%, the Chinese occupying 2% and the Dutch making up 1%.
Regarding the table, it is evident that an overwhelming proportion of residents in Australia are city dwellers regardless of their nationality. Almost all Chinese people, New Zealanders and British people live in cities, at 99%, 90% and 89%, respectively. Likewise, the figures for people of Australian and Dutch descent also show a preference for urban areas, with a ratio of around 8 urbanites to 2 country dwellers.

Exam: The picture shows the process of making wool. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Sample IELTS Writing Task 1 for reference:
The diagram illustrates how wool is produced for both personal and industrial use. Generally, it is clear that there are various steps involved, beginning with the sheep being sheared and ending with the woolen yarns being knitted or woven into commercially made jackets and carpets.
The process begins when the sheep are sheared for their fleece. Once the collective amount of fleece is cleaned with water and chemicals to get rid of contaminants such as grease, twigs, dried sweat, and other debris, it is taken to a drying machine. Following this, the fleece is carded, which results in tufts of wool and pieces of string as byproducts, with the latter being reintroduced into the process to maximize productivity.
Then, woolen tufts are sent to a warehouse for storage before being spun into balls of yarn. In the last stage, these yarn balls are sold for either individual pastimes, like knitting, or the commercial purpose of making jackets or carpets.

- Shear (v): to cut sheep's wool

Sample IELTS Writing Task 1 for reference:
The maps reveal some changes taking place to the layout of an art gallery's ground floor between 2005 and the present day.
In general, while the eastern part of the gallery has remained more or less intact over time, the opposite side has transformed significant transformations, with the whole area becoming more accessible for the disabled.
Originally, the gallery was designed merely for its exhibition purpose and visitors could enter the hall through the entrance in the south of the building. Inside the hall, there was a reception desk to welcome visitors, which led to a staircase in the north end. The remaining part simply consists of functional areas with a set of 3 exhibition rooms on the eastern wing, one large exhibition space together with an office taking up the entire southwestern corner, and a cafe in the northwest.
At present, the location has become modernized and versatile, providing more facilities for visitors, especially with the addition of a wheelchair slope right outside the entrance to the west and a lift next to the stairs. To the west, exhibition room 4 was converted into a children's indoor playground and one smaller room for temporary display, while a gallery shop and a vending machine were opened in place of the original gallery office and the cafe.
