The three pie charts below show the changes in annual spending by a particular UK school in 1981, 1991 and 2001.
7
The three pie charts compare the year of 1981, 1991 and 2001 with regard to the modification in yearly expenditure of a selected British school.
Overall, teachers’ salaries accounted for the largest proportion in the total spending in all three years. While the shares in yearly expenditure of teacher salaries, furniture and equipment, and insurance increased, those of other workers’ salaries and resources experienced a drop.
In 1981, the overwhelming spending of this school went in teachers’ salaries, with the rate being 40% and this proportion climbed to 50% 10 years later, whereas in 2001, it decreased by 5%. By comparison, the cost of insurance of this school in 1981 represented merely 2%, which grew to 8% in 2001.
This school spent 28% of the money on other workers’ salaries in 1981 and nevertheless, this figure continued falling to 22% in 1991 and only 15% in 2001. The rate of resources and furniture and equipment experienced fluctuation from 1981 to 2001, respectively from 15% to 9% and from 15% to 23%.

The charts below give information on the ages of the populations of Yemen and Italy in 2000 and projections for 2050.
6.5
The Charts provided depict the current age distribution of Yemen and Italy’s population at 2000, as well as projections for the same nations in 50 years.
Overall, Yemen’s population has a lower average age across both periods, while Italy’s elderly population, hence average age increased noticeably.
Yemen in the Year 2000 has quite a high ratio of Children, just more than half at 50.1% of all. It has almost no elderly population, only 3.6% of all and the rest are working adults. We see this trend of high youthful population carry through to 2050, with more than half, at 57.3% of all population being working adults, 37% being children and just 5.7% being the elderly.
The situation is completely different in Italy. In year 2000, although there is a high ration of working adults in Italy, at 61.6%, the proportion of the elderly population is also staggeringly high, at 24.1%, more than 7 times the proportion in Yemen. This trend of overwhelming elderly population in Italy carries over into 2050, where the percentage increased almost twice fold, to 42.3%. The proportion of working adults and children in the population has also both decreased, amount to only 46.2% and 11.5%, both much less than the proportions in Yemen, for children 3 times as much.
C10 Test1
The first chart below shows how energy is used in an average Australian household. The second chart shows the greenhouse gas emissions which result from this energy use.
6.5
The two pie charts separately shed light on the volume of energy use through different means in an average household in Australia and the amount of greenhouse gas emissions from the same sources.
Overall, it can be seen that heating consumes more energy than its counterparts. It is also noticeable that water heating not only uses large amount of energy but also gives out the most detrimental gas.
In terms of the first graph, 42% of the energy usage in an average Australian family goes in heating, followed by water heating and other appliances that occupy respectively 30% and 15%. Then the figures drop precipitously, with refrigeration, lighting and cooling consuming 7%, 4% and 2%.
With regard to the second pie chart, heating emits merely 15% of the greenhouse gas despite the fact that it uses the most energy. As the second biggest energy consumer, water heating releases the largest amount of hazardous gas (32%). After that, other appliances and refrigeration separately give out 28% and 14% of the greenhouse gas and by contrast, lighting and cooling totally emit 11% of the gas.
C11 Test1
The charts below show the percentage of water used for different purposes in six areas of the world.
7
The pie charts provided show the percentage of water allocated for industrial, agricultural and domestic use. Overall, the more developed region of the world, namely North America and Europe allocates much more water for industrial use. In less developed or developing regions, such as Asia, South America and Africa however, much more water is diverted to agricultural use.
In more developed regions of North America and Europe, we see a somewhat similar ration of water usage: Around 50% for industrial use. It is a completely different story for other regions of the world. Africa, central Asia and South East Asia use much less water for industrial purposes, with the most being 12% of all water consumed in South East Asia, and the least in Central Asia, at only 5% of all water consumed in the region.
In contrast, these less developed or developing regions use much more water for agricultural purposes. Percentage of agricultural water usage amounts to more than 75%, save for south America at 71%. In central Asia, this percentage is the highest, at 88% of all water used. In Europe and North America, the percentage is much lower, at only 32% and 39% respectively.
As for domestic water usage, developing regions’ use much less than developed regions. While 13% and 15% of North America and Europe’s water usage is domestic, in Africa and Asia the figure is much less, at only 9% and 7% respectively. A anomaly of the pattern is South America, since its domestic water usage amounts to 19% of all water consumed.
C11 Test2
The charts below show the proportions of British students at one university in England who were able to speak other languages in addition to English, in 2000 and 2010.
6.5
The pie charts compare 2000 and 2010 with regard to the rate of English students in a selected university who have a command of other languages apart from English.
Overall, it can be seen that compared with 2000, a larger number of students could speak foreign languages in 2010. It is also noticeable that Spanish was the most popular second language for the students in this university.
Most of the students in this selected university were able to speak merely one language in addition to English. In 2000, 30% of the students could only speak Spanish apart from English and this figure rose by 5% in the following 10 years. Further, respectively 15% and 10% of all the students in this university spoke French and German as their second languages in 2010. The proportion of German remained unchanged 10 years later, while the rate for French witnessed a reduction by 5%. Additionally, the figure for students mastering another language lied in 15% in 2000 and climbed to 20% in 2010.
Also, there were students who had a command of two other languages and no other language apart from English in this university. Such students represented separately 10% and 20% in 2000 and by contrast, after 10 years these figures changed to 15% and 10%.
C14 Test1
The charts below show the average percentages in typical meals of three types of nutrients, all of which may be unhealthy if eaten too much.
6.5
The pie charts compare three types of nutrients, namely sodium, saturated fat and added sugar with regard to their average proportion in Americans’ meals.
Overall, it can be seen that breakfast contains the lowest rate of all the three nutrients. It is also noticeable that dinner occupies the highest rate of both sodium and saturated fat, while snacks contain more added sugar than its counterparts.
In terms of sodium and saturated fat, dinner makes up the highest percentage (43% and 37% respectively) and by contrast, the figure for breakfast remains the lowest being 14% and 16% separately. Apart from that, snacks also contain the lowest proportion of sodium as breakfast both representing 14% but its percentage of saturated fat reaches 21%.
When it comes to added sugar, snacks make up the largest proportion of 42%, followed by dinner and lunch (23% and 19% for each). In breakfast, individuals in the USA take in the lowest amount of added sugar, accounting for only 16% among three meals and snacks.

The pie charts below show the online shopping sales for retail sectors in New Zealand in 2003 and 2013.
7
The two pie charts compare the percentages of online sales across different retail sectors in New Zealand in the years 2003 and 2013. For three of the sectors, it is evident that over this time frame there was significant change in their proportion of online transactions.
At 36% we can see that the travel sector accounted for the majority of online sales in 2003, but this percentage had dropped to 29% by 2013. Across the same ten-year period, as an increasing number of people chose to purchase films and music online, we can see that transactions went from just 21%to 33%, making it the retail sector with the highest over all share of the online market.
In 2003, the clothing industry boasted an impressive 24% of total online sales in New Zealand. However, by 2013, the figure had fallen considerably to 16%. Interestingly, online sales of books eventually overtook sales of clothes, although books still represented only 22% of the market.
