The graph shows the number of telephones owned per thousand of the population in different countries over a five-year period. Overall, the number of phone owners per thousand of the population varied considerably. However, numbers tended to fall in countries with the highest level of phone ownership, whereas numbers generally rose in countries which had fewer phone owners in 2000.

By far the highest level of phone ownership was in Singapore, where just under 430 people per thousand were owners in 2004. This figure is slightly lower than the 2000 figure of around 460 per thousand. In Brunei Darussalam the second highest levels of phone ownership were recorded, and the numbers fluctuated around the 250 per thousand level across the five years. Countries like Cambodia and Vietnam had much lower levels of phone ownership and these increased up to 2004, rather than decreasing.

The bar chart shows the percentage of men in senior development position in three companies from 1980 to 2010.

While more men were in senior positions at Apple than other two companies in 1980 at 15%, the trend was fairly erratic with a 2% drop to 13% in 1985, followed by a rise of 1% five years later. In 1995, men held 7% more top development jobs than in 1990. After a slight drop back to 19% in 2000, by 2010 25% of top posts were filled by men.

By contrast, at IBM men fared much better. In 1980, 2% of senior posts were occupied by men with no change five years on. By 1990, the figure had increased to 13%, doubling to 26 per cent in 1995. Five years afterwards, there was a 6% increase in male senior development jobs with a near twofold jump in 2010 to stand at 63%, the highest for the three companies.

The situation was less remarkable at Microsoft than the other two firms except for the year 2010. In 1980, the percentage of senior posts held by men was 8% climbing at the rate of 2% in each subsequent period until 2000, after which it leapt to 45%. From the data, it is clear that men dominated senior posts at IBM by 2010.

Two graphs give different information related to eight professional groups. The bar chart indicates the number of weekly work hours done by the groups while the pie graph illustrates the percentages of people suffering from stress related illness in the different professions given.

In general, business men work the longest among the eight groups while the smallest amount of time is normally worked by lecturers. According to the pie chart, lecturers struggle the most with work-related stress. Although their average working hours is smaller than any other group in the chart, lecturers suffer from the highest level of stress caused by their job.

The bar graph shows that business men and movie producers work the most at about 70 hours and 62 hours per week respectively. At the opposite end of the scale, lecturers work only around 25 hours. Working hours of other professionals varied with doctors, writers, programmers, lawyers and chefs working approximately 52, 46, 35 and 32 hours per week in the name ordered.

The pie graph shows that the professional who has the highest incidence of stress related illnesses is lecturers at 25%. Movie producers and doctors also have high rates with 18% and 15% each. The figures for business men, lawyers, chefs and writers can be grouped into percentages between 11 and 8%. The lowest rate of stress illness is attributed to programmers at only 5%, which is only a fifth the figure for lecturers.

The bar chart shows the gender distribution of students doing computer scientific research across a range of disciplines at a US university in 2011.

In five of the six disciplines, males outnumbered females. Male students made up a particularly large proportion of the student group in subjects related to the study of programming objects: mathematics, programming, and engineering. The gender gap was particularly large in the field of mathematics, where there were five times as many male students as female students.

Men and women were more equally represented in subjects related to the study of computer science: natural sciences, psychology, and linguistics. In natural science, there were nearly as many women [approximately 200] as men [approximately 240]. This was also true of psychology. Linguistics was the only discipline in which women outnumbered men [roughly 110 women vs. 90 men].

Overall, the chart shows that at this university, computer science subjects continue to be male-dominated; however, women have a significant presence in fields related to psychology and the computer sciences.

The bar chart shows information about people’s drinking behavior by age group in the US. Several trends are evident.

The highest proportion of those who never drink (nearly two-thirds) was in the 16 to 24 years group. The proportion tended to decrease with age. Only 40 per cent of people aged 65 to 74 had never drink.

On the other hand, the percentage of those who had quit drinking tended to increase with age. Only 5 per cent of those in the youngest age group (16 to 24) were ex-drinkers, as opposed to roughly 40 per cent of those aged 65 to 75.

The percentage of those classed as heavy drinkers also showed a distinct pattern. People in middle age (35 to 54) tended to be the heaviest drinkers – approximately 13 per cent of the total. A relatively small proportion of those in the youngest age group, and an even smaller percentage of those in the oldest group (roughly 3 per cent) drink heavily.

Overall, age appears to be a significant factor in patterns of drinking behavior.

The bar chart depicts four types of waste disposal in four cities. Landfill was the most popular method of waste disposal in Toronto and Amman. Toronto used landfill for disposing of about three-quarters of its waste with the remaining quarter split between incineration, recycling and composting.

Amman used landfill for disposing of almost half of its waste with most of the rest being incinerated. Incineration was the most popular method of waste disposal in Madrid and Kuala Lumpur.

Kuala Lumpur disposed of more than half its waste by incineration with less than one quarter going for recycling and even less still going for landfill and composting. Recycling was the second least popular method of waste disposal.

No cities disposed of more than 25% of its waste by recycling and in the case of Toronto, it was less than 10%. Composting was the least common method of waste disposal. No cities disposed of more than 10% of its waste by compositing and Amman hardly did any composting.

The chart compares population shares in various regions of the world with the distribution of wealth in these same regions. It can be seen that population shares in almost all cases do not relate to the distribution of wealth.

Even though North America has only approximately 6% of the world’s population, it boasts nearly 34% of global wealth. A similar situation can be seen in Europe, which has 15% of the global population but 30% of global wealth, and the rich (high income) Asia-Pacific countries with 5% of the world’s population but 24% of its wealth.

On the other hand, the total wealth of people in China, India, Africa, Latin America and Caribbean, and the other poor (lower income) countries in Asia-Pacific is far less than their shares of the world population. This is most striking in India, where 16% of the world’s population own only 1% of the world’s wealth and in China, which has the highest percentage of global population (24%) but only 3% of the world’s wealth.

As we can see from the information, there was a general trend for the number of marriage to decrease over 13 years in most of the countries. In 1981, the USA had the most marriages (10.6 per thousand) but by 1994 this had fallen to 9.1 per thousands. The number of marriages also fell substantially in Finland and France. The only country where there was an increase in the number of marriage was Denmark.

By comparison the rate of divorce increased in most countries over the same period. The only exceptions to this trend were Germany, where there was no change, and the USA and Denmark, where the figure fell. The country with the fewest divorce in both 1981 and 1994 was Italy.
