Writing task 1 – Bar chart
The chart below shows the total number of minutes (in billions) of telephone calls in the UK, divided into three categories, from 1995-2002.
The bar chart compares the data of the amount of user minutes for phone calls in terms of three different types between 1995 and 2002.
It is clearly that UK saw a general increase on national, international calls and mobile calls during the period shown. By contrast, local calls were varied more significantly than the others did.
By the year 1995, local calls were by far the most popular trend, at approximately 72 billion minutes, compared to national and international calls and mobile calls, at 37 billion minutes and just 4 billion minutes respectively. From 1996 to 1999, the time spent for all three kinds of telephone calls were gradually increased, especially the figure for local land lines reached its peak, to exactly 90 billion user minutes. Meanwhile, the rise in mobile calls in 1999 was over double the number of that in 1995, around 12 billion minutes.
Throughout the remainder period, Britain saw a dramatic increase in mobile calls, at its highest point of 45 billion minutes. Furthermore, the figure for national and international land lines was increased steadily to surpass 60 billion minutes in the period shown. On the other hand, the time spent on local calls went down to relatively the same amount of the year 1995, about 72 billion minutes.
