The graph shows the number of minutes of three types of phone calls in Australia between 1992-2000.
Summarise the information in the charts and make comparisons where appropriate.
Answer
The line graph shows the total daily call times for local, long distance and mobile calls in Australia from 1992 to 2000.
In 1992 the total time for local calls in Australia was approximately 72 million minutes per day and this increased by progressively smaller amounts and reached a maximum of 84 million minutes per day in 1996 before falling steadily to about 71 million minutes of calls per day in 2000.
In contrast, long distance and mobile call times increased throughout the period from 1992 to 2000. Long distance call times were around 32 million minutes per day in 1992 and increased steadily, reaching almost 49 million minutes of calls per day by 2000. In 1992 mobile call times were at only about 3 million minutes per day but this figure increased at an increasingly rapid rate reaching 10 million minutes per day by 1996 and 40 million minutes per day in 2000.
Overall, the number of calls increased with mobile calls appearing to replace local calls. In addition, increasing globalisation has probably led to a steady increase in the number of long distance calls.
