The bar chart provides a breakdown of the total number of minutes using for telephone calls in the UK by three categories: local, national and international, and mobiles over the period from 1995 to 2002.
One of the most outstanding features of this chart is that while the number of domestic calls made up an overwhelming majority, mobile calls experienced a gradual upward trend in this period.
As can be seen from the chart, starting at 70 billion calls, the proportion of local calls soared to reach the highest point of 90 billion calls in the first four years before plummeting by 20 billion in the last three years of the period. Conversely, there were considerable jumps in the total number of calls in both other types of calls. National and international calls slightly edged down throughout the 7-year- period; whereas having risen by a mere 2 billion calls, this figure for mobiles calls quadrupled to peak at just over 40 billion.
