The bar chart demonstrates the three categories of telephone calls and their total numbers of minutes(in billions) in the UK from 1995 to 2002. Overall, during this period, the most calls were observed in local calls and minimum calls were in mobiles.
In local calls, a little more than 70 billions minutes were used in 1995 and then the figure that expresses the local calls increased until 1999.(90 billions minutes). From then until 2002, it declined and in 2002, the numbers were the same as the members in 1995. In national and international calls, a slightly less than 40 billions minutes were used in 1995 and the stats rose to 2002. In 2002, the numbers show that around 62 billions minutes were used. Although in 1995, roughly 3 billions minutes were used by mobiles, by 2002, approximately 45 billions minutes were used. The figure continued to grow steadily until 2002.
