The chart below shows the number of minutes in billions of telephone calls in the UK divided into three categories from 1995 2002

The graph illustrates the time, in minutes, of local, national and international, and mobile phone calls in the United Kingdom from 1995 to 2002.
Both national and international, and mobile phone calls grew significantly during the time period, while local telephone calls saw a slight decrease. Despite the fall, calls made locally remained the ones during which people spent the most time.

During 1995 to 1999, the time people devoted to calling others who live nearby climbed by 20 billion minutes, then peaked at approximately 90 billion minutes. The figure for national and international phone calls also rocketed, reaching 40 billion minutes in 1999. Meanwhile, mobile phone calls reported slower growth during the given period with an increase of 5 billion minutes.

After 1999, local calls began to drop, while the two other categories continued to grow. Mobile phone calls rose dramatically and peaked at over 40 billion minutes in 2002, doubling its figure in 2000. On the other hand, the amount of time people used on national and international calls increased more steadily, reaching its highest value at 60 billion minutes in 2002.
