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

The bar graph shows the combined time spent in billions of minutes, on three different kinds of phone call in the United Kingdom, from 1995-2002.

Overall, local calls were the most popular over the whole period, with national and international calls and calls on mobiles second and third respectively. However, the number of minutes spent on international and national calls and mobiles both increased over the period; with mobile minutes increasing dramatically, thus narrowing the gap between the three categories by 2002.

minutes spent on local calls fluctuated over the time period, with just over 70 billion minutes in 1995, peaking at approximately 90 billion in 1999 and then steadily decreasing to just over 70 billion minutes in 2002.

national and international calls increased steadily year on year, from just under 40 billion minutes in 1995 to a peak of just over 60 billion in 2002. mobile minutes increased at a very rapid pace from approximately 3 billion in 1995 to around 45 billion in 2002. mobile phone usage nearly doubled from approximately 22 billion minutes in 2000 to 40 billion in 2001.
