The chart below shows the total number of minutes (in billions) of telephone calls in the UK, divided into three categories, from 1995-2002.

Summarise the information by selecting a report of the main features, and make comparisons where relevant.

Overall, most people tend to make calls by local line throughout the period shown. Meanwhile, the lowest figures on the chart are for mobile calls, however, this category also witnessed the most dramatic increase over 7 years between 1995 and 2002.

In 1995, local calls with fixed lines were used for a total of over 70 billion minutes, and around half of that amount was for national and international calls. On the contrary, a minority of UK citizens spent time on mobile calls. All three types of phone calls experienced a gradual increase during the next 4 years. 

By 1999, the number of minutes spent on local calls using landlines reached its peak of 90,000. Subsequently, the figures for this type fell steadily, but the rise in the other two kinds of phone calls continued. In 2002, the number of minutes of national and international landline calls passed 60,000 billion, while mobile calls increased to around 45 billion minutes.
