The bar chart shows the telephone call's time of the citizens in the UK between 1995 and 2002. From 1995 to 2002, the minutes of local calls are the longest, and the minutes of mobiles calls are the shortest.
The minutes of local calls in1995 and 2002 are pretty much the same. The minutes of the local calls from 1995 to 2002 have some fluctuates. At the start, in1995, there was around 70 billion minutes of local calls. Then it rose almost twenty billion minutes in the next four years. The minutes of local calls reached its peak in 1999. Then it begins to drop quickly. It dropped around twenty billion minutes between 1999 and 2002.
The time of national and international calls have a rise that is slow and smooth between 1995 and 1999. Then, it increased by about 10 billion minutes from 1999 to 2001. But it stopped to go up fast from 2001 to 2002.Infact, it only increased by a little bit.
The time of mobile calls jumped slowly and steadily from 1995 to1999 by approximately 8 billion minutes. Surprisingly, it began to rise like a monster between 1999 and 2002. It rose approximately 30 billion minutes at that period of time.
To put it into a nutshell, the minutes of mobile calls are rising faster than the other two calls. So I strongly believe that in the future the time of mobile calls in the United Kingdom will outrace the other two call's time.
