Detailed Process and Observations

Data Summary:

The line graph illustrates the total volume of telephone calls made by Danes in three categories—national landline, international landline, and mobile calls—over a 10-year period from 1995 to 2004.

1. National Landline Calls :

Starting with around 12 million minutes in 1995, national landline calls increased, peaking at 15 million minutes in 2001. However, there was a significant decline in usage after 2001, dropping to 8 million minutes by 2004.

2. International Landline Calls :

International landline calls started at 6 million minutes in 1995, gradually increasing over the period to reach just over 7 million minutes in 2004. This shows a steady but moderate growth compared to the other categories.

3. Mobile Calls :

Initially the least used, with less than 1 million minutes in 1995, mobile calls grew steadily until 2000, after which usage surged rapidly. By 2004, mobile call volume had reached 12 million minutes, reflecting a shift in preference toward mobile usage among Danes.

Sample Answer

The line graph illustrates trends in the total volume of telephone calls across three categories—national landline, international landline, and mobile calls—in Denmark from 1995 to 2004.

In 1995, national landline calls dominated, totalling approximately 12 million minutes, while international landline calls accounted for 6 million minutes, and mobile calls were below 1 million minutes. National landline call volume steadily increased, peaking at 15 million minutes in 2001 before declining sharply to 8 million minutes by 2004.

International landline calls saw a gradual rise, reaching slightly over 7 million minutes in 2004, showing a stable but modest increase over the years. In contrast, mobile call volume started low, but from 2000 onward, it grew significantly, reaching 12 million minutes by 2004, nearly matching the peak of national landline calls from previous years.

Overall, mobile calls gained remarkable popularity, especially after 2000, while national landline usage declined, indicating a shift in communication preferences in Denmark.
