The given bar chart illustrates how the number of landline telephones used by 1000 individuals changed across nine countries.
Overall, while the number of landline telephones in Vietnam and Cambodia increased, Myanmar remained unchanged, and the remaining countries decreased.
Focusing on the countries with the highest contribution rate, like Singapore, Brunei Darussalam, and Philippines, it can be seen that they experienced a downward trend throughout the period. For instance, people owned more than 450 landline telephones in Singapore; this figure fell to around 350. Likewise, Brunei Darussalam, whose ownership rate accounted for 250 at first, declined slightly to 225 in 2004.
Conversely, looking at the other two countries, namely Vietnam and Cambodia, it can be inferred that there was the same pattern within changes. Although their contribution rate was not as extreme as the previous countries, they were the only countries experiencing a gradual increase during this period, starting from approximately 25 in 2000, and reaching around 50 in the next four years. Moreover, the share for the remaining countries underwent various changes from decrease to increase, but they eventually hit the zero point.
