The line graph illustrates the key reasons why citizens choose to move to the countryside instead of staying in the capital city. In general, the majority of people leave because of the rising cost of living in big cities. Apart from this, there are increasingly population dissatisfied with the traffic conditions and lifestyle of the capital city.
The rising cost of living was always the fundamental problem. In 1990, about 65,000 people in this capital city moved away because of this issue. However, the figure rised into a peak for around 85,000 in 2000. When it came to 2010, the number of people departing the city due to this reason was then decreased slightly to 80,000.
Besides, traffic and lifestyle were another two reasons for citizens to leave their old homes. At first in 1990, the number of people leaving because of traffic was about the same as those who could not get used to the lifestyle, both around 20,000. Over the past decade, the numbers for both groups added steadily, while the figure for traffic reached a turning point in 2000. In 2010, the number of individuals leaving the capital city due to poor traffic conditions increased to 60,000, which was three times the original number. 40,000 people left because of lifestyle at the same year, which was twice the original number.
