Đáp án

The bar chart illustrates the population changes in three cities—Smitten, Duffet, and Walebridge—between 1990, 2000, and 2010.

Smitten experienced a steady decline in population over the 20-year period. In 1990, the population was just over 3 million. It dropped to approximately 2.6 million in 2000, and further to 2.5 million by 2010. The total decrease of around 500,000 people suggests long-term outmigration or reduced birth rates.

In contrast, Duffet showed a strong upward trend. The population increased from around 2.5 million in 1990 to 3.5 million in 2000, and then reached approximately 4.6 million by 2010. This significant growth indicates rapid urban development and possibly higher employment opportunities.

Walebridge saw a gradual increase in population. Starting at about 1.8 million in 1990, the population rose slightly to 2 million in 2000 and then to 2.2 million in 2010. Although not as dramatic as Duffet, the upward trend shows steady urbanization.

In summary, while Smitten’s population declined over time, both Duffet and Walebridge experienced growth. Duffet had the most dramatic increase, whereas Walebridge’s growth was modest but consistent.
