Band 9: graph below shows the average growth in domestic products in wealthy countries, countries that have adopted a global approach to business and countries that have not. Wite a report for a university lecturer describing the information below. Write at least 150 words.

The bar chart illustrates the average annual Gross Domestic Product (GDP) growth rates across three distinct categories: developed countries, developing countries, and the world average during the decades of the 1970s, 1980s, and 1990s.

Overall, it is evident that while the GDP growth in developing countries experienced a substantial upward trend, the growth in developed countries exhibited a consistent decline over the observed period.

In the 1970s, developed countries reported an average GDP growth of approximately 3.5%, a figure that diminished to around 3% in the 1980s and further decreased to nearly 2% by the 1990s. Conversely, developing countries experienced a notable increase in GDP growth, starting at about 5% in the 1970s, reaching approximately 3.5% in the 1980s, and escalating to nearly 6% by the 1990s. The world average GDP growth, while initially at 4% in the 1970s, observed a slight decline to just under 3% in the 1980s, and an increase to about 2.5% in the 1990s, reflecting trends that were less dramatic than those observed in either of the other categories.
