The bar chart illustrates how the average GDP growth changed in developed countries, globaliser countries, and non-globaliser countries throughout four decades from the 1960s to the 1990s.
Overall, it is clearly seen that there was a constant upward trend in GDP growth for globaliser countries during the period, while the reverse was true for wealthy countries at the same period. The non-globaliser countries also experienced a downward trend but with fluctuations.
Regarding globaliser nations, the percentage of GDP growth stood at 1.5% in the 1960s, which was the the smallest growth rate among the three categories. This figure increased steadily to approximately 3% in the 1970s and 3.5% in the 1980s before reaching a peak at approximately 5% in the 1990s, taking the lead compared to the others.
Turning to non-globaliser countries, after rising slightly from around 2.5% in the 1960s to over 3.0% in the 1970s, the rate of GDP growth plummeted to just under 1% in the 1980s and then witnessed a slight increase in the 1990s, at 1.5%.
In terms of wealthy countries, the percentage of GDP growth was the highest in the 1960s, just under 5%. This figure saw a dramatic decline in the 1970s to under 3% before going down gradually to 2% in the 1990s.
