The chart represents the amount of gross domestic products from the 1960s to the 1990s, in terms of wealthy countries, globalizers and non- globalizers. In general, in a 4 decades period, globalizers saw a rapid increase while there was a decline in the proportion of GDP in wealthy and non- globalizers.
On the one hand, the percentage of domestic products in globalizers experienced a consistent growth in 40 years which was most considerable between the 1980s and the 1990s. In the last decade, they increased rapidly from 3.5% to nearly 5% and reached the highest peak over 40 years.
On the other hand, the proportion of prosperous and non globalizing countries saw differences. Initially the 1960s, the former peaked at around 4.5% which was the highest in this period. However, the next ten years experienced a significant drop to below 3% and until the 1990s, it decreased slightly and hit the bottom at 2%. Meanwhile, there was a dramatic fluctuation in the percentage of the latter. Non- globalizers grew by 1% in the 1970s but decreased sharply by above 2% between 1970s and 1980s and finally peaked at approximately 1,5% in the 1990s.
