The bar chart compares the proportion of total production, categorized into Asia, Europe and the rest of the world, from 1840 to 2000.
Overall, it can be seen that the productions of Europe and Asia recorded downward trends, while that of the rest of the world experienced the opposite trend. Additionally, the figure for Asia remained the highest percentage in the last and first year of the period, while the rest of the world increased from the lowest proportion to the highest second figure at the end.
Regarding the decreasing categories, Asia’s production allocated approximately 52%, making it the highest percentage compared to the remaining others in 1840. However, it decreased significantly and hit a bottom of over 20% by 1960 before recovering dramatically to around 39% in the last year. Additionally, the total production of Europe witnessed nearly 40% in 1840, after which it increased considerably and reached a peak of approximately 49% by 1880, overtaking the first position of Asia, but later fell relatively to around 26% which was the lowest level by 2000.
Concerning the remaining another, there was nearly 10% in the production of the rest of the world, which was 5 times lower than that of Asia in 1840. Subsequently, it experienced an exponential growth and reached first rank at 40% by 1960 before falling slightly to around 36% in the next 4 decades.
