The provided bar graphs illustrate global manufacturing output, measured in percentage, from Asia, Europe and the other parts of the world over the surveyed years, commencing from 1840, at intervals of 40 years until 2000.
Overall, nearly all categories witnessed upward trends until the middle of the period and decreased subsequently, with only exception of Europe, where the production levels followed a contrasting pattern. Additionally, the other continents dominated production at the beginning, while output was overtaken by Asia in 1920.
Focusing first on other parts of the world, a half of production around the world was imported from many unidentified continents. In 1880, this figure remained 30 and slightly higher than Europe, subsequently the remainder of the world produced a small amount of products at about 20 in the following two years. However, this data proved to be short-term since reaching roughly 45 in the last year.
Turning to Asia, starting with an amount of production output equal to four-fifths of the rest of the world. In terms of production level, Asia accounted for the majority in 1880 and 1920, respectively approximately 45 and 50. In 1960, this data dropped to the same level as Europe, and ended at around 30.
Lastly, the manufacturing level of Europe was minimal in the first year, then it exhibited a significant increase until 1960 at around 40. In 2000, the figure for Europe declined to the same percentage as 1920 at about 30.
