Band 6+: The line graph highlights that the production of the world oil in four regions namely: middle east, africa, north america, asia, in four decades. Units measured in million barrels per day.

The line graph illustrates the amount of oil produced by 4 major areas of the world over a 40-year period, starting from 1960.

It is, overall, apparent that the amount of oil production rose significantly over the period in all these places studied. While Middle East extracted by far the highest amount of oil over most of the span, the smallest figures belonged to Asia.

Focusing on major oil manufacturers first, Middle East began the period with 20 million barrels per day, thereafter which raising its production to a peak of around 55 million barrels by 2000. Oil production in Africa, meanwhile, underwent a steep increase from approximately 16 million barrels in 1960 to 30m during the next decade, being the biggest producer of the time. However, its number fell to just over 20m before growing by about 20million barrels in the final year.

North America and Asia, however, produced relatively less oil. Although they both produced approximately 5m barrels in 1960, the count for the former grew markedly to well over 30m barrels, whereas the figure for the latter rose gradually and steadily amounting to only 20 million barrels/day.
