The provided charts illustrate the annual oil consumption, the number of people employed in the oil sector, and the national unemployment rate in a small country between 1950 and 2010.
Overall, oil consumption and industry employment grew significantly over the sixty-year period, whereas the national unemployment rate showed a steady decline. Notably, the growth in oil-related jobs appears to correlate with the broader reduction in national unemployment.
In 1950, oil consumption stood at 20 million barrels, rising slightly to 23 million by 1960 before dipping to 19 million in 1970. From 1970 onwards, consumption grew consistently, reaching 30 million in 1980 and climbing to 50 million by 2010. Similarly, employment in the oil industry began at 1,000 people in 1950, remained stable until 1970, and then increased steadily to reach 3,100 by 2010.
Conversely, the national unemployment rate started at 4% in 1950, peaking at 4.1% in 1960. From 1970, when unemployment was 3.9%, the rate fell consistently throughout the following decades. By 2010, the national unemployment rate had dropped to 1.6%, representing a significant improvement compared to the figures recorded at the start of the period.
