The line chart illustrates the oil consumption of a country over 6 decades, starting from 1950. The table gives information about the percentage of people who worked in oil industry and the overall unemployment rate during the same period.
From an overall perspective, while oil consumption and the number of workers in this industry increased, the national unemployment rate decreased. Over the first three decades, oil usage and employment overally remained same, followed by a slight increase in the following years.
According to the line chart, it can be seen that annual consumption of oil was around 20 million barrels in 1950, followed by a minimal increase in 1960, then returning to same amount in 1970. From 1970 to 2010, the consumption of oil witnessed a moderate raise, where it reached a peak of approximately 50 million barrels per year at the end of the period.
In 1950 and 1970, 1000 people worked in this industry which was 200 less employees than the year 1960. In 1980, this number nearly doubled and undergone an increase till it reached a peak of 3100 employees in 2010. Conversely, the unemployment rate experienced a reverse trend. While the proportion of people who had no jobs increased one percent in the first decade, there was a gradual decrease in unemployment rate in the next years. Compared to 4.1% of unemployed people in 1960, only 1.6% of people were jobless at the end of the period.
