The table illustrates the average income and monthly petrol expenditure measured in dollars, along with the proportions of income spent in ten countries with the greatest cost of petrol.
Overall, Eritrea was the country with the highest petroleum-to-income ratio, followed by Turkey and Greece. Norway’s percentage was the smallest, accompanied by Britain and Belgium. Additionally, the inverse relationship between the average monthly disposable and the percentage spent on petroleum was exhibited, whereby a lower income typically resulted in a higher proportion, despite having the lower cost of petrol.
275 dollars of the 450.09 dollars of the average income in Eritrea was consumed by petrol costs, corresponding to 61.10% and resulting in Eritrea being the country with the highest percentage. On the other hand, similar oil prices only took up 7.70% of the wage in Sweden (275 dollars of 3548.81 dollars) and 8.70% of Belgium’s (273.05 dollars of 3125.88 dollars). In contrast, Norway had the lowest proportion at only 7.40% out of the 4329.07 regular salary.
Other countries followed similar trends: the higher the salary, the lower the percentage. Countries with superior earnings such as Holland (2880.98 dollars), Denmark (3430.34 dollars) and Britain (2681.57 dollars) all paid less than 15% of their revenue on oil, whilst the price in Italy (1832.15 dollars), Turkey (924.64 dollars) and Greece (1112.02 dollars) accounted for a much larger part of their received money.
