The line graphs illustrate the proportion of expenditure on fuel, expressed as percentages of income, in the United States and the United Kingdom. Overall, it is evident from the graphs that the changing patterns for expenditure on both countries were steadily downward.
In detail, the proportion of expenditure on fuel by the poorest group in the United States was higher than the United Kingdom, at almost 4% of income, accounting for a peak of over 5% of income. As the graph progressed toward the middle-income, the expenditure on fuel declined steadily, maintaining betwen 4% and 5% of income. The least amount of income spent on fuel in the United States was represented by the richest group, at around 2.5% of income.
In contrast, the poorest group in the United Kingdom spent approximately 0.5% and 2.5% of income on fuel. As the graph addressed the middle-income group in the United Kingdom, the figures for fuel expenditure stood in the range of 2.5% and 3.5% of income. However, the pattern for fuel expenditure by the richest group in the United Kingdom was similar to that of the United States, constituting a decline to around 3% of income.
It can be understood that the poorest group in the United States allocated more income to spending on fuel compared to the poorest group in the United Kingdom. The spending patterns in both countries by the middle-income group was contrasting, with the United States going down, and the United Kingdom going up. Interestingly, the richest group expenditure on fuel in both countries was likewise, accounting for similar decreases.
