The graph compares the proportion of household income spent on petrol in the United States and the United Kingdom.
Overall, the chart highlights two main trends: low-income households in both countries allocate a much larger share of their budget to petrol than wealthier groups, and American households consistently spend a higher percentage than those in the UK across all income levels.
In the lowest income bracket, American families spend just under 10% of their income on petrol, whereas the corresponding figure for the UK is slightly lower, at about 8%. As income rises, this proportion steadily declines. For middle-income groups, the percentage drops to roughly 5% in the United States and to about 4% in the United Kingdom.
The wealthiest households allocate the smallest proportion of their income to petrol. In both countries, the figure falls to below 3%, though the American figure remains marginally higher than that of the UK. This downward trend clearly shows that petrol constitutes a heavier financial burden for poorer households.
In summary, while petrol accounts for a declining share of expenditure as income increases in both nations, Americans tend to devote a consistently higher percentage of their household budgets to petrol than Britons, with the gap most noticeable among the poorest groups.
