The data represented in the pie chart and the accompanying percentages reveal some interesting trends.
Firstly, people are spending significantly more on cars and restaurants, nearly double the amount compared to previous years. In contrast, their spending on food has drastically decreased, dropping to about one-third of what it was in the 1970s.
Secondly, expenditures on furniture and petrol are relatively similar.
Thirdly, spending on computers has increased dramatically, reaching six times more than what was spent in the 1970s.
Finally, spending on books has seen a significant decline, now accounting for only about one-sixth of the spending observed in the 1970s.
