The given line chart illustrates the proportion of expenditures across different categories for high school students between 2000 and 2020.
Overall, the amount spent by high school students on transport and leisure has significantly increased, while the spending on food and clothing has rapidly decreased over the two decades.
In terms of food, students began with 35% of their budget allocated to this category in the initial period, which slightly declined over the next five years. Between 2005 and 2010, the percentage remained steady at 30% before dropping to approximately 20%. Meanwhile, the proportion of spending on clothing started at 20% in 2000, but experienced a continuous fall of 5%, reaching the lowest percentage on this chart.
Additionally, transport and leisure categories began at 15% and 30% in 2000 respectively, showing significant increases by the final period, reaching 42% for transport and 33% for leisure.
In summary, the various expenditure categories have shown both rises and falls throughout the period. Furthermore, it seems that students are increasingly spending on transport and have upward trends in clothing.
