The line graph compares the fast food consumption of teenagers in Australia from 1975 to 2000.
Overall, it is clear that the consumption of fish and chips witnessed a downward trend, while the opposite was true for pizza and hamburgers. Additionally, the most significant fluctuation can be recorded in the figure of fish and chips.
Fish and chips, initially the most popular choice, experienced a continuous downward trend. In 1975, teenagers consumed fish and chips around 100 times per year. This figure fluctuated slightly in the early 1980s before entering a sharp decline, falling to around 40 times by 2000. The consistent drop in popularity may indicate a shift in preferences toward other types of fast food.
In contrast, the consumption of pizza and hamburgers surged dramatically throughout the period. Starting at approximately 5 times per year in 1975, pizza consumption increased gradually and then leveled off at around 80 times by 2000. The consumption of hamburgers followed a similar upward trajectory but grew more sharply, rising from approximately 10 times in 1975 to a peak of 100 times by the mid-1990s, before stabilizing slightly below that figure by 2000. These trends suggest that hamburgers and pizza gained immense popularity and became the preferred choices for Australian teenagers.
