The line graph illustrates data on the fast-food consumption of Australian youngsters, specifically focusing on the yearly intake of pizza, fish & chips, and hamburgers between the years 1975 and 2000.
Overall, it is apparent that the consumption of fish and chips experienced a marked decline over the years. In contrast, the consumption of pizza and hamburgers demonstrated a significant increase, with the latter maintaining its position as the most popular item during the latter half of the period.
Fish and chips were consumed a maximum of 100 times annually during the first 25 years. Despite experiencing a minor dip and rise in the following decade, it held the top spot until 1987. However, the demand for fish and chips continued to decrease thereafter, plummeting to approximately 40 times per year by the end of the period.
On the other hand, the yearly consumption of pizza and hamburgers was at its lowest in 1975, with only a slight increase of 5 and 10 times, respectively. In contrast to fish and chips, the intake of hamburgers rose the most, increasing by roughly 10 times by the end of the period. Pizza continued to rise until 1995, after which it plateaued and remained parallel to hamburgers for the remainder of the 25-year duration.
