The line graph displays the consumption rate of pizza, hamburgers, fish and chips by Australian teens between 1975 and 2000.
Overall, it is cleat that the value of pizza and hamburgers increased dramatically, while that of fish and chips fell significantly over the period. Another intersting point is that both hamburgers and pizza overtook the consumption level of fish and chips in late 1980s and mid 1990s, respectively.
Fish and chips were the most popular products among youngsters back in 1975 being eaten 100 times per year, before the figure fluctuated roughly about 85 and 95 times next ten years. The consumption value then continued to drop steadily year on year to just under 40 times by 2000, which made it the least preferable fast-food.
On the other hand, consumption of hamburgers rose sharply from approximately 10 to just over 80 in two decades, thereby overtaking that of fish and chips in mid 1980s. The figure then rose steadily to its highest value – over 100- by the end of the period. Pizza’s consumption showed similar trend by increasing steadily but significantly from about 5 to just above 85 by 1995. The figure finally stabilized around that level over the next five years.
