SUMMARIZING, THERE WAS A SIGNIFICANT RISE IN THE INTAKE OF FISH & CHIPS AS WELL AS HAMBURGERS. HOWEVER, FISH & CHIPS TAKES THE HIGHER SPOT. THERE WAS A SLIGHT DECREASE IN THE INTAKE OF PIZZA OVER THE YEARS.
ON THE ONE HAND, A VERY FEW PEOPLE AS LESS AS ABOUT 90 HAD CONSUMED FISH & CHIPS IN 1970. THIS NUMBER SAW A DRAMATIC SURGE OVER THE YEARS GOING FROM 100 IN 1975 TO ABOUT 300 IN THE 1985 WITH AN INCREASE OF ABOUT 100 CONSUMERS IN THE SPAN OF A DECADE. IT CONTINUED ITS GROWTH AND REACHED A PEAK OF 500 IN 1990. ADDITIONALLY, THE GRAPH OF HAMBURGERS ALSO HAS A SIMILAR CURVE. IT BEGAN WITH ABOUT 20 CUSTOMERS IN 1970 WITH A TREMENDOUS UPWARD GROWTH OVER THE YEARS, REACHING A LITTLE OVER 100 PEOPLE CONSUMING IT BY THE END OF 1985. HENCEFORTH THERE WAS A SHARP RISE WITH THE NUMBER OF CONSUMERS BEING ABOUT 300 IN THE YEAR 1990.
ON THE OTHER HAND, THE GRAPH OF PIZZA CONSUMERS SHOWS A NEGATIVE GROWTH. IT HAD ABOUT 300 CONSUMERS AT THE BEGINNING OF 1970 WITH A STEADY DECLINE OVER THE NEXT DECADE WITH ONLY 200 CUSTOMERS. THEREAFTER, THERE WAS A GRAPH REMAINED CONSTANT WITH ONLY A CONSUMPTION OF AROUND 201 BY THE END OF THE TIME PERIOD IN 1990.
