The graph shows the monthly expenditure on three types of restaurant food in Australia. The plot shows the annual number of restaurant visits for the same types of food between 1965 and 2015. Summarise the information in the charts and make comparisons where appropriate.

The bar graph shows the expenditure of different income groups in

Italian

,

Indian

and

Chinese

restaurants

in Australia,

while

the scatterplot shows the

number

of annual

visits

per

person

to the same type of

restaurants

between 1965 and 2015. The proportion of money spent on

Chinese

and

Italian

food

is similar for high ($42 and $20), medium ($35 and $14) and low ($13 and $8) income groups. As people’s income becomes higher, the proportion of money

that is

spent on

Indian

food

drops from being the most to least favoured style of

food

.

This

suggests that

Indian

food

is preferred because it is the least expensive option. In 1970 the total

number

of restaurant

visits

per

year

was approximately 5

visits

per

person

, which was made up of 3 and 2

visits

per

person

to

Chinese

and

Italian

restaurants

, respectively. The total remained low until 1985, but after that time increased steadily to around 50

visits

per

year

by 2015. After 1985, the

number

of

visits

to

Chinese

restaurants

increased in a continuous upward trend reaching 22

visits

per

person

per

year

by 2015,

while

visits

to

Italian

and

Indian

restaurants

initially

followed a similar trend but the

number

of

visits

began to level out after the

year

2000 reaching 15 and 12

visits

per

person

per

year

by 2015, respectively. People having higher disposable incomes and less free time are probably the causes of the dramatic change in eating habits.
