The chart below shows the figures for imprisonment in five countries between 1930 and 1980. Write a report for a university, lecturer describing the information shown below.

The bar chart illustrates the

number

of prisoners in five

countries

in the period from 1930 to 1980.

Overall

, the highest level of imprisonment was in America and

Canada

,

while

the lowest was seen in New Zealand, Australia, and the UK.

It is clear that

the total

number

of people being imprisoned dropped slightly in the vast majority of these

countries

. Focusing first on the United States and

Canada

, in 1939, about 100 American citizens had been imprisoned,

whereas

for

Canada

, the corresponding figure was 120. By 1940, their

number

rose significantly to nearly 130 in America.

However

, in

Canada

, the level of imprisoned criminals dropped to slightly higher than 100, with its following decrease throughout the next years, with about 80 people in 1980. As for the United States, after a significant fall by nearly 40 units, by 1970, the

number

of prisoners increased sharply by the end of the period to almost 140. As for the remaining

countries

, about 30 British people were in prisons,

while

for Australia and New Zealand, the corresponding figures were considerably higher, with nearly 70 and 100 criminals. By 1970, the proportion of prisoners in these three

countries

was slightly lower than 70, with its increase to approximately 80 by 1980.

In contrast

, only less than 50 Australians were in prison

this

year.
