The bar chart below compares the number of prisoners (in thousand )caught in five different countries
(Great Britan, Australia, New Zealand, United States, Canada) over the years 1930 to 1980.
It is clear that the numbers of imprisonment in the USA and Canada are slightly higher over the years compared to the rest of the countries. On the other hand, the figures for Great Britain have been considerably low. At the same time, it is moderate in Australia and New Zealand.
In the year between 1930 and 1950, the countries experiencing a significant amount of imprisonments were America and Canada, which was around 100 -150 thousand. In 1930 New Zealand imprisonment activity was 100 thousand, which was the same as in America; after that, it saw a downfall by almost half in the next two decades. Great Britain, on the contrary, figures of Britain were between 20-40 thousand and were subsequently low than other five countries.
After the mid-1900s, the prisoners' rates rose in America and Great Britain, where Canada saw a fall by 20-40 thousand. Although the figures kept slightly fluctuating between 50 -60 thousand for Australia, they were relatively stable for New Zealand.
