The bar chart provides information about how many people in thousands were in prison in The UK, The USA, Australia, New Zealand, and Canada, over a fifty-year period between 1930 and 1980. In general, it is clear that the number of prisoners in four of the five countries fluctuated. In contrast, Great Britain was the only nation that witnessed an upward trend in the number of people imprisoned.
Starting at 120 thousand, the highest number of prisoners came from Canada in 1930 before it experienced a fluctuation in every decade. In 1970, even though the quantity of imprisoned people had a sharp fall to around 95 thousand, this figure increased a little compared to previous point at the end of the period. Similarly, the prisoner population in the United States saw the same trend, having a significant rise from 100 to about 130 over the decade, afterwards fluctuated in a thirty-year period. This trend is predicted to continue until the end of the period, reaching a peak of 135 thousand, placing it as the highest number of people in crime.
In addition, in the first ten years of the period, Australia and New Zealand had a sufficient quantity of prisoners which were about 70 thousand and 100 thousand respectively. Regardless of the data that both countries fluctuated rapidly for three decades, these trends remained stable in the same point of about 65 thousand in 1970, before Australia had a slight decrease of 50 thousand and New Zealand increased rapidly at approximately 85 thousand.
In spite of the fact that Great Britain had the lowest quantity of imprisoned people, which was about 25 thousand in 1930, this figure experienced a significant growth in every decade.
