The given table presents data concerning incarceration levels in five major nations around the world over a 50-year period.
Overall, imprisonment numbers varied considerably from one country to another. Likewise, the USA outperformed the figures for the remaining four countries.
In 1930, 100 thousand American citizens were sentenced to prison and subsequently rose by 30% the following ten years. Afterwards, statistics for the USA saw a steady decline prior to reaching a peak of 140 thousand in 1980. Australia and New Zealand also underwent a period of fluctuations with a gradual drop in the first half whereas there was an obviously upward trend in the second half.
Simultaneously, Great Britain had the lowest figure for confined people, occupying merely 20 thousand at the beginning of the period. Nonetheless, it had increased substantially by the end of the course, nearly tripling the 1930 mark. On the contrary, Canada experienced the most positive pattern with data falling by 20% from 1930 to 1980.
