The line graphs illustrate the changes in the numbers of male and female prisoners in a European country from 1911 to 2011.
Overall, the figures of the male prison population were almost 10 times bigger than those of the female prison population during the observation period. Both of them showed a decline at the beginning and an increase by the end of the timeline.
The numbers of prisoners of both categories reached their minimum in 1931 for men and in 1941 for women at around 10000 people and around 510 people correspondingly. There was a dramatic rise to follow in the next 20 years for each category of prisoners and those figures almost doubled in 1951 and 1961.
The number of men imprisoned levelled off during the next 20 years before soaring up to 40000 between 1971 and 1981, continuing to grow steadily afterwards.
In contrast, The number of female prisoners plummeted at around 950 people at 1971 and was showing a slight growth up to around 1550 preople by 2001
