The line graphs delineate the population of imprisoned people categorized by their gender in a European country from 1911 to 2001.
Overall, the population of male and female prisoners experienced drastic changes through time. While the population of imprisoned women dramatically dropped, the male population increased. This suggests a difference between male and female mindsets and tendencies to commit illegal actions.
Looking at the first graph more closely, one can see that approximately 20,000 men were imprisoned initially. This population halved in 1931, then gradually increased back to its starting point over the following forty years. From 1981, the number suddenly rocketed to almost 40,000, then grew continuously to around 40,500 in 2001.
Considering the remaining gender, the number of incarcerated women experienced a steep drop from its peak of around 3,250 in 1911 to its trough at roughly 500 in 1941, reflecting a temporarily positive trajectory. However, the number then ascended slowly, reaching 1,250 within the next two decades and later 1,500 at the end of the time span. In comparison, the male prisoner population was four to twelve times more populous, likely due to the contrast in emotional and cognitive stability between the two genders.
