Men are 93% of prisoners: https://www.prisonstudies.org/news/world-female-imprisonment-list-fourth-edition

Men were 97% of those executed globally in 2020: https://www.amnesty.org/en/latest/news/2021/04/death-penalty-in-2020-facts-and-figures/

I know what you're thinking: Well men commit more crimes so this is a non-issue! But its more complicated than that.

Unfortunately, men can face discrimination in the legal system. For example, in the USA justice system, Sonja Starr found that men were being disadvantaged: https://repository.law.umich.edu/law_econ_current/57/

"This paper assesses gender disparities in federal criminal cases. It finds large gender gaps favoring women throughout the sentence length distribution (averaging over 60%), conditional on arrest offense, criminal history, and other pre-charge observables. Female arrestees are also significantly likelier to avoid charges and convictions entirely, and twice as likely to avoid incarceration if convicted."

This is one of the reasons men are more likely to go to jail than women. Anothe reason is the Duluth model which says that if a man and woman are in a relationship and someone calls the police the man should be arrested. This makes it seem that men are more likely to be abusers than men.

Men are often subjected to rape, torture, and other unpleasant experiences in prison. Many commit suicide or self harm.

Should prison and the death penalty be seen as a man's issue?
