 One of the most common and prominently noted differences is the appearance in women's prisons of pseudo-families, which, while they have been discussed in sociological texts since the 1930s, have not been noted in men's prisons at any point.This difference is a manifestation of gendered social factors which influence male and female populations within prisons and within larger society.The populations and demographics of male and female inmate populations in the US are very different from one another.
