Funny you should say that. Marginal revolution cited a paper (http://muse.jhu.edu/journals/demography/summary/v047/47.3.patterson.html http://muse.jhu.edu/journals/demography/summary/v047/47.3.pa...) the other day, that supports your point, from the abstract: Using data from the U.S. Bureau of Justice Statistics and Census Bureau, I estimate death rates of working-age prisoners and nonprisoners by sex and race. Incarceration was more detrimental to females in comparison to their male counterparts in the period covered by this study. White male prisoners had higher death rates than white males who were not in prison. Black male prisoners, however, consistently exhibited lower death rates than black male nonprisoners did.
