About the author
Thomas P. Bonczar is a justice statistics writer and analyst associated with the U.S. Bureau of Justice Statistics. In BJS publications, he is identified as a statistician, and his work centers on measuring imprisonment, parole, probation, and related correctional trends in the United States.
He is best known for reports including Lifetime Likelihood of Going to State or Federal Prison (with Allen J. Beck) and Prevalence of Imprisonment in the U.S. Population, 1974–2001. He also contributed to BJS publications on capital punishment, parole agencies, and national probation and parole populations, helping document how correctional systems changed over time.
Because the publicly available sources found here focus mainly on his government publications rather than his personal life, biographical details beyond his professional role are limited. What stands out most is the consistency of his work: careful, data-driven reporting that helped shape public understanding of incarceration in America.
