There is a lot of misinformation presented as fact when people talk about prison operations. As a scholar in the forensics field, I often heard from my professors that most inmates are in prison for narcotics-related crimes; I heard the war on drugs causes mass incarceration; and I heard mostly young black males are incarcerated. None of these things are true. This short post is to provide accurate numbers as to what type of offender is housed in California prisons. This data comes from the latest available numbers, June 2025.
