The CDCR Annual Report, which we began discussing here, provides some important information on the composition of the CA prison population, which might help decipher some of the mystery behind overcrowding.
In an interesting piece published last year, John Pfaff argues that prison population growth is not so much a factor of lengthy sentences (through such legislation as Three Strikes) but more of an increase of inmates serving short sentences. He also cautions against assuming that most of the population increase is a product of parole violations. His study, however, did not include California. The numbers provided by CDCR do not provide a conclusive explanation of what is going on, but they do allow some thought about the source of overcrowding.
Here, for example, is a snapshot of the breakdown of new admissions to CA prisons.
As we can see, a large percentage of new admissions, albeit not the majority of them, is due to parole violations. When focusing only on people admitted to prison for new offenses, the following picture emerges:
Serious, violent offenses, constitute a non-negligible, but by no means dominant, percentage of all admissions. When considering admissions for new offenses, violent offenders are about 33% of all incarcerations. However, when considering that new offenses provide only 25% of all inmates, it would appear that offenders incarcerated for violent offenses are only about 8% of all inmates.
What about the Three Strikes Law? The numbers of second- and third-strikers seem to be rather low.
Note that, while these lengthier incarcerations account for only a very small percentage of all inmates, their advanced age and medical expenses might account for a large part of the CDCR budget.
Stay tuned for an analysis of the parole data.
