The average family size of jail inmates

I found more data (from the Survey of Inmates in Local Jails) on the question of whether criminals have fewer kids than non-criminals because of being locked up. I calculated the mean number of kids--biological, step, and adopted--of jail inmates ages 45-54 (sample size = 537). It's 3.04--not lower than the general population. Let's see if family size falls with a more serious criminal history:

Mean number of children

One lifetime arrest 3.00
Two 2.95
Five 2.86
Ten 3.38

More serious criminals have just as many kids as minor ones, and as many as non-criminals. The correlation between number of offspring and number of arrests is .04--basically non-existent.  Evidently, criminals are sufficiently alpha to have as many kids as anyone else, in spite of their low social status and time behind bars.

  1. is there any data on the length of their incarceration? you could be arrested 10 times for sentences of a few months, but it wouldn't compare to a single 25 year sentence.

    Which is why all criminals convicted of serious violence (murder, robbery, battery with GBI, etc) should receive bilateral orchiectomies along with imprisonment.

    "not lower than the general population"
    What is the general population?
    Also, I think there is a distinction between jail and prison. In my state, local jail is for 30 days or less. Prison is for incarceration for longer periods. If this is only for local jail visits, it would be for the more minor misdemeanor crimes.

  9. Ancient Rome had the same dynamic. There's nothing like the Dark Ages to help get rid of idiots on welfare. The people in the Dark Ages were ignorant, but they weren't dumb, the old Roman Mob starved itself out of existence.

    Mother Nature is very good at preventing idiocracies.
