California State Prison VS Contra Costa County Jail

Most people are familiar with the terms prison and jail, but they may not be aware of their differences. Contra Costa County jails hold people accused of a crime but have not yet been convicted, while California prisons house people who have already been convicted. Jails are generally smaller than prisons and have less stringent security measures. This is because people incarcerated in jails have not yet been found guilty of a crime, so they are assumed innocent until proven guilty.
By contrast, prisoners have already been convicted of a crime. They are looked at as guilty until they have served their sentence. As a result, prisons, in general, are larger than jails and have more security measures to prevent prisoners from escaping.
