County jails are local facilities that hold individuals who have been arrested and are awaiting trial or sentencing. They also house people serving short-term sentences, typically for minor offenses. These jails are managed by local law enforcement agencies and are designed to detain individuals for a limited time. In contrast to state or federal prisons, which accommodate long-term inmates, county jails focus on short-term confinement. They often provide basic services such as meals, medical care, and access to legal resources. The conditions and programs available can vary significantly from one county to another.
