Mercer County, Pennsylvania, has about 108,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Mercer County Sheriff's Office, 15 city agencies and eight campus, state or other agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Mercer County Court of Common Pleas. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Booking: Where People Arrested in Mercer County Are Held
A person kept in custody after an arrest in Mercer County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2023 the jail held about 230 people, down from about 290 in 2019. Its rated capacity in 2023 was 310 beds, and it ran at 75 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
