How far back do background checks search?

Usually background checks cover all background history for all of the adult life of people you are searching. Public record databases online usually compile as much information as possible on any individual so it could be easily searched. However, sometimes in some states jurisidictions do not allow release of certain data. Or sometimes the data has not yet been computerized but in general most of the background reports contain all criminal offenses, civil judgments and other recorded criminal activity available as public record. Even bankruptcy records though they may not appear on your credit report after 10 years will still show up on a background check.
