On June 30, 2000, 7,600 youth younger than 18 were held in adult jails nationwide

Youth younger than 18 were 1% of jail inmates

According to the Bureau of Justice Statistics’ Annual Survey of Jails, an estimated 7,600 youth younger than 18 were held in adult jails on June 30, 2000. These under-18 inmates accounted for 1.2% of the total jail population and have been less than 2% of the jail population since 1994.

Most jail inmates younger than 18 were convicted or awaiting trial as adult criminal offenders (80%). They were held as adults because they were transferred to criminal court or because they were in states where all 17-year-olds (or all 16- and 17-year-olds) are considered adults for purposes of criminal prosecution.

The number of youth younger than 18 in adult jails in 2000 was 19%
lower than in 1999, but 14% higher than in 1994

  • The number of jail inmates younger than 18 held as adults was 6,100 in 2000—down 29% from the peak of 9,500 in 1999, but up 20% from 1994.

  • The number of jail inmates younger than 18 held as juveniles rose 50% from 1994 to a peak of 2,400 in 1996, then dropped 38% between 1996 and 2000—a total decrease of 7% from 1994 to 2000. In comparison, the total jail inmate population (all ages) increased 28% between 1994 and 2000.

  • The vast majority of youth younger than 18 in adult jails in 2000 were convicted or awaiting trial as adult criminal offenders (80%). In 1999 the proportion reached 90%, but since 1994 it had not been below 70%.

The Juvenile Justice and Delinquency Prevention Act limits the placement of juveniles in adult facilities

The Act states that “… juveniles alleged to be or found to be delinquent,” as well as status offenders and nonoffenders “will not be detained or confined in any institution in which they have contact with adult inmates .…” This provision of the Act is commonly referred to as the “sight and sound separation requirement.” Subsequent regulations implementing the Act clarify this requirement and provide that brief and inadvertent contact in nonresidential areas is not a violation. The Act also states that “… no juvenile shall be detained or confined in any jail or lockup for adults .…” This provision is known as the jail and lockup removal requirement. Regulations exempt juveniles being tried as criminals for felonies or who have been convicted as criminal felons from the jail and lockup removal requirement. In institutions other than adult jails or lockups or in jails and lockups under temporary hold exceptions, confinement of juvenile offenders is permitted if juveniles and adult inmates cannot see each other and no conversation between them is possible. This reflects the sight and sound separation requirement.

Some temporary hold exceptions to jail and lockup removal exist: a 6-hour grace period that allows adult jails and lockups to hold alleged delinquents in secure custody until other arrangements can be made (including 6 hours before and after court appearances) and a 48-hour exception, exclusive of weekends and holidays, for rural facilities that meet statutory conditions.

Some jurisdictions have established juvenile detention centers that are collocated with adult jails or lockups. A collocated juvenile facility must meet specific criteria to establish that it is a separate and distinct facility. The regulations allow time-phased use of program areas in collocated facilities.
