Sometimes young people break the law. 
Long ago, rules were very harsh. Children were treated like adults in court. This was often not fair.
Later, new courts were made for kids. These courts focus on helping people change. They do not just use punishment.
Many things can affect how kids act. Friends and family can have a big impact. Staying safe and following rules is important.

Sometimes young people break the law. We call this juvenile delinquency. These acts would be crimes if adults did them. 
Long ago, rules were very harsh. Before the 18th century, children were tried in adult courts. They could even face the death penalty. Later, Illinois made the first juvenile court. This court focused on helping kids instead of just punishment. It also kept records private.
Today, laws change by place. In the United States, most states say a juvenile is under 18. Some states, like New York, moved that age up. In Japan, the age was lowered to 18 in 2022.
Many things can affect how kids act. Family and friends play a big role. For example, how parents discipline a child matters. Some kids also join groups that lead to bad choices. Some experts say that more jails instead of more schools can also be a problem. Most young crime is not violent. We can help kids by using restorative justice. This means focusing on making things right.
Juvenile delinquency is a term used when young people break the law. These acts are things that would be crimes if an adult did them. Experts often group these actions into three different types. Some are called status offenses, which are only illegal because the person is a minor, like drinking alcohol. Other acts are regular crimes that are handled by the criminal justice system. There are also offenses that go through juvenile courts specifically. 
Rules for young people have changed a lot over time. Before the 18th century, children as young as seven faced adult courts. They could even face the death penalty for their actions. This changed when Illinois established the very first juvenile court. This new court focused on treatment instead of just punishment. It also kept the records of young people private. This was a big shift in how society helped young people.
Today, the age for being a juvenile varies by place. In the United States, most states say a juvenile is under 18. Some states like Michigan and New York raised their age to 19 in 2021. Vermont even updated its law in 2022 to include people under 20. However, three states like Texas and Georgia still use age 17. Japan also changed its laws on April 1, 2022. They lowered the age of minor status from under 20 to under 18.
Many things can influence why a young person breaks the law. Family life and friends are two very big factors. For example, the way parents discipline a child matters a lot. Researchers study different parenting styles, like being warm and supportive. Some kids might also join groups that lead to bad choices. Peer rejection can also make a child feel lonely or angry. These social connections play a huge role in how kids grow up.
It is also helpful to look at how society is built. Some experts talk about the school-to-prison pipeline. This is the idea that more jails are built than colleges in many states. In the U.S., youth violence has actually dropped a lot since 1993. This shows that most young crime is not violent. Instead of just punishment, some people suggest using restorative justice. This approach focuses on making things right and helping people change.
Juvenile delinquency, or juvenile offending, describes unlawful behavior committed by individuals below the statutory age of majority. These actions are defined as crimes because they would be illegal if an adult performed them. Experts often categorize these behaviors into three distinct groups. Status offenses are actions that are only illegal because of the person's age, such as truancy or underage drinking. Criminal behavior involves crimes handled by the adult criminal justice system. Finally, delinquency refers to offenses specifically handled by the juvenile justice system.

The history of how society treats young offenders has changed significantly. Before the 18th century, children as young as seven were tried in adult criminal courts. These children could even face the death penalty for their convictions. This changed when Illinois established the first juvenile court. This specialized court shifted the focus from punishment to treatment objectives. It also ensured that juvenile records remained confidential to protect the young people involved.
Legal definitions of age vary widely across different regions. In the United States, most states define a juvenile as someone under 18. However, some states have recently raised this limit. In 2021, Michigan, New York, and Vermont raised the age to under 19. Vermont updated its law again in 2022 to include those under 20. Conversely, Georgia, Texas, and Wisconsin still define juveniles as those under 17. Japan also adjusted its laws on April 1, 2022. The Japanese Diet lowered the age of minor status from under 20 to under 18.
Minimum ages for criminal responsibility also differ by location. Some states have recently increased the minimum age for children. For example, North Carolina moved its minimum age from 6 to 10 in 2021. Connecticut also moved from 7 to 10 years old that same year. New York adjusted its minimum age from 7 to 12. In certain jurisdictions, the minimum age depends on the specific seriousness of the crime. These varying laws reflect different approaches to how much responsibility a child holds.
Researchers study various factors that contribute to delinquent behavior. Many scholars look at environmental influences like family behavior and peer pressure. One studied concept is the school-to-prison pipeline. This describes how certain policies may lead students toward the justice system. In nearly 75% of U.S. states, more jails and prisons have been built than colleges. This focus on punitive punishment is often contrasted with restorative justice. Restorative justice focuses on repairing harm rather than just issuing punishment.
Developmental research by Moffitt (2006) identifies two specific types of offenders. The first is the adolescence-limited offender. This person begins and ends their delinquent behavior during their teenage years. Most teenagers show some form of antisocial behavior during this time. The second type is the life-course-persistent offender. These individuals begin showing aggressive or antisocial behavior in childhood or adolescence. They continue this pattern of offending well into their adult lives.
Family dynamics and parenting styles are also significant predictors of behavior. Researchers identify four main categories of parenting. Authoritative parenting combines warmth and support with clear discipline. Indulgent parenting offers warmth but lacks structure or discipline. Authoritarian parenting provides high discipline but lacks warmth. Finally, neglectful parenting is both non-responsive and non-demanding. Studies suggest that the authoritative style is most beneficial for healthy development.
Peer influence and social rejection also play major roles in adolescence. Peer rejection in childhood can lead a person to join antisocial groups. These groups may promote violent or deviant behavior. Some adolescents may join gangs to find protection or resources. Other situational factors, such as changes in the weather, have even been linked to deviant behavior. Understanding these complex social, familial, and legal layers helps experts study juvenile delinquency more deeply.
