Youth is the time of life when one is young, and often means the time between childhood and adulthood (maturity). [1] [2] It is also defined as "the appearance, freshness, vigor, spirit, etc., characteristic of one who is young". [3] Its definitions of a specific age range varies, as youth is not defined chronologically as a stage that can be tied to specific age ranges; nor can its end point be linked to specific activities, such as taking unpaid work or having sexual relations without consent. [4]

Childhood age from birth to adolescence

Childhood is the age span ranging from birth to adolescence. According to Piaget's theory of cognitive development, childhood consists of two stages: preoperational stage and concrete operational stage. In developmental psychology, childhood is divided up into the developmental stages of toddlerhood, early childhood, middle childhood, and adolescence. Various childhood factors could affect a person's attitude formation.

Biologically, an adult is a human or other organism that has reached sexual maturity. In human context, the term adult additionally has meanings associated with social and legal concepts. In contrast to a "minor", a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and responsible. The typical age of attaining legal adulthood is 18, although definition may vary by legal rights and country.

In psychology, maturity is the ability to respond to the environment aware of the correct time and location to behave and knowing when to act, according to the circumstances and the culture of the society one lives in. Adult development and maturity theories include the purpose in life concept, in which maturity emphasizes a clear comprehension of life's purpose, directedness, and intentionality, which contributes to the feeling that life is meaningful.


Youth is an experience that may shape an individual's level of dependency, which can be marked in various ways according to different cultural perspectives. Personal experience is marked by an individual's cultural norms or traditions, while a youth's level of dependency means the extent to which they still rely on their family emotionally and economically.

Around the world, the English terms youth, adolescent , teenager, kid, and young person are interchanged, often meaning the same thing, [5] but they are occasionally differentiated. Youth can be referred to as the time of life when one is young. This involves childhood, and the time of life which is neither childhood nor adulthood, but rather somewhere in between. [6] [7] Youth also identifies a particular mindset of attitude, as in "He is very youthful". For certain uses, such as employment statistics, the term also sometimes refers to individuals from the ages of 14 to 21. [8] However, the term adolescence refers to a specific age range during a specific developmental period in a person's life, unlike youth which is a socially constructed category. [4]

English language West Germanic language

English is a West Germanic language that was first spoken in early medieval England and eventually became a global lingua franca. It is named after the Angles, one of the Germanic tribes that migrated to the area of Great Britain that later took their name, as England. Both names derive from Anglia, a peninsula in the Baltic Sea. The language is closely related to Frisian and Low Saxon, and its vocabulary has been significantly influenced by other Germanic languages, particularly Norse, and to a greater extent by Latin and French.

Adolescence transitional stage of physical and psychological development that generally occurs during the period from puberty to legal adulthood

Adolescence is a transitional stage of physical and psychological development that generally occurs during the period from puberty to legal adulthood. Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier and end later. For example, puberty now typically begins during preadolescence, particularly in females. Physical growth and cognitive development can extend into the early twenties. Thus, age provides only a rough marker of adolescence, and scholars have found it difficult to agree upon a precise definition of adolescence.

The United Nations defines youth as persons between the ages of 15 and 24 with all UN statistics based on this range, the UN states education as a source for these statistics. The UN also recognizes that this varies without prejudice to other age groups listed by member states such as 18–30. A useful distinction within the UN itself can be made between teenagers (i.e. those between the ages of 13 and 19) and young adults (those between the ages of 18 and 32). While seeking to impose some uniformity on statistical approaches, the UN itself is aware of contradictions between approaches in its own statutes. Hence under the 15–24 definition (introduced in 1981) children are defined as those under the age of 14 while under the 1979 Convention on the Rights of the Child, those under the age of 18 are regarded as children. [9] The UN also states they are aware that several definitions exist for youth within UN entities such as Youth Habitat 15–32 and African Youth Charter 15–35.

United Nations Intergovernmental organization

The United Nations (UN) is an intergovernmental organization tasked with maintaining international peace and security, developing friendly relations among nations, achieving international co-operation, and being a centre for harmonizing the actions of nations. It was established after World War II, with the aim of preventing future wars, and succeeded the ineffective League of Nations. Its headquarters, which are subject to extraterritoriality, are in Manhattan, New York City, and it has other main offices in Geneva, Nairobi, Vienna and The Hague. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, protecting human rights, delivering humanitarian aid, promoting sustainable development, and upholding international law. The UN is the largest, most familiar, most internationally represented and most powerful intergovernmental organization in the world. At its founding, the UN had 51 member states; there are now 193.

Although linked to biological processes of development and aging, youth is also defined as a social position that reflects the meanings different cultures and societies give to individuals between childhood and adulthood. The term in itself when referred to in a manner of social position, can be ambiguous when applied to someone of an older age with very low social position; potentially when still dependent on their guardians. [10] Scholars argue that age-based definitions have not been consistent across cultures or times and that thus it is more accurate to focus on social processes in the transition to adult independence for defining youth. [11]

Social position is the position of an individual in a given society and culture. A given position may belong to many individuals. Social position influences social status.

"This world demands the qualities of youth: not a time of life but a state of mind, a temper of the will, a quality of imagination, a predominance of courage over timidity, of the appetite for adventure over the life of ease." – Robert Kennedy [12]

Youth is the stage of constructing the self-concept. The self-concept of youth is influenced by variables such as peers, lifestyle, gender, and culture. [13] It is a time of a person's life when their choices are most likely to affect their future. [14]

Self-concept ones internal description of oneself

One's self-concept is a collection of beliefs about oneself. Generally, self-concept embodies the answer to "Who am I?".

Other definitions

In much of sub-Saharan Africa, the term "youth" is associated with young men from 15 to 30 or 35 years of age. Youth in Nigeria includes all members of the Federal Republic of Nigeria aged 18–35. [15] Many African girls experience youth as a brief interlude between the onset of puberty and marriage and motherhood. But in urban settings, poor women are often considered youth much longer, even if they bear children outside of marriage. Varying culturally, the gender constructions of youth in Latin America and Southeast Asia differ from those of sub-Saharan Africa. In Vietnam, widespread notions of youth are sociopolitical constructions for both sexes between the ages of 15 and 35. [16]

In Brazil, the term youth refers to people of both sexes from 15 to 29 years old. This age bracket reflects the influence on Brazilian law of international organizations like the World Health Organization (WHO). It is also shaped by the notion of adolescence that has entered everyday life in Brazil through a discourse on children's rights. [16]

The intergovernmental organization Organisation for Economic Co-operation and Development defines youth as "those between 15 and 29 years of age". [17] [18]

August 12 was declared International Youth Day by the United Nations.

Youth rights

Children's rights cover all the rights that belong to children. When they grow up they are granted with new rights (like voting, consent, driving, etc.) and duties (criminal response, etc.). There are different minimum limits of age at which youth are not free, independent or legally competent to take some decisions or actions. Some of these limits are voting age, age of candidacy, age of consent, age of majority, age of criminal responsibility, drinking age, driving age, etc. After youth reach these limits they are free to vote, have sexual intercourse, buy or consume alcohol beverages or drive cars, etc.

Voting age

Voting age is the minimum age established by law that a person must attain to be eligible to vote in a public election. Typically, the age is set at 18 years; however, ages as low as 16 and as high as 21 exist (see list below). Studies show that 21% of all 18 year olds have experience with voting. This is an important right since, by voting they can support politics selected by themselves and not only by people of older generations.

Age of candidacy

Age of candidacy is the minimum age at which a person can legally qualify to hold certain elected government offices. In many cases, it also determines the age at which a person may be eligible to stand for an election or be granted ballot access.

The age of consent is the age at which a person is considered legally competent to consent to sexual acts, and is thus the minimum age of a person with whom another person is legally permitted to engage in sexual activity. The distinguishing aspect of the age of consent laws is that the person below the minimum age is regarded as the victim, and their sex partner as the offender.

Defense of infancy

The defense of infancy is a form of defense known as an excuse so that defendants falling within the definition of an "infant" are excluded from criminal liability for their actions, if at the relevant time, they had not reached an age of criminal responsibility. This implies that children lack the judgment that comes with age and experience to be held criminally responsible. After reaching the initial age, there may be levels of responsibility dictated by age and the type of offense committed.

Drinking age

The legal drinking age is the age at which a person can consume or purchase alcoholic beverages. These laws cover a wide range of issues and behaviors, addressing when and where alcohol can be consumed. The minimum age alcohol can be legally consumed can be different from the age when it can be purchased in some countries. These laws vary among different countries and many laws have exemptions or special circumstances. Most laws apply only to drinking alcohol in public places, with alcohol consumption in the home being mostly unregulated (an exception being the UK, which has a minimum legal age of five for supervised consumption in private places). Some countries also have different age limits for different types of alcoholic drinks. [19]

Driving age

Driving age is the age at which a person can apply for a driver's license. Countries with the lowest driving ages (below 17) are Australia, Canada, El Salvador, Iceland, Israel, Estonia, Macedonia, Malaysia, New Zealand, Norway, the Philippines, Russia, Saudi Arabia, Slovenia, Sweden, the United Kingdom (Mainland) and United States. The Canadian province of Alberta and several U.S. states permit youth driving as low as 14. Niger has the highest minimum driving age in the world at 23. In India, driving is legal after getting a license at the age of 18.

The legal working age is the minimum age required by law for a person to work, in each country or jurisdiction. The threshold of adulthood, or "the age of majority" as recognized or declared in law in most countries has been set at age 18. Some types of labor are commonly prohibited even for those above the working age, if they have not reached yet the age of majority. Activities that are dangerous, harmful to the health or that may affect the morals of minors fall into this category.

Student rights in higher education

Student rights are those rights, such as civil, constitutional, contractual and consumer rights, which regulate student rights and freedoms and allow students to make use of their educational investment. These include such things as the right to free speech and association, to due process, equality, autonomy, safety and privacy, and accountability in contracts and advertising, which regulate the treatment of students by teachers and administrators.

Smoking age

The smoking age is the minimum age a person can buy tobacco, and/or smoke in public. Most countries regulate this law at the national level while at some it is done by the state or province.

Socioeconomic issues

The growth of youth unemployment, which reached new heights of 22.5% across the European Union, as well as the precarisation of labor market conditions reveals that the gap between labor market 'outsiders' and 'insiders' is widening. One of the most dramatic possible consequences of this growing divergence could arguably be the disenfranchisement of labour market outsiders, especially young people, from social and political participation (Ferragina et al. 2016). [20] If the objective of policymakers is to revive social and political participation in a period of great disenchantment and declining legitimacy for our democracies, there is definitely scope for further enquiry and action into the effects of youth outsiderness on social and political participation.

School and education

Young people spend much of their lives in educational settings, and their experiences in schools, colleges and universities can shape much of their subsequent lives. [21] Research shows that poverty and income affect the likelihood for the incompletion of high school. These factors also increase the likelihood for the youth to not go to a college or university. [22] In the United States, 12.3 percent of young people ages 16 to 24 are disconnected, meaning they are neither in school nor working. [23]

Health and mortality

The leading causes of morbidity and mortality among youth and adults are due to certain health-risk behaviors. These behaviors are often established during youth and extend into adulthood. Since the risk behaviors in adulthood and youth are interrelated, problems in adulthood are preventable by influencing youth behavior.

A 2004 mortality study of youth (defined in this study as ages 10–24) mortality worldwide found that 97% of deaths occurred in low to middle-income countries, with the majority in southeast Asia and sub-Saharan Africa. Maternal conditions accounted for 15% of female deaths, while HIV/AIDS and tuberculosis were responsible for 11% of deaths; 14% of male and 5% of female deaths were attributed to traffic accidents, the largest cause overall. Violence accounted for 12% of male deaths. Suicide was the cause of 6% of all deaths. [24]

The U.S. Centers for Disease Control and Prevention developed its Youth Risk Behavior Surveillance System (YRBSS) in 2003 to help assess risk behavior. [25] YRBSS monitors six categories of priority health-risk behaviors among youth and young adults. These are behaviors that contribute to unintentional injuries and violence;

YRBSS includes a national school-based survey conducted by CDC as well as state and local school-based surveys conducted by education and health agencies. [26]


Obesity now affects one in five children in the United States, and is the most prevalent nutritional disease of children and adolescents in the United States. Although obesity-associated morbidities occur more frequently in adults, significant consequences of obesity as well as the antecedents of adult disease occur in obese children and adolescents.

Discrimination against overweight children begins early in childhood and becomes progressively institutionalized. Obese children may be taller than their non-overweight peers, in which case they are apt to be viewed as more mature. The inappropriate expectations that result may have an adverse effect on their socialization.

Many of the cardiovascular consequences that characterize adult-onset obesity are preceded by abnormalities that begin in childhood. Hyperlipidemia, hypertension, and abnormal glucose tolerance occur with increased frequency in obese children and adolescents. The relationship of cardiovascular risk factors to visceral fat independent of total body fat remains unclear. Sleep apnea, pseudotumor cerebri, and Blount's disease represent major sources of morbidity for which rapid and sustained weight reduction is essential. Although several periods of increased risk appear in childhood, it is not clear whether obesity with onset early in childhood carries a greater risk of adult morbidity and mortality. [27]


Bullying among school-aged youth is increasingly being recognized as an important problem affecting well-being and social functioning. While a certain amount of conflict and harassment is typical of youth peer relations, bullying presents a potentially more serious threat to healthy youth development. The definition of bullying is widely agreed on in literature on bullying. [28] [29] [30] [31]

The majority of research on bullying has been conducted in Europe and Australia.[ citation needed ] Considerable variability among countries in the prevalence of bullying has been reported. In an international survey of adolescent health-related behaviors, the percentage of students who reported being bullied at least once during the current term ranged from a low of 15% to 20% in some countries to a high of 70% in others. [32] [33] Of particular concern is frequent bullying, typically defined as bullying that occurs once a week or more. The prevalence of frequent bullying reported internationally ranges from a low of 1.9% among one Irish sample to a high of 19% in a Malta study. [34] [35] [36] [37] [38] [39]

Research examining characteristics of youth involved in bullying has consistently found that both bullies and those bullied demonstrate poorer psychosocial functioning than their non-involved peers. Youth who bully others tend to demonstrate higher levels of conduct problems and dislike of school, whereas youth who are bullied generally show higher levels of insecurity, anxiety, depression, loneliness, unhappiness, physical and mental symptoms, and low self-esteem. Males who are bullied also tend to be physically weaker than males in general. The few studies that have examined the characteristics of youth who both bully and are bullied found that these individuals exhibit the poorest psychosocial functioning overall. [40] [41] [42] [43]

Sexual health and politics


Globalization and transnational flows have had tangible effects on sexual relations, identities, and subjectivities. In the wake of an increasingly globalized world order under waning Western dominance, within ideologies of modernity, civilization, and programs for social improvement, discourses on population control, 'safe sex', and 'sexual rights'. [44] Sex education programmes grounded in evidence-based approaches are a cornerstone in reducing adolescent sexual risk behaviours and promoting sexual health. In addition to providing accurate information about consequences of Sexually transmitted disease or STIs and early pregnancy, such programmes build life skills for interpersonal communication and decision making. Such programmes are most commonly implemented in schools, which reach large numbers of teenagers in areas where school enrollment rates are high. However, since not all young people are in school, sex education programmes have also been implemented in clinics, juvenile detention centers and youth-oriented community agencies. Notably, some programmes have been found to reduce risky sexual behaviours when implemented in both school and community settings with only minor modifications to the curricula. [45]


The Sangguniang Kabataan ("Youth Council" in English), commonly known as SK, was a youth council in each barangay (village or district) in the Philippines, before being put "on hold", but not quite abolished, prior to the 2013 barangay elections. [46] The council represented teenagers from 15 to 17 years old who have resided in their barangay for at least six months and registered to vote. It was the local youth legislature in the village and therefore led the local youth program and projects of the government. The Sangguniang Kabataan was an offshoot of the KB or the Kabataang Barangay (Village Youth) which was abolished when the Local Government Code of 1991 was enacted.

In the Global South

The vast majority of young people live in developing countries: according to the UN, globally around 85 per cent of 15- to 25-year-olds live in developing countries, a figure projected to grow 89.5 per cent by 2025. Moreover, this majority are extremely diverse: some live in rural areas but many inhabit the overcrowded metropolises of India, Mongolia and other parts of Asia and in South America, some live traditional lives in tribal societies, while others participate in global youth culture in ghetto contexts. [47]

Many young lives in developing countries are defined by poverty, some suffer from famine and a lack of clean water, while involvement in armed conflict is all common. Health problems are rife, especially due to the prevalence of HIV/AIDS in certain regions. The United Nations estimates that 200 million young people live in poverty, 130 million are illiterate and 10 million live with HIV/AIDS. [47]

Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as "antisocial behaviors." It is often seen as the precursor to antisocial personality disorder, which is per definition not diagnosed until the individual is 18 years old.

Bullying Use of force or coercion to abuse or intimidate others

Bullying is the use of coercion, force, or threat, to abuse, aggressively dominate or intimidate. The behavior is often repeated and habitual. One essential prerequisite is the perception of an imbalance of physical or social power. This imbalance distinguishes bullying from conflict. There is no universal definition of bullying. It is widely agreed upon that bullying is a subcategory of aggressive behavior characterized by the following three minimum criteria: (1) hostile intent, (2) imbalance of power, and (3) repetition over a period of time. Bullying may thus be defined as the activity of repeated, aggressive behavior intended to hurt another individual, physically, mentally, or emotionally.

Anti-social behaviours are actions that harm or lack consideration for the well-being of others. It has also been defined as any type of conduct that violates the basic rights of another person and any behaviour that is considered to be disruptive to others in society. This can be carried out in various ways, which includes but is not limited to intentional aggression, as well as covert and overt hostility. Anti-social behaviour also develops through social interaction within the family and community. It continuously affects a child's temperament, cognitive ability and their involvement with negative peers, dramatically affecting children's problem solving skills. Many people also label behaviour which is deemed contrary to prevailing norms for social conduct as anti-social behaviour. However, researchers have stated that it is a difficult term to define, particularly in the United Kingdom where there are an infinite number of acts that fall into its category. The term is especially used in British English.

Relational aggression or alternative aggression is a type of aggression in which harm is caused by damaging someone's relationships or social status. Although it can be used in many contexts and among different age groups, relational aggression among adolescents in particular, has received a lot of attention.

Childhood obesity condition where excess body fat negatively affects a childs health or well-being

Childhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term overweight rather than obese is often used when discussing childhood obesity, especially in open discussion, as it is less stigmatizing.

Adolescent health, or youth health, is the range of approaches to preventing, detecting or treating young people’s health and well being.

Youth suicide is when a young person, generally categorized as someone below age 21, deliberately ends their own life. Rates of attempted and completed youth suicide in Western societies and other countries are high. Youth suicide attempts are more common among girls, but adolescent males are the ones who usually carry out suicide. Suicide rates in youths have nearly tripled between the 1960s and 1980s. For example, in Australia suicide is second only to motor vehicle accidents as its leading cause of death for people aged 15–25, and according to the National Institute for Mental Health, suicide is the third leading cause of death among teens in the United States.

Obesity in the United States is a major health issue, resulting in numerous diseases, specifically increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, as well as significant increase in early mortality and economic costs. While many industrialized countries have experienced similar increases, obesity rates in the United States are the highest in the world.

Cognitive epidemiology is a field of research that examines the associations between intelligence test scores and health, more specifically morbidity and mortality. Typically, test scores are obtained at an early age, and compared to later morbidity and mortality. In addition to exploring and establishing these associations, cognitive epidemiology seeks to understand causal relationships between intelligence and health outcomes. Researchers in the field argue that intelligence measured at an early age is an important predictor of later health and mortality differences.

Depression is a state of low mood and aversion to activity. It may be a normal reaction to occurring life events or circumstances, a symptom of a medical condition, a side effect of drugs or medical treatments, or a symptom of certain psychiatric syndromes, such as the mood disorders major depressive disorder and dysthymia. Depression in childhood and adolescence is similar to adult major depressive disorder, although young sufferers may exhibit increased irritability or aggressive and self-destructive behavior, rather than the all-encompassing sadness associated with adult forms of depression. Children who are under stress, experience loss, or have attention, learning, behavioral, or anxiety disorders are at a higher risk for depression. Childhood depression is often comorbid with mental disorders outside of other mood disorders; most commonly anxiety disorder and conduct disorder. Depression also tends to run in families. Psychologists have developed different treatments to assist children and adolescents suffering from depression, though the legitimacy of the diagnosis of childhood depression as a psychiatric disorder, as well as the efficacy of various methods of assessment and treatment, remains controversial.

Research has found that attempted suicide rates and suicidal ideation among lesbian, gay, bisexual, and transgender (LGBT) youth is significantly higher than among the general population. LGBT adolescents have the highest rate of suicide attempts, which scientific research indicates is linked to homophobic attitudes and heterosexist discrimination.

The social stigma of obesity or anti-fat bias has resulted in additional difficulties and disadvantages for overweight and obese people. Weight stigma is similar and has been broadly defined as bias or discriminatory behaviors targeted at individuals, because of their weight. Such social stigmas can span one's entire life, as long as excess weight is present, starting from a young age and lasting into adulthood. Several studies from across the world indicate overweight and obese individuals experience higher levels of stigma relative to their thinner counterparts. In addition, they marry less often, experience fewer educational and career opportunities, and on average earn a lesser income than normal weight individuals. Although public support regarding disability services, civil rights and anti-workplace discrimination laws for obese individuals have gained support across the years, overweight and obese individuals still experience discrimination, which may have implications to physiological and psychological health. These issues are compounded with the significant negative physiological effects associated with obesity.

Cyberbullying or cyberharassment is a form of bullying or harassment using electronic means. Cyberbullying and cyberharassment are also known as online bullying. It has become increasingly common, especially among teenagers. Cyberbullying is when someone, typically teens, bully or harass others on the internet, particularly on social media sites. Harmful bullying behavior can include posting rumors, threats, sexual remarks, a victims' personal information, or pejorative labels. Bullying or harassment can be identified by repeated behavior and an intent to harm. Victims may experience lower self-esteem, increased suicidal ideation, and a variety of negative emotional responses, including being scared, frustrated, angry, and depressed.

Children and adolescents in the United States can be regarded as one age group in the demographics of the United States.

Childhood obesity is defined as a body mass index (BMI) at or above the 96th percentile for children of the same age and sex. It can cause a variety of health problems, including high blood pressure, high cholesterol, heart disease, diabetes, breathing problems, sleeping problems, and joint problems later in life. Children who are obese are at a greater risk for social and psychological problems as well, such as peer victimization, increased levels of aggression, and low self-esteem. Many environmental and social factors have been shown to correlate with childhood obesity, and researchers are attempting to use this knowledge to help prevent and treat the condition. When implemented early, certain forms of behavioral and psychological treatment can help children regain and/or maintain a healthy weight.

Alcohol is a liquid form substance which contains ethyl alcohol that can cause harm and even damage to a persons DNA. "Alcohol consumption is recognized worldwide as a leading risk factor for disease, disability, and death." and is rated as the most used and abused substance by adolescences. Adolescence is a transitional stage of physical and psychological changes, usually a time in a person life in which they go through puberty. Combining these transitional stages and the intake of alcohol, can leave a number of consequences for an adolescent.
