Youth is the time of life when one is young, but 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; like voting age, age of candidacy, age of consent, age of majority,drinking age, driving age, etc. After youth reach these limits they are free to vote, have intercourses, buy alcohol beverages or drive cars, also they can be criminal responsible of they actions; nor can its end point be linked to specific activities, such as taking unpaid work or having sexual relations without consent.[4]
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.[4]
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.[9]
While recognizing that member states use different chronologies to define youth, 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 theses 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.[4] 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.
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]
Youth is the stage of constructing the self-concept. The self-concept of youth is influenced by several variables such as peers, lifestyle, gender, and culture.[13] It is the time of a person's life in which they make choices which will affect their future.[14]
In much of sub-Saharan Africa, the term "youth" is associated with young men from 15 to 30 or even 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 or 18 to 25 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]
August 12 was declared International Youth Day by the United Nations.

Children's rights cover all the rights that belongs to children, when they grow up are granted with new rights (like voting, consent, driving, etc) and duties (criminal response, etc). There are different minimum limits of age at wich youth are not free, independent or legally competent to take some decitions or actions, some of 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 intercourses, buy or consume alcohol beverages or drive cars, etc.
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 they can vote and support politics selected by them and not by older generations.
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 to be 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.
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. After reaching the initial age, there may be levels of responsibility dictated by age and the type of offense committed.
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.[17]
Driving age is the age at wich a person can apply for a driver's license. Countries with the lowest driving ages (below 17) are Australia, Canada, El Salvador, Iceland, Israel, India, 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.
The legal working age is the minimum age required by law for a person to work, in each country or jurisdiction. 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 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.
Youth have rights and also responsibilities that comes with their ages, one of them is age of criminal responsibility, after reaching the initial age, there may be levels of responsibility dictated by age and the type of offense committed.
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.[4] 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.[18]
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 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.[19]
The U.S. Centers for Disease Control and Prevention developed its Youth Risk Behavior Surveillance System (YRBSS) in 2003 to help assess risk behavior.[20] YRBSS monitors six categories of priority health-risk behaviors among youth and young adults:
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.[21]
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. Because obese children tend to be taller than their non-overweight peers, 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.[22]
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.[23][24][25][26]
The majority of research on bullying has been conducted in Europe and Australia. 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.[27][28] 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.[29][30][31][32][33][34]
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.[35][36][37][38]
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'.[39] 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 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.[40]
The Sangguniang Kabataan ("Youth Council" in English), commonly known as SK, was a youth council in each barangay in the Philippines, before being put "on hold", but not quite abolished, prior to the 2013 barangay elections.[41] 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.
The vast majority of young people live in developing countries: according to the UN, globally around 85 per cent of 15- to 24-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, Asia and South America, some live traditional lives in tribal societies, while others participate in global youth culture in ghetto contexts.[4]
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.[4]
