Youth work is community support activity aimed at older children and adolescents. Depending upon the culture and the community, different services and institutions may exist for this purpose. In the United Kingdom youth work is the process of creating an environment where young people can engage in informal educational activities. Different varieties of youth work include centre-based work, detached work, school-based work and religion based work. Throughout the United States and Canada, youth work is any activity that seeks to engage young people in coordinated programs, including those that are recreational, educational, or social by nature and design. "Youth work" is defined as activities that intentionally seek to impact young people. This is primarily a set of loosely affiliated activities that have been defined, redefined, examined, and reinvented in subsequent generations. In Ireland the Youth Work Act of 2001 states that, "'Youth work' means a planned programme of education designed for the purpose of aiding and enhancing the personal and social development of young persons through their voluntary participation, and which (a) complements their formal, academic, or vocational education and training; and (b) is provided primarily by voluntary youth work organisations." However, critics of this particular definition report that, "This definition sees youth work primarily in terms of the development of the young person. However some would argue that this is a limited view and that central to a definition of youth work is the notion that youth work should aim to engage with society and bring about social change in an unequal society." These same critics report that youth work should seek "real Youth participation liberation and youth empowerment Youth work is historically said to focus on five areas, including a focus on young people; an emphasis on voluntary participation and relationship; a commitment to association by youth and adults; friendly and informal atmospheres, and; acting with integrity.
