In order to counteract widespread stereotyping of adolescents and to provide a historical perspective on the lives of youth in Great Britain, this report compiles statistical data in six areas regarding adolescents and youth. Chapter 1, "Population, Families and Households," presents information on the population of the United Kingdom including age distribution of various racial/ethnic groups, discusses trends in marital stability and partnerships and parenthood outside marriage, and provides information on children/youth receiving out-of-home care. Chapter 2, "Education, Training and Employment," presents information on trends in educational attainment since the early 1980s, permanent exclusions (expulsions) from school, secondary education participation, and youth employment, with regional or sex differences highlighted. Chapter 3, "Physical Health," contains information on youth mortality and its causes, reasons for consulting with a physician, youth attitudes toward primary health care services, and information on dieting, drug or alcohol use, cigarette smoking, and sports and physical activity participation. Chapter 4, "Sexual Health," presents data on trends in age at first sexual intercourse, contraception use, pregnancy, abortion, birth rates, sexually transmitted diseases, HIV, and attitudes toward sex education. Chapter 5, "Mental Health," contains data on youth suicide rates, prevalence of psychiatric disorders, bullying, child abuse, and stressors. Chapter 6, "Crime," contains information on age differences in criminal convictions, juvenile justice, reconviction rates, and types of crimes committed. (Each chapter contains references.) (KB)
