Why did Bert drop out? Originally published in 1954, the answer forms the substance of , the report of an inquiry into adolescents’ reactions to their local youth groups. Besides answering the question "Who joins what?" (and two thirds of these thousand youngsters of 14 to 17 were not members of any youth organisation) the book describes some of the hopes, pleasures and difficulties of such people as Frances, the chocolate packer, who has ambition to marry before long; and John, the carpenter’s apprentice, whose passions are autocycling, pigeons and pigs. It also throws light on problems such as those presented by gangs; and suggests the importance of "my friends," the closely-knit set who mean so much to the adolescent.
