Youth Transition in a Globalized Marketplace (YTGM) is based on the experiences of youth in a number of countries. The authors of this study are internationally recognised as leaders in the field of youth research. It deals with the increasingly complex question of youth transition. As Miles observes: "...a key term in developing any adequate understanding of young people's lifestyles is that of 'transition', the process by which young people somehow manage to reach 'adulthood'." Galland proposes a model called the 'crossing of thresholds' that define the pattern and progress of transition to adulthood. He suggests four centrally important thresholds that define the pattern and progress of transition to adulthood. These he defines as completing education/training, entry to employment, leaving home and forming a couple.
