To date the YCS covers nine cohorts and over twenty surveys. The first survey was carried out in 1985 and the most recent in 1998. The questionnaires have been designed to be broadly comparable, but external changes and shifts in policy interest, have brought about changes - some minor, some fundamental. For Cohorts one to six cohort members were contacted at yearly intervals, when they were 16-17, 17-18 and 18-19. For Cohorts 7, 8 and 9, however, the sweeps were carried out at two yearly intervals. A fourth sweep for Cohort 3 was subsequently carried out surveying cohort members at the age of 22-23.
