Respondents are re-interviewed each successive year Those who leave the originally sampled household to form new households are followed up – all adult members in the new household are interviewed New members joining sample households become eligible for interview Children aged 11-15 complete a short interview (since 1994), full as they reach the age of 16 – Spare time, computer use, family relationships, health behaviour, perceptions of self, attitudes, paid work
