Next Steps (formerly known as the Longitudinal Study of Young People in England – LSYPE) is a longitudinal study which follows a sample of around 16,000 people born in 1989/1990. Study members were recruited via schools in England when they were aged 13–14 in 2004. They were interviewed annually for seven waves until they were aged 19/20 in 2010. Co-resident parents were also interviewed in the first four waves of the study.
