The sample attrition over time was relatively low: 89%
responded to the first survey (n=4,250) and 79% (n=3,751) to the second. The surveys contain a range of
socio-demographic and labour market information on the graduates as well as month-by-month calendar
data on their main activity. The analysis presented here will be on the 3,751 graduates who responded to
both surveys, appropriately weighted to be representative of the original sample contacted.
