TREE (Transitions from Education to Employment) is a large national panel survey following up compulsory school leavers from all over Switzerland through their post-compulsory education and training and into employment and adulthood. Observation of the first TREE cohort (TREE1) started in 2000. To date, ten follow-up surveys have been conducted. In 2014, survey participants were, on average, 30 years old.
By means of dumbbell plots, the visualisation displays the development of the various subgroups' average monthly gross income throughout the period of observation (2003-2014). The blue plots show the nominal income, the orange plots represent full time equivalents (FTE). Placing the cursor on any one of the blue or orange arrows will display the income development curve of the respective subgroup. Placing the cursor on any of the data points of the curve will a tooltip will provide you with its numeric value and the number of cases on which the value is based. If the number of cases is below 30, the numeric value is displayed in red in order to signal limited accuracy of the average's estimation. Please not that the calculation only accounts for individuals who were not in education parallel to their gainful activity.
