Transitions from Education to Employment

Data

TREE ranges among Switzerland’s most important data infrastructures in the social sciences. Its data belong to the country’s most frequently used panel data sets. Several hundreds of scholars both in Switzerland and abroad have so far worked with the TREE data and published a large number of analyses based on them (see list of publications on this site).

The TREE data are basically available to all interested scholars. They are accessible online and free of charge at FORSbase (see quicklink below).

The present data release for the first TREE cohort (TREE1), published in September 2016, includes the following elements:

  • Dataset of the baseline survey (PISA 2000);
  • Wave-specific datasets of all nine survey waves carried out between 2001 and 2014;
  • A dataset containing all employment spells recorded between 2003 and 2014 on a month-by-month base. (unit of observation = spell/episode);
    this opens new research opportunities, as the employment spells can be linked and analysed both at single-spell level and at respondents’ level;
  • A dataset containing the totality of all educational diplomas the TREE respondents have obtained up to 2014;
  • A weighting dataset allowing for correction of sample bias/attrition.

A further (10th) survey wave among the 1st TREE cohort is carried out in 2019, at average respondent’s age of 35. The respective data should be available by 2021.
A first release of the data for the 2nd TREE cohort (TREE2) is scheduled to be published by 2020.
