2011 Internet Survey on Life and Work


In the Survey on Life and Work: 2011 Internet Survey (LOSEF 2011), we simultaneously conducted three online surveys: (1) the first obtained accurate panel data from the Annual Pension Statements, which included individual pension-participation and wage histories; (2) the second was a retrospective panel survey based on these items (job changes, marriage, childbirth, living with or apart from parents, etc.); (3) the third survey covered many aspects of life and working conditions. More information on the survey outline, survey form, and data layout is provided below.

The following depositors submit the above individual data, which are made available free of charge to researchers, educators, and government officials.
