The working student rate is the number of student who work while studying divided by youth population at the district level, province level, and national level. Some years may use different definitions of working student. These distinct definitions are described below:

In 2020, the working student population includes those who have been working in the last week at least one hour non-stop, or who running their business, or who helping relatives business, or those who are temporarily not working and those who still studying at school.

From 2016 until 2019, the working student population includes those who have been working in the last week at least one hour non-stop, or who running their business, or who helping relatives business, or those who are temporarily not working and those who have been studying in the last week.

From 1997 until 2015, The employed population includes those who have been working in the last week at least one hour non-stop, or those who are temporarily not working and those who have been studying in the last week.

In 1993, 1994. and 1996 The employed population includes those who have been working in the last week at least one hour non-stop, or those who are temporarily not working, and those who still studying at school.

The definition of youth population has been unchanged since 1993 until 2020, we define youth population as a person aged between 15 years old and 24 years old.

These data are collected from The National Labor Force Survey (Sakernas) module from 1993-2020, except for 1995 because there was no survey in that particular year, and 2016, because only province level is available.
