JGSS-2016 was conducted from the beginning of February through April 2016. The fieldwork was entrusted to the Central Research Services Inc. (Chuo-Chosa-sha).
As for JGSS conducted before, JGSS-2016 used both interview and placement (self-administered) method for each respondent.
For practical reasons the administrative order (i.e., whether to conduct the face-to-face interview before or after the questionnaire) was determined by the interviewer/ administrator depending on the circumstances of each case. In any case the administrative order was recorded for each respondent.
