If you want to pinpoint a specific item or variable, you can search for it by typing the keyword or variable name (e.g. Q1) in the search windowin the sidebar.
Note that, in principle, variable names are changed when the question is the same, but the wording of the question or the code of the choices is changed. For example, in the second survey, changes were made to the Working status
option regarding the respondents themselves, so the variable names were also changed.
For items where the variable name of the item has been changed in this way, we have, in principle, provided a page explaining the change in the variable name, but it is not yet completely comprehensive at this stage. You can check “how many surveys include the variable you are using in the data” from the first survey in the Recording Sheets section of each variable’s page.
