Matrix of variables vs waves
I am wondering if there is a matrix available somewhere of all the variables that ever appear in any wave of Understanding Society vs which wave exactly do they appear. Basically, similar to the grid IPUMS provides for variable selection.
I am sorry if I somehow missed this information on the website, but currently I can only see the set of variables within each wave or the set of waves for individual variables. And since there are many variables I am interested in, I am getting lost where did I see what.
Thank you in advance!
