My present task is to create extract(s) from IHIS spanning the early seventies through the present including all variables available from a list of over 500 variables we are looking for. I spent a few hours selecting all necessary variables, then selected all samples. Unfortunately, this reduced my variable list from >500 to only 54, seemingly due to availability restrictions (i.e. if one or more years doesn’t have a variable then it is dropped entirely instead of just being left unfilled). This was very dissappointing.
Is there a way to save a list of variables to reuse? Is there a sample year that has ALL variables so I could create one extract on that year and then change the sample in subsequent revisions (perhaps 2010)? I’m trying to find a way to get the data I need without creating separate extracts for each year and having to cross-reference with my list each time. Any help would be greatly appreciated. Thanks.
