I’m a little confused by the “not in universe” labeling - in particular how it might differ from missing values. I used the IPUMS-DHS website to pull several West African countries’ women surveys over several years and I have several variables with a “not in universe” label along with missing values.
I’m kind of assuming that “not in universe” simply means that the question didn’t apply to that woman? For instance, the variable DELDOC_01 being equal to “not in universe” simply means that that woman didn’t give birth in the last three to five years, because if she did she could have answered in either the positive or negative to having some kind of medical professional deliver the previous baby. However, assuming that my assumption is right, how do these women differ from the missing values? Or am I just completely off base and have no idea?
Thank you in advance for your reply.
