Hi, I wonder if there is a typo for the universe of "ethid4a" variable in wave 5.
The online documentation says the variable was collected for those who satisfy other conditions plus ff_newimm=1.
I could not find the variable ff_newimm but e_newimm from e_indall dataset.
So I wonder if the online documentation includes a typo/ there exists a variable 'ff_newimm' that I can not find.
Also, I wonder how the recent immigrant was defined, for instance, does it includes the new immigrants for the given wave or does it include those who immigrated since wave 1.
