I have a question on the ACS PROPTX99 variable:
The code list is here but I could not find any info on how the N/A code (PROPTX99 == 00) was assigned (neither in the description nor the editing procedure tab).
I looked into this a bit and found that all renters (OWNERSHP == 2) have PROPTX99 == N/A but there are additional N/As which are not explained by ownership status.
Is there some additional documentation on the N/A assignment available? E.g. what other variables were used in the assignment? Does it mean ‘missing’ in some records? How does it compare to NIU? (I am mostly interested in the years 2005 and 2006.)
Many thanks for helping with this!
