As it happens, we recently completed our internal work to produce a new “PWMET13” variable that will supply 2013 metro area codes for 2000 and 2005-2016 samples. We plan to release the variable later this fall, in mid-October at the earliest.
Before then, you can make use of the attached supplementary files, which correspond (just as you suggested) with the MET2013 crosswalk files. I see that the User Forum system has truncated the file names, so that two of the files now have the same name (PWMET13_match_errors.xls). They both describe match errors between 2013 MSA’s and 2000 PWPUMA’s, but one uses 2000 populations (for 2000 samples) and the other uses 2010 populations (for 2005-2011 ACS samples).
Our code assignment protocol for PWMET13 will match MET2013’s: we’ll assign an MSA code to a PWPUMA if more than 50% of the PWPUMA’s population resides in the MSA _and_ the sum of omission and commission errors for the MSA is less than 15%.
If you have any more questions, feel free to reply to this post.
