Update, March 2020
We will maintain the dual mappings until further notice. We will re-evaluate when or if the BLS implements the "18-04" delineations.
Update, December 2019
We plan to apply the new CBSA delineations to our metro forecast model with its March 2020 vintage, to coincide with the BLS's schedule. To avoid any confusion, we will apply the changes to the ZIP Code mapping file at the same time.
Original article
The OMB CBSA definitions are subject to change (“vintages” or “delineations”), sometimes more than once per year. Moody’s Analytics has found it necessary to maintain distinct sets of geo codes specific to each vintage, so as to record old datasets that used prior vintages, active datasets that use different vintages, and our metro area forecasts.
We maintain a collection of mapping files (i.e., concordance spreadsheets) as a Zipped file, distributed via the Reference Files section of Data Buffet. The latest version of the collection (published in August) contains a new “beta” format, which we will deploy in 2020; it also contains the previous format, which (at client request) we will update in parallel until 2020. The difference is that the previous format relates each ZIP Code to three successive CBSA delineations, whereas the "beta" format is streamlined to the active delineation.
