Code for principal cities, post 2015

There are 86 unique combinations of METFIPS and INDIVIDCC in CPS data published from 2016 to the present (2021).

The most current documentation I could find for the codes for individual principal cities only lists 74 cities (and 68 unique METFIPS and INDIVIDCC combinations. That documentation also includes METFIPS code that have been out of date since 2014-2015.

Is there any more recent documentation for interpreting INDIVIDCC codes?

Looking at the original CPS codebooks, they have listings for the principal cities.

I apologize for the delayed response. You are correct that the documentation is out of date and that the updated principal cities are detailed in the CPS codebooks. The IPUMS CPS team is aware of this and are looking into updating the documentation.
