I am looking for the updated ZCTA to CBSA Relationship files. I can only find one for 2010, but there is a Tiger2016 ZCTA...where is the updated relationship file? Or is there another way to find this data?


I am mapping the ZCTAs within a list of CBSAs and I have gaps caused by missing ZCTAs.

What am I missing here? enter image description here

    could you use zip codes instead? huduser.gov/portal/datasets/usps_crosswalk.html Commented Sep 17, 2016 at 2:51

    I think @AnthonyDamico should write an answer based on his comment. I don't believe that Census updates the crosswalk files for annual TIGER updates between the big decennial version. Commented Jan 3, 2017 at 14:23

1 Answer 1


The Census Bureau does not update crosswalk files beyond the decennial remapping. Anthony Damico's suggestion of using HUD's crosswalk files, which are updated quarterly, is the best answer.

(Marking this as a community-wiki answer since I don't intend to take credit, just want there to be an "answer" to this question.)

  • how does one mark things as community wiki?

    @Albert when editing your own answer there's a checkbox on the lower right that says 'community wiki'. You can see that right now below the edit memo Your answer
