PUMA Adjacency file

Hi, I was wondering if there are any files with PUMA adjacency information? In particular, I am looking for a file that lists, for each PUMA, the other PUMAs that border it. Similar to the Census Bureau county adjacency file. Thanks!

There is not an existing PUMA adjacency file that I know of. Here are a couple ways you can make your own:

  1. Polygon Neighbors tool in ArcGIS (as outlined on this ACS Data Users Forum thread)
  2. Poly2nb Function in R (as outlined on this StackOverflow thread)
