This provides a translation list between the columns in the geojson files (X01, X02, ... etc) and their human readable industry names as pulled fromthe LEHD Origin-Destination Employment dataset. The LEHD codes can also be mapped to 2 Digit NAICS codes, and that translation can be found on page 5 here. Note that our variables are simply the RAC variables in the above link, except we replace 'CNS' with 'X' to keep file sizes as small as possible.
