Two questions, actually:
- Looking over the codes in the INDNAICS variable [https://usa.ipums.org/usa/volii/indcross03.shtml]
I’m confused as to why there seems to be a mix of 3, 4, and sometimes 5-digit NAICS codes.
Is this a partial list of all codes available via ACS? Or is the unerlying microdata really not consistent to a particular NAICS level (3-digit sector, 4-digit industry groups, 5 or 6-digit industries?)
- Are there other surveys with more granular NAICS data–not necessarily tied to indviduals but maybe by region?
