I am looking for a detail metadata (detail than the code books) on how the variables were calculated. For instance there is a variable named “total household type (H8C001)”. I am not sure what this variable actually represents.
Detailed subject metadata can be found at this site. In particular, the ACS subject definitions (at the very bottom of the site I linked to) provide detailed descriptions about the variables included in the tables.
For example, the H8C001 (total households) are the sum of Family households (H8C002) and Nonfamily households (H8C007). If you read through the ACS subject definitions, you will find the definitions for “family households” and “nonfamily households”.
I hope this helps!
