Computer and Internet Use Supplement and Proxy

A reviewer for our paper using the data for the Computer and Internet Use Supplement asked about:
1a. What is the percent of proxies in the CPS Computer and Internet Use Supplement survey households? (also broken down by age group).

  1. What is the breakdown in proxy types? e.g., parent, spouse, sibling, grandparent, other relative, room renter, etc.

Where can I get the answers to these questions?
