American Time Use Survey Activity Coding Lexicons
The ATUS Activity Coding Lexicon is a 3-tiered classification system with
17 first-tier categories. Each of the first-tier
categories has two additional levels of detail. Respondents' reported activities are assigned
6-digit activity codes based on this classification system. Activity codes
are periodically evaluated and updated prior to the start of each years
data collection. This page contains links to the ATUS Activity Coding
Lexicons.
