Is there a way to merge AHTUS data with the USA (census samples) data? I see in the sample description for AHTUS 1930, for example, that there is a high match rate to census data, but am not sure what identifiers can or should be used to execute this match, for 1930 or the other available time use years. Thanks!
IPUMS Time Use does not provide linked data or the identifiers used for these links such as respondent names. I recommend referring to the work of Dr. Teresa Harms at the Centre for Time Use Research who linked these respondents to census records and reaching out to her with any questions. This IPUMS blog post includes a video of a presentation by Dr. Harms describing this work.
