Time Use Data Access System
Dr. Sandy Hofferth
The Time Use Data Access System is a five-year, $3 million grant from the National Institute of Child Health and Human Development (NICHD) to integrate, document and disseminate individual-level data on how people allocate their time. This project facilitates research on parental time with children, how time use influences heath, household responses to changing economic conditions, and cross-national research on health and well-being in different cultural and policy settings. Current data come from the American Time Use Survey, a nationally representative survey of American households from 2003 to the present. Future data will include historical time use studies and international time use data sets.  The data are accessible through a web site:
