Periodically gathers information on family and unpaid caregivers to participants in the National Health and Aging Trends Study (NHATS). NSOC I (2011) and II (2015) provide cross-sectional snapshots about caregiving to older adults. In 2017, NSOC III included both a cross-sectional sample and longitudinal follow-up with helpers identified in 2015. Starting in 2021, NSOC will be conducted annually and will support both cross-sectional and longitudinal analyses. For details on how to obtain NSOC files, see Sensitive and Restricted Files under Data Access.
