description: In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74 [ICPSR 2760]. The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. The study was innovative for its broad scientific scope, its diverse samples (which included siblings of the main sample respondents and a national sample of twin pairs), and its creative use of in-depth assessments in key areas (e.g. daily diary of stressful experiences [ICPSR 3725] and cognitive functioning [ICPSR 3596]) on a subset of participants. A detailed description of the study and findings generated by it are available at: http://www.midus.wisc.edu
With support from the National Institute on Aging, a follow-up of the original Midlife Development in the United States (MIDUS) sample was conducted in 2004 (MIDUS 2 [ICPSR 4652]). The daily stress and cognitive functioning projects were repeated and expanded at MIDUS 2; in addition the protocol was expanded to include biomarkers and neuroscience.
In 2013 a third wave (MIDUS 3) of survey data was collected on longitudinal participants. Data collection for this follow-up wave largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas such as economic recession experiences. Cognitive functioning data were also collected at the same time, while data collection for the daily diary, biomarker, and neuroscience projects commenced in 2017.
 MIDUS also maintains a
Colectica portal, which allows users to interact with variables across waves and create customized subsets. Registration is required.
description: The Aggregate Data dataset contains 2,613 variables and 3,294 cases. This dataset includes information about the following types of variables: recession experience, health, education, occupation, marital status, household roster, children, caregiving, living arrangements, race and ethnicity, life satisfaction, health insurance, personal beliefs, finances, community involvement, neighborhood, social networks, sexuality, religion and spirituality, discrimination, childhood family background, images of life change, and psychological turning points.
The Disposition Codes dataset contains 6 variables and 7,108 cases. This dataset contains final disposition codes for the M3 phone interview.
The Coded Text Data dataset contains 183 variables and 3,137 cases. This dataset contains coded text responses to open-ended questions and those which had "Other-specify" responses.
description: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
					disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
					statistical software formats as well as standard codebooks to accompany the data. In addition to
					these procedures, ICPSR performed the following processing steps for this data collection:
					Created online analysis version with question text.; Checked for undocumented or out-of-range codes..

description: Response Rates:
					77 percent of living longitudinal participants completed the M3 phone survey. Details of fielding and final disposition codes for Phone, SAQ, as well as Cognitive data collection projects can be found in the Field Report.
