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.

  1. The variable M2ID is the linking variable for the four datasets in this collection. The data in this collection can also be linked to all MIDUS datasets using the variable M2ID, including wave 1 [ICPSR 2760] and wave 2 [ICPSR 4652].

  2. Additional information about the Midlife Development in the United States study can be found at the MIDUS Web site.

  3. The title of this study was changed from National Survey of Midlife Development in the United States (MIDUS 3), 2013-2014, to Midlife in the United States (MIDUS 3), 2013-2014, on May 9, 2017.


Only living respondents who completed the M2 phone interview were eligible for participation in the M3 survey.


The noninstitutionalized, English-speaking population of the United States.

individual, household

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.

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.

For information regarding scales, please refer to the Psychosocial Constructs and Composite Variables.




This collection has been updated to include new data supplied by the P.I. The resupplied data includes new cases for the Self-Administered Questionnaire (SAQ) as part of the MIDUS M3 re-fielding effort undertaken to increase participant completion during 2015 fielding. The re-fielding cases can be identified and/or filtered with C1STATUS or the new M3RE_FILTER variables. Ten post-stratification weight variables (C1PWGHT1 through C1PWGHT10), and a new occupation variable based on Standard Occupation Classification system, have been added to the Aggregate dataset. Documentation has been updated accordingly. For more detailed information, please refer to the P.I.'s README file.

The Mortality dataset has been removed from this collection and is a separate study, Midlife in the United States (MIDUS3): Mortality Data, 2016 (ICPSR 37237).

The datasets have been renumbered:

  • Dataset 1: Aggregate Data
  • Dataset 2: Disposition Codes
  • Dataset 3: Coded Text Data

2017-11-21 This collection is being updated, per request from the PI, to reflect a title change; the corresponding downloadable files are only being updated to reflect the title change, where applicable.

2017-03-09 The coded text data set has been added. Additionally, the MIDUS 3 Readme documentation has been updated.

2016-03-10 The MIDUS 3 Readme documentation has been updated.

2016-03-07 The documents that were previously combined to create the User Guide have been filtered into the Pyschsocial Constructs and Composite Variables and the Naming and Coding Conventions documents. The documents combined to create the questionnaire documentation have been separated into the MIDUS 3 Telephone Interview and the MIDUS 3 Self-Administered Questionnaire (SAQ).

2016-02-29 The fully-processed collection is being released.

2015-12-18 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.

A set of post-stratification weight variables is available in the Aggregate Data dataset. Details are available in separate weighting documentation.



  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.
