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.

With support from the National Institute on Aging, an initial follow-up of the original Midlife Development in the United States (MIDUS) samples was conducted in 2004 (MIDUS 2). The daily stress and cognitive functioning projects were repeated 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 (e.g., economic recession experiences, optimism and coping, stressful life events, and caregiving). A third wave of cognitive functioning data were also collected. Demographic and background information includes gender, age, education, marital status, income and household composition.

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 data sets using the variable M2ID, including wave 1 (ICPSR 2760) and wave 2 (ICPSR 4652).

The P.I. Documentation found in this collection refers to the MIDUS Refresher data set. Please note that the data and corresponding documentation for this data set have not been deposited to ICPSR at this time.

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

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.

All respondents who completed the M2 phone interview were eligible to participate in the M3 survey.

The Aggregate Data set contains 2575 variables and 3294 cases. This data set includes information about the following types of variables: recession experience, health, education, occupation, marital status, household roster, children, caregiving, living arrangements, race and ethnicity and life satisfaction.

The Mortality Data set contains 9 variables and 1299 cases. This data set includes the updated decedent status of MIDUS and Milwaukee participants as of October 2015.

The Disposition Codes data set contains 6 variables and 7108 cases. This data set contains final disposition codes for all 7,108 individuals who participated in the M1 baseline survey.

77 percent of living longitudinal participants completed the M3 phone survey. Details of fielding and final disposition codes can be found in the Field Report.

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.

The data are not weighted. Since M3 was the third wave of a longitudinal survey, there was no sampling and so no sampling weights were created. Post-stratification weights for M3 (adjusted to population parameters) will be forthcoming.


  • 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.
