MIDUS Core Mortality

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 2005, a baseline sample of 592 African Americans from Milwaukee was added to MIDUS to examine health issues in minority populations.

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 and a second wave of the Milwaukee sample were also collected. Data collection for the daily diary, biomarkers, and neuroscience is ongoing. This dataset includes all known MIDUS decedents (N=2,124) from the Core National and Milwaukee samples as of December 2020.

  1. The variable M2ID is the linking variable in this collection. The data in this collection can be linked to all core MIDUS data sets using the variable M2ID, including Wave 1 (ICPSR 2760), Wave 2 (ICPSR 4652), and Wave 3 (ICPSR 36346).
  2. Additional information about the Midlife Development in the United States study can be found at the MIDUS Web site.

The primary purpose of this study was to obtain information about the underlying cause of death for Midlife in the United States (MIDUS) and Milwaukee decedents.

2124 prior participants in the MIDUS series with a confirmed decedent status.


All decedent participants of the MIDUS series.


The data set contains 10 variables and 2,124 cases. The variables include decedent status, source of decedent information, month and year of death, and International Classification of Diseases (ICD) codes.

The demographic variable, gender, is also included.

2019-03-21 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:

  • Checked for undocumented or out-of-range codes.


  • 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.
