Midlife in the United States: Core Sample Mortality Data, 1995-2025 (ICPSR 37237)
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 mortality information for all known MIDUS decedents (N=2,822) from the Core National and Milwaukee samples as of December 2025.
Monitoring the Future Longitudinal Panel Mortality Data and Weights, United States, 1976-2019 [Restricted Use] (ICPSR 39651)
Since 1976, MTF has enrolled ~2,450 individuals each year from its nationally representative annual sample of 12th graders into the MTF Longitudinal Panel study. A primary goal of MTF study is to examine potential consequences of substance use across the life course, including mortality. Therefore, the MTF Longitudinal Panel study now includes measures of mortality linked to the National Death Index (NDI).
The "MTF Longitudinal Panel Mortality Data and Weights, Cohorts 1976-2019 (Updated March 2026)" file includes MTF Longitudinal Panel members from the high school cohorts of 1976-2019 whose mortality status was confirmed through either (a) the MTF NDI match process or (b) the MTF panel tracking process (tracking through March 2026).
This updated file includes:
- The Panel Eligibility and Sampling Weight (PESW) variable to be used when mortality status is the outcome.
- Continued data management to update respondents and mortality status.
See the MTF Occasional Paper No.102 for details on the MTF mortality data and weights. Information about the MTF project can be accessed through the Monitoring the Future website. Annual reports are published by the research team, describing the data collection and trends over time.
Midlife in the United States: Refresher Sample Mortality Data, 2012-2023 (ICPSR 38024)
In 2011-2014, the MIDUS recruited a national probability sample of 3,577 adults, aged 25 to 74, designed to replenish the original MIDUS 1 (M1) baseline cohort and paralleling the five decadal age groups of the M1 baseline survey (ICPSR 2760).
The MIDUS Refresher (MR1) survey included the same comprehensive assessments as those assembled on the original MIDUS Core sample (obtained via interview and self-administered questionnaire), but with additional questions about the effect of the economic recession of 2008-09.
In 2012-2013, the National MIDUS Refresher sample was augmented with a sample of 508 Milwaukee African American adults, aged 25 to 64. This sample was designed to increase the number of racial minorities included in the MIDUS study. The MIDUS Milwaukee Refresher survey also included the same assessments as those in the Milwaukee Core sample (ICPSR 22840) and employed a personal interview. This dataset includes all known decedents from the National (ICPSR 36532) and Milwaukee (ICPSR 36722) Refresher samples, and is current for NDI records through December, 2023.
Tsogolo la Thanzi (TLT): Verbal Autopsy Data, Malawi, 2009-2019 [Healthy Futures] (ICPSR 39181)
Tsogolo la Thanzi (TLT) was a longitudinal study in Balaka, Malawi designed to examine how young people navigate reproduction in an AIDS epidemic. Tsogolo la Thanzi means "Healthy Futures" in Chichewa, Malawi's most widely spoken language. This particular study contains the Verbal Autopsy data providing information on 36 respondents who died over the study period (2009-2019). These 36 individuals were known to be deceased through recruitment efforts to re-interview the person during a subsequent wave of data collection. However, not all groups of respondents were re-interviewed in 2012, 2015, and 2019. Therefore, the total number of deaths from the original sample is potentially more than what is reported in this particular study. The 36 verbal autopsy cases in this study represent known deaths, and should not be interpreted as an inventory of all deaths that occurred.
Developing Methods for Assessing Outcomes of Law and Policy on Drug Trafficking Offenders, Organizations, and Criminal Justice Responses, United States, 2000-2018 (ICPSR 38441)
This project sought to gather and analyze data on the effects of marijuana legalization from primary and secondary data sources that are both local and national in scope, and at both the individual and aggregate level. Since 1996, 37 states have passed statutes legalizing marijuana for medical and/or recreational use, while it has remained illegal under federal law. Jurisdictional and temporal variation in law creates a complex environment and substantial challenges for police and prosecutors charged with enforcement, and little is known about the justice system processing, public safety, and public health outcomes of evolving laws and policies.
Secondary criminal justice and public health data were gathered from federal, state, and local sources. Each source has a sufficiently long time series to provide statistical power and to allow for sometimes gradual implementation. The design exploits geographic and temporal variation in the implementation of marijuana law, using a difference-in-differences design that compares outcomes in states which implemented the policies with states that did not, before and after implementation.

Shaping Long Term Care in America, [United States], 2009-2011 (ICPSR 37394)
The Vermont Study on Aid-in-Dying, 2016-2018 (ICPSR 37209)
Legislative support for physician aid-in-dying (PAD) in the US has risen steadily in recent years. In May 2013, Vermont became the fourth state to legalize PAD, through the "Patient Choice and Control at End of Life" Act (Act 39). The law authorized physicians to prescribe a lethal dose of medication to a mentally competent, terminally ill, adult patient for the purpose of ending the patient's life. With ongoing legislative activities in many other states, these laws are expected to spread nationally. This shifting legislative climate raises questions about how societies respond to changes in the sociocultural and biopolitical organization of death. While social scientists have examined the social and political forces that shape 'right to die' movements and counter-movements, sanctioning the right to die is only the first step in institutionalizing PAD as a new cultural and medical practice. What happens once these rights are legally authorized?
The purpose of this study was to learn about how people in Vermont have been affected by Act 39. This 2-year ethnographic study (July 2016-June 2018) addressed the following overarching research questions:
- How do ordinary people understand, access, experience, and contest the 'right to die' through PAD once it has been granted?
- How do healthcare providers and policy stakeholders accommodate or resist PAD as a new end-of-life practice?
- How does PAD affect the cultural landscape of care for the dying in the US?
Due to the recent enactment of Act 39, and Vermont's small size and the geographic proximity of key institutions, Vermont offered an ideal setting to explore these questions and document emergent responses to a new socio-legal phenomenon across multiple sites. By tracing the social life of Act 39 from the Vermont State House to the institutions, experts, and ordinary people responsible for managing death, this study yielded valuable information about the broad sociocultural consequences of legalizing PAD, including unintended consequences, that will be relevant to US policymakers, clinicians, patients, and families.
This collection includes semi-structured interviews with seriously ill Vermont patients, survivors of people who have used Act 39, healthcare providers and administrators, activists, and legislators, as well as participant observation in settings in which PAD is likely to be discussed. Participants were asked about their personal and professional backgrounds, attitudes on death and the legalization of PAD, understandings of the physician's role and responsibilities regarding end-of-life care, and interactions between healthcare providers, patients, and caregivers about PAD. The age, gender, and race of the participants are also provided.

Johns Hopkins University Prevention Research Center - Risks for Transitions in Drug Use Among Urban Adults, Baltimore City, 2008-2011 (ICPSR 36622)
The Johns Hopkins University Prevention Research center - Risks for Transitions, Baltimore city, 2008-2011 study (JHU PRC Risks for Transition in Drug Use among Urban Adults) represents data collected for a 25 years follow-up from the original JHU PRC study. At the start of the data collection, a cohort of 2,311 youth were randomly assigned to two classroom-based universal preventive interventions implemented in 43 classrooms of 19 public schools located in 5 socio-demographically distinct areas in Eastern Baltimore. This collection includes data from 1,434 respondents from the original cohort collected in 2008-2012. The mean age of the respondents was 30-32 years old.
Psychopathology (major depressive episode, phobia and anxiety disorders) was assessed using modules from the Composite International Diagnostic Interview-University of Michigan Version, CIDI- UM (WHO, 1997). An antisocial symptom scale adapted from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC) was administered which consisted of 30 questions that assessed behaviors experienced since turning 18 years of age. The alcohol, tobacco and drug modules of the interview were modeled after NESARC Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV. Types of information in these modules collected include age of onset, use in past year and prior past year, frequency and recency of use, and DSM-IV abuse and dependence criteria. Socioeconomic status indicators, variables on education, employment, marital status, parenthood, social supports, family history of mental health and drug problems, general health, treatment utilization, and life events are included in this dataset.
This dataset includes 3,140 variables.
Documentation of Resident to Resident Elder Mistreatment in Residential Care Facilities, New York City, 2009-2013 (ICPSR 35649)
These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.
The purpose of this study was to investigate violence and aggression committed by nursing home residents that is directed toward other residents, referred to here as resident-to-resident elder mistreatment (R-REM). Resident-to-resident mistreatment (R-REM) was defined as: negative and aggressive physical, sexual, or verbal interactions between long term care residents, that in a community setting would likely be construed as unwelcome and have high potential to cause physical or psychological distress in the recipient.
The goals of this project were to: enhance institutional recognition of R-REM; examine the convergence of R-REM reports across different methodologies; identify the most accurate mechanism for detecting and reporting R-REM; develop profiles of persons involved with R-REM by reporting source; investigate existing R-REM policies, and; develop institutional guidelines for reporting R-REM episodes. Also, the project team sought to answer the following research questions: (1) Will the reporting of R-REM differ by source? (2) Which reporting methods will show the highest level of convergence and accuracy in reporting? (3) What resident characteristics or profiles will predict R-REM across the differing reporting sources? (4) What are the existing guidelines and/or institutional policies for reporting R-REM? To achieve these goals, the researcher conducted this study over a two week period in five urban and five suburban New York City facilities. Resident-to-resident abuse information was derived from five sources: (1) resident interviews (2) staff informants (3) observational data (behavior sheets) (4) resident chart reviews (5) incident and accident reports.

The Deaths in Custody Reporting Program (DCRP) is an annual data collection conducted by the Bureau of Justice Statistics (BJS). The DCRP began in 2000 under the Death in Custody Reporting Act of 2000 (P.L. 106-297). It is the only national statistical collection that obtains detailed information about deaths in adult correctional facilities. The DCRP collects data on persons dying in state prisons, local jails and in the process of arrest. Each collection is a separate subcollection, but each is under the umbrella of the DCRP collection. The DCRP collects inmate death records from each of the nation's 50 state prison systems and approximately 2,800 local jail jurisdictions. In addition, this program collects records of all deaths occurring during the process of arrest. Data are collected directly from state and local law enforcement agencies.
Death records include information on decedent personal characteristics (age, race or Hispanic origin, and sex), decedent criminal background (legal status, offense type, and time served), and the death itself (date, time, location, and cause of death, as well as information on the autopsy and medical treatment provided for any illness or disease).
This data collection represents a single year of DCRP Jails data. The variable names and coding, while similar to other years, have not been standardized across years. The concatenated multi-year versions of the DCRP Jails population data have been edited to correct outliers and other data anomalies. Researchers are encouraged to use the concatenated multi-year data for final jail population data.

TAZAMA Health and Demographic Surveillance System, 1994-2012 (ICPSR 29541)
The TAZAMA Health and Demographic Surveillance System (HDSS) study site is located in the Kisesa and Bukandwe rural electoral wards in the Magu district of the Mwanza Region in Northern Tanzania. The two wards are comprised of six villages. There is one health center and five dispensaries (3 public and 2 private) in the study area. The two wards have eleven government primary schools (at least one in each village) and two secondary schools. Both Mwanza city and Magu town are accessible to residents; buses run along the main road and take about an hour and a half to get to Mwanza. Most of the residents are subsistence farmers; a lot of surplus agricultural produce is traded in Mwanza, which is Tanzania's second city. In the year 2012, the research study covered a population of about 30,000 people who live in the Kisesa and Bukandwe wards. The majority of the residents (about ninety five per cent) belong to the Sukuma ethnic group.
The DSS collects information on births and deaths and movements in and out of the households. It helps researchers to understand the population dynamics in the study area including fertility, mortality and migration patterns. It provides information on the structure of families that live together. The DSS study is also used to identify people who are eligible to participate in the serological surveys (the right age group, and continuously resident rather than just visiting). It provides the data for calculating the denominators for demographic rates.
The objectives of this study are as follows: (1) to improve understanding of the dynamics of the HIV epidemic; (2) to assess the demographic, social and economic impacts of the HIV/AIDS epidemic; (3) to evaluate the effects of national prevention, treatment and care interventions as implemented in Kisesa Ward; (4) to measure child and adult mortality and fertility in the general population and by HIV status; (5) to asses the leading causes of death through verbal autopsy; (6) to assess changes in the family structure due to HIV epidemic; and (7) to provide reliable data for district health planning.
