The site seeks to provide information about all Census 2000 data and documentation files, training activities, links to relevant sites for Census users, and guidelines to aid researchers and information professionals in the use of these files.

Child Care and Early Education Research Connections

RC promotes high quality research in child care and early education and the use of that research in policy making. Our vision is that children are well cared for and have rich learning experiences, and their families are supported and able to work. Through this Web site, we offer research and data resources for researchers, policy makers, practitioners, and others.

Collaborative Psychiatric Epidemiology Surveys (CPES)

The National Institute of Mental Health Collaborative Psychiatric Epidemiology Surveys (CPES) provides data on the distributions, correlates, and risk factors of mental disorders among the general population, with special emphasis on minority groups. This project joins together three nationally representative surveys: the National Comorbidity Survey Replication (NCS-R), the National Survey of American Life (NSAL), and the National Latino and Asian American Study (NLAAS). CPES permits the investigation of cultural and ethnic influences on mental health.

CrimeStat

CrimeStat is a spatial statistics program for the analysis of crime incident locations, developed by Ned Levine & Associates under the direction of Ned Levine, PhD, that was funded by grants from the National Institute of Justice. The program is Windows-based and interfaces with most desktop GIS programs. The purpose is to provide supplemental statistical tools to aid law enforcement agencies and criminal justice researchers in their crime mapping efforts. CrimeStat is being used by many police departments around the country as well as by criminal justice and other researchers. The new version is 3.0 (CrimeStat III).

Data Documentation Initiative (DDI)

The Data Documentation Initiative (DDI) is an emerging XML standard for social science metadata that is being developed by an international group called the DDI Alliance. Version 3.0 of the DDI documents the life cycle of research data from the start of a research project through data dissemination and analysis.

Data Preservation Alliance for the Social Sciences (Data-PASS)

Data-PASS is funded by an award from the Library of Congress to acquire and preserve data from opinion polls, voting records, large-scale surveys, and other social science studies. The three-year project is a broad-based partnership between the Inter-university Consortium for Political and Social Research at the University of Michigan, the Roper Center for Public Opinion Research at the University of Connecticut, the Howard W. Odum Institute at the University of North Carolina-Chapel Hill, the Henry A. Murray Research Archive, a Member of the Institute for Quantitative Social Science at Harvard University, the National Archives and Records Administration, and the Harvard-MIT Data Center, also a member of the Institute for Quantitative Social Science at Harvard University.

Data Sharing for Demographic Research (DSDR)

DSDR is a project of ICPSR in collaboration with the Carolina Population Center (CPC) at the University of North Carolina at Chapel Hill, the Minnesota Population Center (MPC) at the University of Minnesota, and the Population Studies Center (PSC) at the University of Michigan. The project is supported by the Demographic and Behavioral Sciences Branch of the National Institute of Child Health and Human Development. DSDR supports research investigators -- both those who collect data and those who wish to use data -- in dealing with complex data and data requiring special security.

Digital Preservation at ICPSR

The primary objective of the digital preservation function is to ensure long-term access to the more than 500,000 files in the ICPSR collections. ICPSR is a data archive with a 45-year track record for preserving and making data available. Within that context, digital preservation is carried out as a distributed function that is integrated into ICPSR operations.

Digital Preservation Management Tutorial

In August 2007, ICPSR became the host for the award-wining Digital Preservation Management tutorial developed at Cornell University Library by a team led by Anne R. Kenney and Nancy Y. McGovern, the Digital Preservation officer at ICPSR. ICPSR is also a designated provider of the Digital Preservation Management workshop curriculum that builds on the tutorial content. We will continue to provide versions of this workshop and to seek funding to expand the curriculum as an ongoing contribution to the digital preservation community.

Grammars of Death: Nineteenth Century Literal Causes of Death from the Age of Miasmas to Germ Theory

This project seeks a better understanding of the later nineteenth-century mortality plateau and eventual mortality transition in America, through a formal semantic analysis of literal causes of death in the Connecticut River Valley mill towns of Holyoke and Northampton, Massachusetts from 1850 to 1912. We address the problem of precision of historical cause-of-death data through an integrated archival social history of death reporting, and analyses of changing historical cause-of-death nomenclature, social biases in the reporting of deaths and probabilistic cause-of-death classification. These analyses allow the estimation of robust cause-specific mortality trends for major causes of death and selected causes of importance, which will shed light on past and future epidemiological transitions. This is a collaborative project with the University of Massachusetts funded by the National Institute for Child Health and Human Development.

Health and Medical Care Archive (HMCA)

HMCA is sponsored by the Robert Wood Johnson Foundation, the largest health care philanthropy organization in the United States. HMCA is the official data archive of the Foundation, and is devoted to preserving and making available research data that have significant secondary-analytic value for expanding knowledge on, and ultimately contributing to, improvement of the health of people in the United States.

Homicide Research Working Group (HRWG)

HRWG, an interdisciplinary and international association of researchers and policy makers, was formed in 1991 to foster communication, coordination, and networking among people involved in the study of homicide. ICPSR maintains the HRWG Web site, which provides information on HRWG news, meetings, membership, and publications.

Human Subject Protection and Disclosure Risk Analysis

This program aims to answer the call for knowledge and innovation that has arisen out of recent events and inquiries about studies involving human subjects. Analyses underway now at influential public institutions such as the National Academy of Sciences and the Institute of Medicine are likely to call for new research on the risks of human research. In the area of social science research, we expect those calls to emphasize the reduction of disclosure risk and the creation of new responsibilities for data dissemination.

ICPSR General Archive

As a service to ICPSR member institutions, the General Archive acquires and processes data collections in a wide range of social science disciplines including political science, sociology, economics, psychology, and education. The Archive maintains and updates a number of longstanding serial data collections and also acquires datasets for its Publication-Related Archive, which allows researchers to replicate published articles, books, or dissertations. The goal of the archive is to support the needs of the research community through the enhancement of its diverse holdings after consultation with the ICPSR Council, ICPSR's Official Representatives, and interested scholars.

International Archive of Education Data (IAED)

IAED is a project formerly sponsored by the National Center for Education Statistics. The education data stored in this archive are intended to support a wide variety of comparative and longitudinal research through the preservation and sharing of data resources. The archive seeks to serve the needs of academics, policymakers, and researchers in the field of education.

International Data Resource Center (IDRC)

As the international community is drawn closer together through the phenomenon of globalization, access to international data has become critical for scholars and researchers around the world. Finding reliable data sources that reflect international dimensions can be difficult. In an effort to meet the growing demands for international data, the Inter-university Consortium for Political and Social Research (ICPSR) has created the International Data Resource Center (IDRC). The IDRC acts as a clearinghouse for international data housed at ICPSR.

Mexican American Trajectories: Family, Geography, and Intermarriage Across a Century

This Web site examines family and household relationships of Mexican origin Americans between 1880 and 1990. The research contrasts Mexican Americans to a variety of other immigrant origin groups (the Irish, Italians, Poles, Chinese, and Puerto Ricans) and to blacks and native whites. It assesses the effects of ethnicity on family structure, and especially on the household circumstances of children.

Minority Data Resource Center (MDRC)

MDRC is a membership-funded archive whose purpose is to provide data resources for the comparative analysis of issues affecting racial and ethnic minority populations in the United States. We offer streamlined access to existing ICPSR data and to newly acquired studies that are relevant to the study of immigration, place of origin, ancestry, ethnicity, and race in the United States. Access to MDRC data is available to anyone at an ICPSR member university or institution.

National Archive of Computerized Data on Aging (NACDA)

NACDA is funded by the National Institute on Aging. NACDA's mission is to advance research on aging by helping researchers to profit from the under-exploited potential of a broad range of datasets. NACDA acquires and preserves data relevant to gerontological research, processing as needed to promote effective research use, disseminates them to researchers, and facilitates their use.

National Archive of Criminal Justice Data (NACJD)

NACJD was established in 1978 under the auspices of ICPSR and the Bureau of Justice Statistics, U.S. Department of Justice, and currently also receives funding from the National Institute of Justice, U.S. Department of Justice. At present, NACJD holds over 700 data collections relating to criminal justice. NACJD facilitates and encourages criminal justice research through the preservation and sharing of data resources, and through the provision of training in quantitative analysis of crime and justice data.

Online Learning Center (OLC)

The OLC is the result of discussions with teaching faculty about using data in their classrooms and the challenges such undertakings can entail. Instructors directed ICPSR to develop tools that would: 1) quickly locate relevant data that are easy to work with and that nicely demonstrate the concept(s), and 2) enable the instructor to customize the materials to their own teaching approach and syllabus.

Population and Environment in the U.S. Great Plains

This project is a study of the reciprocal relationship between population and environment in the American Great Plains focusing on the relationship between the agricultural land-use and demographic behavior. The researchers have collected county-level data on agriculture, population, and the biophysical environment from between 1870 and the present (for roughly 450 counties), and collaborated on local small-scale studies. Funded by the National Institute for Child Health and Human Development, the project's county dataset is now based at the University of Michigan, where the principal investigator serves as ICPSR director, and a web-based extraction system will be made publicly available.

PreK-3rd Data Resource Center: The First Six Years of Schooling and Beyond

The PreK-3rd Data Resource Center is an online resource center designed to expand the knowledge base and provide tools for the access and handling of Prekindergarten through Third Grade longitudinal data. The goal of this project is to inform the Foundation for Child Development's PreK-3rd initiative and build the research field by facilitating the analysis of rich, complex, longitudinal datasets that contain a wide range of variables on the child, family, school, and neighborhood. The Web site disseminates datasets and user guides developed to provide researchers with detailed guidance in creating their own extract datasets.

Project on Human Development in Chicago Neighborhoods (PHDCN)

PHDCN is a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. It was designed to advance the understanding of the developmental pathways of both positive and negative human social behaviors. In particular, the project examined the causes and pathways of juvenile delinquency, adult crime, substance abuse, and violence. At the same time, the project also provided a detailed look at the environments in which these social behaviors take place by collecting substantial amounts of data about urban Chicago, including its people, institutions, and resources.

Substance Abuse & Mental Health Data Archive (SAMHDA)

SAMHDA is an initiative of the Office of Applied Studies at the Substance Abuse and Mental Health Services Administration of the United States Department of Health and Human Services. The goal of the archive is to provide ready access to substance abuse and mental health research data and to promote the sharing of these data among researchers, academics, policymakers, service providers, and others.

Terrorism & Preparedness Data Resource Center (TPDRC)

TPDRC archives and distributes data collected by government agencies, non-governmental organizations, and researchers about the nature of intra- (domestic) and international terrorism incidents, organizations, perpetrators, and victims; governmental and nongovernmental responses to terror and citizen's attitudes towards terrorism, terror incidents, and the response to terror.
