DSDR Announces the release of The Nang Rong (Thailand) Projects Data For Restricted Use
DSDR is pleased to announce the availability of restricted data from The Nang Rong (Thailand) Projects: ICPSR Study No. 4402.
The Nang Rong Projects are designed to monitor and promote understanding of the sweeping demographic, social, and environmental changes taking place in Nang Rong, Thailand, over the last 20 years. Scholars from across the US and Thailand contribute to research on life course choices, fertility and contraceptive behavior, migration processes, and land use/land cover change. An interest in social networks in relation to these demographic and social processes informs much of this work.
The largest data collection of its kind, the Nang Rong database offers opportunities to explore critical questions about population and environment. Longitudinal data extending 20 years from more than 50,000 individuals as well as administrative records, and many other sources, are linked by geographic referents and individual, household, and community identifiers to provide a wide-ranging, flexible, and explicit database that is multi-thematic and multi-temporal. The data includes 20 years of longitudinal data on individuals, thorough follow-up of migrants and migration processes, documentation of complete social networks, and extensive household characteristics and village features. The restricted version of this data includes even greater detail, and provides an enhanced ability to link information across datasets.
The Nang Rong data includes 29 public datasets and 35 restricted-use datasets, all with the full ICPSR product suite with the data available in SPSSx, SAS, and STATA and includes codebooks that contain detailed information on variable construction as well as survey question text. A more detailed description of The Nang Rong Projects can be found on the project Web site.

L.A.FANS Wave 1 Public Data Available
DSDR now has The Los Angeles Family and Neighborhood Survey (L.A.FANS) Wave 1 public data available. The L.A.FANS is a longitudinal study of families in Los Angeles County and of the neighborhoods in which they live. The L.A.FANS was designed to answer key research and policy questions in three areas: the effects of neighborhoods and families on children's development; the effects of welfare reform at the neighborhood level; and the process of residential mobility and neighborhood change. L.A.FANS also provides a new data set for studying other important issues including: adult health and health disparities, immigrant well-being, social ties and neighborhood interaction, marriage patterns, ethnic identity, family survival strategies, and family dynamics.
The Los Angeles Family and Neighborhood Survey was funded by grant R01HD35944 from the National Institute of Child Health and Human Development. Additional funding was provided by the Office of the Assistant Secretary for Planning and Evaluation (OASPE) of the U.S. Department of Health and Human Services, Los Angeles County, the Office of Behavioral and Social Science Research (OBSSR) at the National Institutes of Health, and the Russell Sage Foundation.

National Couples Study
DSDR is happy to announce the release of the National Couples Study (NCS). Data from the NCS were collected as part of two NIH-funded studies examining couples' contraceptive decision making (but not consistency of use). This survey obtained separate, parallel reports from both partners, providing unique and detailed data on the power relations, birth desires, and method-related expectancies, values, perceptions, preferences, and behaviors of men and women making contraceptive and disease prevention choices within the context of an intimate heterosexual relationship.
Completed interviews were obtained from both partners of 413 married couples, 261 cohabiting couples and 335 dating non-cohabiting heterosexual couples (2,018 individuals), where the female is age 20 to 35 years, the male is age 18 or older, and neither partner is sterile. The survey collected data from an area probability sample of household residents in four cities and their adjacent county subdivisions: Baltimore, MD; Durham, NC; St. Louis, MO; and Seattle, WA.
The NCS (Study #24384) includes Wave 1 for all couples and Wave 2 data for the female partner in married and cohabiting couples. The data are available in SAS Transport (CPORT/CIMPORT), SPSS System, Stata DTA format as well as ASCII flat and Tab-delimited formats with SAS, SPSS, and Stata Setup Files; and includes codebooks that contain survey question text. The data are also available for online analysis.

Add Health Public Data Available
DSDR now has The National Longitudinal of Adolescent Health (Add Health) public data available. The National Longitudinal Study of Adolescent Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-95 school year. The Add Health cohort has been followed into young adulthood with three in-home interviews, the most recent in 2001-2002, when the sample was aged 18-26. Add Health combines longitudinal survey data on respondents' social, economic, psychological and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviors in adolescence are linked to health and achievement outcomes in young adulthood.
The Add Health data are available for download under ICPSR Study Number 21600. The data are available in SAS Transport (CPORT/CIMPORT), SPSS System, Stata DTA format as well as ASCII flat and Tab-delimited formats with SAS, SPSS, and Stata Setup Files.
The Add Health data can be accessed either thru the ICPSR main page or the DSDR Add Health page. The DSDR Add Health page also provides a searchable index of Add Health publications.

Welfare, Children, and Families: A Three-City Study - Wave 1, 2, & 3 Public and Restricted data Now Available
DSDR is excited to announce the release of the public and restricted Wave 2 & Wave 3 data from the Three-City Study. DSDR previously had the public and restricted versions of the Three-City Wave 3 data.
The Three-City Study project is an intensive study in Boston, Chicago, and San Antonio to assess the well-being of low-income children and families in the post-welfare reform era. The project investigates the strategies families have used to respond to reform, in terms of employment, schooling or other forms of training, residential mobility, and fertility. Central to this project is a focus on how these strategies affect children's lives, with an emphasis on their health and development as well as their need for, and use of, social services.
The study comprises three interrelated components: longitudinal surveys, embedded developmental studies, and contextual, comparative ethnographic studies. DSDR has available data for all three waves on including child data, continuing and new caregiver data, and separated caregiver data as well as the embedded development survey data.
Additional user support and materials are available at the DSDR Three-City Study Web site:

Decennial Census Restricted Data Documentation
The Inter-university Consortium for Political and Social Research (ICPSR) and the Michigan Census Research Data Center are pleased to announce the availability of new documentation for the restricted versions of the 1990 and 2000 Decennial Censuses.
Working in conjunction with the Center for Economic Studies at the U.S. Census Bureau, ICPSR's Data Sharing for Demographic Research (DSDR) project has created documentation for these restricted data. These datasets are based on the Decennial Long Form Samples and include variables such as age, ancestry, sex, educational attainment, income, household characteristics, migration, commute time to work, occupation, and place of birth. This recently available documentation provides file summaries and variable information and facilitates sorting of the data.
For more information and to access the documentation, please visit the ICPSR Web site.
Access to the data is available only within the Census Research Data Centers and requires approval by the U.S. Census Bureau. Procedures for accessing these data are available at the U.S. Census Burueau Center for Economic Studies or Michigan Census Research Data Center (MCRDC). Funding for this project was provided by the Eunice Kennedy Shriver National Institute of Child Health and Human Development through DSDR.

QualAnon
DSDR announces the availability of a new Web based tool to assist in the anonymization of qualitative data. In collaboration with Susan Watkins at the University of Pennsylvania and ICPSR CNS programmer Peggy Overcashier, we have developed a Web based program that streamlines the process of removing or changing identifiers in qualitative data.
The program, QualAnon, takes a user-generated name key to replace identified names with pseudonyms. It has several options, including the option to have an annotated document created that identifies where specific changes have been made in the document. The program also creates a summary report that specifies the number of times a specific name has been replaced. In addition, QualAnon has a "batch" option that allows the users to anonymize several documents at once by uploading multiple documents as a Zip file using one corresponding name key.
QualAnon is a tool to assist in the removal of identifiers in qualitative research. It is not intended to replace the researcher's role in reducing disclosure risk and minimizing breach of respondent confidentiality.
Susan Watkins acknowledges support provided by the Population Studies Ctr., University of Pennsylvania, from the NIH/National Institute on Aging, Grant no. P30 AG12836; NIH/National Institute of Child Health and Development Population Research Infrastructure Program R24 HD-044964; and the Boettner Center for Pensions and Retirement Security at the University of Pennsylvania.
