Overview of NEWWS

The Department of Health and Human Services (HHS) undertook a study of the effectiveness of welfare-to-work programs:  the National Evaluation of Welfare-to-Work Strategies (NEWWS) is a study of the effectiveness of eleven mandatory welfare-to-work programs in seven locales:  Atlanta, Georgia; Columbus, Ohio; Detroit and Grand Rapids, Michigan; Oklahoma City, Oklahoma; Portland, Oregon; and Riverside, California. Program impacts were evaluated by comparing outcomes for a randomly assigned experimental group subject to program requirements with outcomes for control groups. As part of NEWWS, the effects of two approaches to preparing welfare recipients for employment were compared in three sites (Atlanta, Grand Rapids, and Riverside). In one approach, the human capital development approach, individuals were directed to avail themselves of education services and, to a lesser extent, occupational training before they sought work, under the theory that they would then be able to get better jobs and keep them longer. In the other approach, the labor force attachment approach, individuals were encouraged to gain quick entry into the labor market, even at low wages, under the theory that their work habits and skills would improve on the job and they would thereby be able to advance themselves. Data from all eleven sites is available.

The evaluation used a random assignment design to get reliable results. Sample members were followed for five years from the time they entered the study. Comprehensive data on economic outcomes, including information on quarterly Unemployment Insurance-reported earnings and monthly Temporary Assistance for Needy Families (TANF) and Food Stamp payments was collected.  A broad range of data was collected through surveys including data on educational attainment, family composition, housing status, wage progression, employment, child care, depression, and total family income.  In addition, effects on the well-being of the children of the mothers in the study were evaluated.  Four types of child outcomes were measured: cognitive development and academic achievement; safety and health; problem behavior and emotional well-being; and social development. Assessments in each of these areas were compared across research groups two and five years after the mothers entered the survey sample.

In three of the sites (Atlanta, Grand Rapids, and Riverside) two distinct types of welfare reform strategies were compared: a labor force attachment program and a human capital development program. A broad range of data has been collected in these three sites through maternal surveys including data on educational attainment, family composition, housing status, wage progression, employment, child care, maternal depressive symptoms, total family income, children's school readiness, school achievement, and behavioral outcomes. Sample members were followed for five years from the time they entered the study. Two-year and five-year follow-up data are available. The following files are available:

• 2-year full impact sample,
• Two-year client survey,
• Two-year child outcomes study survey,
• Two-year literacy and math test scores,
• Five-year full impact sample,
• Five-year client survey, and
• Five-year child outcomes study and teacher surveys.

Each file contains linked survey and administrative data. In all eleven sites, administrative data are available that include comprehensive, longitudinal data on economic outcomes, including information on quarterly Unemployment Insurance reported earnings and monthly AFDC/TANF and Food Stamp payments.

Several reports will be very helpful in understanding the NEWWS data, research methods, and results.

• In particular, Chapter 2 of the report "Evaluating Two Welfare-to-Work Program Approaches: Two Year Findings on the Labor Force Attachment and Human Capital Development Programs in Three Sites" (prepared by Gayle Hamilton, Thomas Brock, Mary Farrell, Daniel Friedlander, and Kristen Harknett, MDRC, 1997, Washington, DC: U.S. Department of Health and Human Services, Administration for Children and Families and Office of the Assistant Secretary for Planning and Evaluation; and U.S. Department of Education) provides detailed information on the research design, samples, and data sources.
• In addition, Chapter 1 and Chapter 2 of "Impacts on Young Children and Their Families Two Years after Enrollment: Findings from the Child Outcomes Study" (prepared by Sharon M. McGroder, Martha J. Zaslow, Kristin A. Moore, and Suzanne M. LeMenestrel, 2000, Washington, DC: U.S. Department of Health and Human Services, Office of the Assistant Secretary for Planning and Evaluation and Administration for Children and Families; and U.S. Department of Education) also provide an overview of the project and information on research design, samples, and data sources for the Child Outcomes Study.

In addition to the reports mentioned above, see [N.B. the links below are to the executive summaries of the reports]:

• "Evaluating Alternative Welfare-to-Work Approaches:  Two-Year Impacts for Eleven Programs" (prepared by Stephen Freedman, Daniel Friedlander, Gayle Hamilton, JoAnn Rock, Marisa Mitchell, Jodi Nudelman, Amanda Schweder, and Laura Storto, MDRC, 2000, Washington, DC: U.S. Department of Health and Human Services, Administration for Children and Families and Office of the Assistant Secretary for Planning and Evaluation; and U.S. Department of Education).

Information About the Restricted Access and Public Use Data

ASPE and ACF are making data from NEWWS available to researchers. Data for the two-year impact reports, as well as the five-year final impact report, are available. Data are available in two formats:  restricted access files and public use files. Both of these are available at the National Center for Health Statistics (NCHS)’ Research Data Center (RDC).  ASPE has established an interagency agreement with NCHS to make the restricted access data files available at the NCHS’ Research Data Center so researchers can access the data while preventing disclosure of confidential information. The public use data, in which certain variables have been top-coded, collapsed, and otherwise masked, are also available at the RDC. The files are organized around the reports from NEWWS:  two-year impact reports, the adult basic education report, and the final report.

Differences Between the Public Use Files and Restricted Access Files

Data that could be used to identify individual sample members were deleted or grouped into broader categories when preparing the Public Use Files. These changes (which are summarized below) primarily affect sample members' background characteristics data and outcomes measured from administrative records, although some survey responses were also changed. The original values of these data items are stored in the Restricted Access Files at the RDC. Entries in the codebooks for the Public Use Files indicate when measures have been deleted or modified.

Background Characteristics: The Public Use Files include the year but not the specific date in which a sample member was randomly assigned; and the sample member's "site" (a county or a group of counties) but not the specific location of her welfare-to-work office. Other measures grouped into larger categories, include: sample member's educational attainment, and her scores on literacy and math tests administered at random assignment.

Administrative Records: Welfare and food stamp payment data originally collected by month are summed into quarterly totals. Measures of total earnings, welfare payments, and food stamp payments have been rounded to the nearest $100. Relative dates of earnings and public assistance payments are available (Quarter 1 = quarter of random assignment), but not actual dates. [Note: Actual dates are not stored on the Restricted Access Files either, but can be inferred from the relative date and the sample member's date of random assignment.]

Survey Responses: Actual dates of survey outcomes (and the survey interview date) have been deleted, although relative dates are available (Month 1 = month of random assignment). Dollar amounts of reported monthly income have been rounded to the nearest $50.

Child Outcomes Study: The age of the "focal child" for the Child Outcomes Study has been deleted. (All focal children were between 3 and 5 years old at random assignment.)

Below is information about the restricted access data sets. (Note that some of the files below are plain text or Microsoft Word files, not HTML files and some are quite large.)

How to Access the Data Files

ASPE has entered into an interagency agreement with the National Center for Health Statistics (NCHS) to facilitate placement of NEWWS files at the NCHS Research Data Center (RDC). To gain access to the restricted access data, a researcher will have to apply for the data by submitting a structured research proposal, sign an agreement not to disclose individual identities, and either come to the Research Data Center in Hyattsville, Maryland, or use a remote access (electronic) system (i.e., send SAS code through email). Applications for use of data will be reviewed and research use of the data will be monitored to prevent breaches in confidentiality and inappropriate disclosure of data. For example, the RDC does not allow researchers to print out individual observations or cells with fewer than five observations.

To gain access to the public use data, please contact Christopher Rogers at Christopher.Rogers@cdc.hhs.gov. There is no charge for the public use files, but the user will be required to sign an agreement not to disclose individual identities.

To support the ongoing maintenance of the restricted access files at the Research Data Center, NCHS charges researcher access fees. Currently, the RDC charges $1,000 per week for on-site access or $500 – $1,000 per month for remote access, depending on the size of the files. To alleviate the burden on researchers and encourage access to the NEWWS data files, ASPE plans to provide some subsidy of researcher fees, up to a set amount per project and a set amount of projects.
