Pat Ruggles

Patricia Ruggles is a Senior Fellow with the Economics, Labor and Population Studies department. She has worked throughout her career to improve the quality of the economic and social statistics used for research and policy analysis. She has been involved in the development of methods for analyzing longitudinal data sets since the 1980s, when she was a researcher at the Urban Institute. She was an early user of the Survey of Income and Program Participation (SIPP), using it to create integrated longitudinal files for the analysis of income and poverty spells over time. She served on the National Academy of Sciences Panel to evaluate the SIPP in 1989 and 1990.

Patricia has held two NSF/ASA fellowships at the Bureau of the Census, both focused on improving data quality and usability.. The analyses of poverty-related issues that came out of her first NSF fellowship contributed to her book, Drawing the Line, which analyzed the impacts of alternative poverty measures. That book led to a major review of poverty measurement by the National Academy of Sciences, and  Census is now issuing a Supplemental Poverty Measure (SPM) that incorporates those recommendations. Patricia‚Äôs second NSF fellowship at Census focused on improving welfare program data in the SIPP, and led to her well-known work with Rebecca Blank on the dynamics of welfare spells. Patricia has also published many other studies based on the SIPP, the Panel Study of Income Dynamics (PSID) and other longitudinal data bases.

Patricia joined the staff of the Joint Economic Committee of the U.S. Congress in 1990, where she was concerned with data and measurement issues that affect policy analysis. In addition to a series of hearings on poverty measurement, she organized hearings on price measurement, unemployment, productivity, and other major economic indicators. She also worked extensively on issues relating to health insurance, health needs, and welfare. After a break to serve in the Clinton Administration, Patricia returned to the JEC as staff director in 2000.

In 1996 Patricia became the Deputy Assistant Secretary for Income Policy and the Chief Economist for the U.S. Department of Health and Human Services. In that role she was responsible for an annual budget of about $20 million to oversee research on issues relating to income and poverty.

More recently, Patricia has worked at the National Academy of Sciences on projects relating to social and economic indicators and on a re-evaluation of the SIPP. She has also consulted with the city of New York on the creation of a city-specific poverty measure and with the United Nations on tracking environmental data in the context of the System of National Accounts.
