Steven Pedlow is a Senior Survey Statistician in the Statistics and Methodology Department. He is NORC's lead statistician on the Survey of Consumer Finance and other surveys. Pedlow is NORC's expert in imputation, and also has expertise in sample design, sample weighting and other estimation issues, especially for area probability surveys.

Pedlow has designed or consulted on every implementation of hot-deck and multiple imputation at NORC in the past ten years (which includes the Survey of Doctorate Recipients, the Residential Energy Consumption Survey, and multiple surveys under the National Immunization Survey umbrella). His weighting expertise includes combining a cell phone sample with a landline phone sample (for the Minnesota Health Access Survey), combining independent samples with unified probabilities rather than using composite weights (for the National Longitudinal Survey of Youth), constructing complicated panel weights (for the General Social Survey and Making Connection studies), and reducing the impact of outlier weights (for the Racial and Ethnic Approaches to Community Health 2010 study). Pedlow has also been a leading sample designer for the 1997 National Longitudinal Survey of Youth, OSHA's current procedure for the evaluation of Accuracy and Completeness of an Establishment's OSHA-Mandated Employer Records, the 2010 Census Integrated Communication Program Evaluation, and the 2010 NORC National Frame for Area Probability Surveys.

Consulting work he started in graduate school has resulted in co-authorship for articles in Pediatrics, Journal of Pediatric Endocrinology and Metabolism, Journal of Abnormal Child Psychology, Anesthesia and Analgesia, and Journal of Vocational Education Research. Pedlow has also presented papers to the American Statistical Association and American Association of Public Opinion Research on the weighting topics listed above as well as such topics as post-Katrina control totals in New Orleans, linear programming to balance automatic case assignments for field interviewers, variance estimation for ordered categories, the impact of clustering on effective sample sizes, interviewer intervention for data quality, Benford's Law to detect falsified cases, sampling undercoverage, and multiple imputation.   

Pedlow is currently the newsletter co-editor for the Survey Research Methods Section of the American Statistical Association.

Representative Projects

The Study of the Food Distribution Program on Indian Reservations. The Food Distribution Program on Indian Reservations (FDPIR) provides commodity foods, fruits and vegetables to low-income households, including the elderly, living on Indian reservations and to American Indians residing in designated areas in Oklahoma. The study will provide current information on the participant characteristics, reasons for participation, local program administration, and access barriers. NORC will review a national probability sample of FDPIR case records and conduct interviews with 832 FDPIR households across 25 FDPIR programs, analyze these data, and create a public use data file. NORC will also engage in tribal consultations with USDA and conduct outreach with tribes.    More

2010 National Sample Frame. U.S. households are the primary unit for sample selection for many studies, but sample frames for households can be difficult and expensive to create. In order to provide a sample frame for use by many surveys, NORC has constructed the 2010 National Sample Frame, based on the 2010 Census information. This sample is representative of over 99% of U.S. households and provides a listing of almost 3 million households, including over 80,000 rural households. More

Survey of Consumer Finances (SCF).

Sponsored by the Federal Reserve Board, this triennial survey is the only fully representative source of information on the broad financial circumstances of U.S. households. No other survey collects data on the household finances of a probability sample of Americans.  Data from the SCF are used to inform monetary policy, tax policy, consumer protection, and a variety of other policy issues. The data also serve as a basis for longer-term research on the economic state of the American family. More

Survey of Economically Successful Americans. Economically successful Americans have views about national problems that can be of great value to scholars and policy makers.  But little is known about the views of the most successful Americans which leads to these views being ignored and sometimes distorted by the media.  The Survey of Economically Successful Americans and the Common Good (SESA) gives this select group a rare opportunity to make their voice heard by academics and policy makers engaged in matters of national importance. More

2010 Census Integrated Communications Program Evaluation. NORC was selected to conduct a rigorous and independent evaluation of the communications campaign for the 2010 Census to assess the campaign's success and help preparations for the 2020 Census. More
