Abstract: This session will demonstrate the use of PDQ-Explore and PDQ-Expert to access and analyze large microdata files. These include, among others, the Public Use Microdata Samples (PUMS) from the U.S. Census Bureau and the Integrated Public Use Microdata Series (IPUMS) from the IPUMS project at the University of Minnesota Population Center. The U.S. census microdata encompassed in the IPUMS files can be accessed as a single data set spanning 1850-1990 with the 2000 files to be added when available. PDQ-Expert provides a natural language, case-based reasoning interface to PDQ-Explore. It is designed to allow persons unfamiliar with microdata and basic analytic procedures to extract meaningful information from large and complex data sets. PDQ-Explore and PDQ-Expert are commercial products developed by Public Data Queries, Inc., with small business research support from the National Institute of Child Health and Human Development (NICHD) and the National Institute on Aging (NIA) of the National Institutes of Health (NIH).
