2019 Data Linkage Day Includes Westat Research

Using a record linkage macro to identify duplicates. Measuring re-identification risk. Importing scanner data. These are just a few of the topics Westat staff discussed at the Data Linkage Day hosted by the Committee on National Statistics (CNSTAT) earlier this month. The conference gave government employees the opportunity to share information about important data linkage initiatives available today.

Hundreds of participants attended the conference, representing 15+ federal agencies. They listened to presentations and discussed posters on data linkage, integration, de-duplication, and analyses.

Andrea Carlson, Elina Tselepidakis Page, Kevin Kuczynski, TusaRebecca Pannucci, Kristin Koegel, Thea Zimmerman, Carina Tornow, and Sigurd Hermansen. (Presentation). Importing Nutrients into Scanner Data and Estimating Prices for Foods in the National Health and Nutrition Examination Survey: The Purchase to Plate Crosswalk and Food Price Tool.

In addition, Elina Tselepidakis Page of the U.S. Department of Agriculture’s Economic Research Service described results of FoodAPS-2, a project that Westat supports, that identifies existing food databases through which people can, accurately and in real time, report food purchased. Zaria Tatalovich-Wenzel of the National Cancer Institute presented linkage initiatives of the Surveillance, Epidemiology, and End Results (SEER) Program, which Westat is providing scientific, technical, and logistical support.
