Abstract: This seminar will feature an interagency discussion by the United States Census Bureau and the National Center for Health Statistics (NCHS) on the application of record linkage, its challenges, and statistical considerations when using linked data.
The Census Bureau analyzes linked files for many of its research projects. The record linkage process, because of its probabilistic nature, has false match and false non-match error. When using linked files for statistical analysis, it necessary to adjust for record linkage error. This talk provides an overview of techniques and suggests methods to adjust statistical analysis for linkage error.
NCHS' record linkage program links the Center's population health surveys to administrative records from the Centers for Medicare and Medicaid Services (CMS) and the Social Security Administration (SSA). In addition, linkage with the National Death Index ascertains mortality status for survey participants. This talk will focus on analytic challenges and opportunities when using the NCHS-CMS-SSA linked data files.
Many research projects at the Census involve matching persons across surveys and federal data to enhance the understanding of participation in various Federal programs. Fundamental to this work is a method to ensure the same person is linked across multiple files. The Census Bureau's Person Identification Validation System (PVS) uses probabilistic matching to assign unique person and address identifiers to federal, commercial, and survey data to facilitate linking persons across these files. This talk will discuss the PVS and it's methods.
