Integrating Data from Multiple Public Sources

Abstract

This article aims to inform evaluators about issues involved in using and integrating administrative databases from public agencies. With the growing focus on monitoring and oversight of public programs for health, mental health and substance abuse problems, existing data sets in public agencies became an important source of evaluation and planning information. The focus of this article is on the methods used to find, integrate and analyze multiple existing databases. Primary challenges that confront the evaluator in identifying and accessing data sources and in addressing the technical issues involved are discussed.
