Administrative records and survey data present multiple, sometimes contrary, representations of society. The comparison of multiple data sources often can improve our understanding and measurement of social characteristics. The integration and reuse of data provides us the capacity to produce new information in response to needs while minimizing respondent burden and cost to taxpayers. The integration of administrative and survey data has been integral to important Census Bureau programs for many years. This paper presents a theoretical perspective on this integration and reuse of data and includes a discussion of the benefits of these applications, such as enhancements to current survey questionnaire design and wording, address and survey frames, cost modeling and statistical toolkits for field operations, survey controls, and the rapid delivery of statistical information.
