On the basis of its review of the Census Bureau's plans and research regarding the use of sampling for nonresponse follow-up, the panel recommends direct sampling, appropriate sampling rates, an adequate budget, and the use of housing units as the sampling unit during nonresponse follow-up.

For integrated coverage measurement, the Bureau has recently decided to use dual-system estimation. The panel agrees with the decision and recommends combining the best aspects of alternative procedures, carrying out a total error analysis, and calculating the effects on state estimates.

Geographic Work. For the Census Bureau's geographic work, the panel finds that the Bureau's plans and progress to develop the most accurate Master Address File and TIGER map data base ever used in a decennial census are outstanding, both in terms of the goals and the proposed methodologies. The panel offers recommendations regarding the development of a cost-benefit model for the updating process, the establishment of explicit criteria for targeting updating checks, the development of a communication plan with local partners, and quality control checking.

Survey Methods. The panel finds that the Census Bureau is proceeding well in improvements in survey methods for the 2000 census, including respondent-friendly questionnaires, the availability of forms, targeted Spanish-language questionnaires, a formal promotional campaign, service-based enumeration, and, especially, improved public relations. The panel offers recommendations regarding criteria for distribution of Spanish-language forms, evaluation of the formal promotional campaign, and continuing research into the best ways to enumerate people with no usual residence.

Administrative Records. Looking at the Census Bureau's plans and research to date on the use of administrative records in the census process, the panel agrees with the Bureau's recent decision to limit the use of administrative records in 2000 and offers recommendations regarding further evaluation and research.
