It was charged with reviewing results of the 1995 and 1996 census tests, particularly with respect to sample design for nonresponse follow-up and the planned integrated coverage measurement sample design and estimation procedures for the 2000 census; recommending additional field tests and research to carry out in the near term and in the 2000 census; and reviewing the use of administrative records in the 2000 census. As required, the panel has issued two interim reports (National Research Council 1996, 1997b)

Chapter 3 reviews in more detail a number of Census Bureau decisions concerning how these activities are to be carried out in 2000 and what might be done differently in the 2010 census. Chapter 4 presents a discussion of three important technical criticisms in the statistical literature against use of integrated coverage measurement.

: · The Census Bureau has made and is making use of enhanced procedures for developing the address list to which the census forms are mailed. These procedures have involved efforts to build the address list throughout the decade (instead of relying solely on a rush effort as the census approaches, using sources of variable quality)

in the initial or standard census process. The integrated coverage measurement survey is very similar to the postenumeration survey conducted in 1990, but with two important differences: it is planned to be nearly five times as large, and the results are planned to be incorporated into the single set of official census figures rather than presented separately as an adjustment.

From page 11... ...
Nonresponse follow-up, integrated coverage measurement, and the placement of census forms in public places are designed to complement these two main steps by providing mechanisms for maintaining a high-quality census even when address list development and the mail return process understandably fall short of perfection. Collectively, the procedures are also designed to control costs, partly by increasing quality and thus reducing resource requirements for other aspects of the census process.

To acquire information and make final improvements on many aspects of the methodology and operations to be used in carrying out the 2000 census, the Census Bureau will use 37 separate studies based on the 1998 dress rehearsal. (A listing and short description of the 1998 dress rehearsal evaluation studies are given in the appendix to this chapter.)

The Menominee site used update leave/mailback and 100 percent nonresponse follow-up and tested an integrated coverage measurement program. Since the three sites were not comparable with respect to census processes, the various methods used across sites, specifically in Sacramento and South Carolina, cannot be compared directly.

Key Questionnaire-Related Evaluations With respect to the use of a replacement questionnaire, the key evaluation measurements are the percentage increase in mail response owing to its use and the effects on data quality of undiscovered duplicate responses and the cost of removing the duplicates that are discovered. Also, the percentage of telephone questionnaire assistance calls in which people complained about use of the replacement questionnaire gauges the extent of any negative public reaction.

Measurement of the net undercount rate in South Carolina was to determine the potential impact of adjustment for census undercoverage. Examination of the post-enumeration survey schedule in Sacramento helps the Census Bureau understand whether the goal of a "one number" census was operationally feasible (although the fact that a dress rehearsal is of a substantially different scale than that of a decennial census complicates the comparison to the timetable of a full decennial census)

From page 16... ...
(Clearly, due to the fact that dress rehearsals are carried out in a very small number of locations, they cannot fully test the ability to identify duplicate responses from geographically disparate areas.) Nonresponse Follow-Up and Field Infrastructure Evaluations One of the key variables in carrying out a decennial census is the amount of time necessary to complete field follow-up.

Summary The census dress rehearsal should give the Census Bureau a greater understanding of key issues: census operations, timing, costs, and logistics; the value of a blanket replacement questionnaire; the ability to hire effective field staff; the operational aspects of integrated coverage measurement, especially the schedule constraints; the use of CAPI instruments and the quality of the data collected; any problems with the census questionnaire; and any problems in developing the master address file.

to assess the quality of respondent-provided addresses collected during telephone questionnaire assistance operations; and (3) to determine whether forms mailed out through the telephone questionnaire assistance operation were completed and returned.

The first aspect of the error profile is to examine individually the sources of error corresponding to the enumeration process that are measurable and feasible to measure given the design of the Census 2000 Dress Rehearsal Integrated Coverage Measurement Survey. The second aspect of the error profile is to examine the net effect of a subset of these sources of error by estimating a net nonsampling error and combining it with the sampling, or random, error.

The five research projects are raking evaluation, evaluation of bias from integrated coverage measurement missing data methodology, heterogeneity/small-area estimation evaluation, householdlevel data file research, and mover estimation evaluation.

From the independent interview, erroneous enumerations will be calculated and omission rates for the specific rules evaluated. There is an operational component that will document the process used in the primary selection algorithm.

Was the Census Bureau able to hire, train, and maintain staff to execute nonresponse follow-up, integrated coverage measurement, and the post-enumeration survey? This evaluation is closely tied to G4 (pay rates)
