are of a consistently high quality. These measures should include the establishment of effective procedures for developing and evaluating survey questionnaires and the aggressive pursuit of strategies for increasing the response rate for the monthly household survey. Reducing the frequency of the household survey from monthly to quarterly merits consideration because of the possible resulting improvements in survey quality. The committee further recommended that BTS take steps to ensure that its analyses of Omnibus survey data are technically robust and that the resulting products comply with established guidelines for the reporting of statistical data.

The next chapter draws on the outcomes of the committee’s reviews of individual surveys, together with the evaluation framework described in Chapter 1, to identify seven major themes pertinent to BTS’s current survey programs. In addressing these themes, the committee’s conclusions emphasize crosscutting issues relating to the NHTS, the CFS, and the Omnibus program.
