In California, citing testimony from Computer Professionals for Social Responsibility and others, a judge for the Public Utilities Commission recently suggested that CNID
be disallowed in that state on the grounds that it violates people's right to control the disclosure of personal information, and called upon the telephone companies to develop services that are more useful to residential phone users.
In a case with harrowing testimony on the effects CNID can have on women's safety, the PUC proposed a new Random False Identity Service to protect domestic violence shelters and volunteers.
Some valuable new services may result from these CNID hearings, and many serious privacy problems will be avoided.
As the CNIDS was conducted in August 1995, the March 1995 CPS provides the best available estimate of the joint distribution of gender, age, and education in the U.
Since characteristics other than gender are likely to be useful for adjustment, [TABULAR DATA FOR TABLE 4 OMITTED] we reviewed which correlated demographics in the CNIDS interview - age, gender, education, and income - would also pass the consistency test and would be comparable in the CNIDS and the 1995 Census data.
The CNIDS raw data, when weighted using the Project 2000 weights, has three properties:
One additional factor that may contribute to the statistical problems with the CNIDS weighted sample, besides a deficient weighting scheme, is the cooperation rate, calculated as the percentage of eligible individuals who agreed to participate in the survey.
The sample cooperation rate for the CNIDS was not publicly released but is reported in the proprietary Final Report , available for a fee from the CommerceNet Consortium or from Nielsen Media Research.
The CNIDS estimates of Internet and Web use are logically inconsistent because individuals saying they used the Internet in one question only to later say they did not use the Internet were included in counts of use.
The effect of reweighting the CNIDS raw data is shown by comparing columns (b) and (c) in Table 2.
For example, column (b) shows that CNIDS estimates 16.
