other evidence bearing on the presence or absence of discrimination in employment.
The district court received into evidence and considered the statistical data as well as the other evidence offered, including much oral testimony, and determined that the record before it did not show discrimination on the part of ESB. The district court especially noted that the office force and the supervisory and salaried positions might arouse suspicion and that on a different record a finding of discrimination might be justified. But the court properly decided the case on the record before it, not its suspicions. It took care to provide, as do we, that the class plaintiffs are not adversely affected by the failure of the individual plaintiffs to establish their claim for them.
If we consider that the statistical evidence called to our attention by the plaintiffs makes a prima facie case, we are of opinion that the whole statistical evidence does not, or, to put it another way, if the plaintiffs’ prima facie statistical case has been made, it has been rebutted by other statistical evidence as well as the absence of other evidence of discrimination. We think the finding of the district judge in this respect is not clearly erroneous, and, with two exceptions, a more detailed discussion of the statistical evidence is made elsewhere in the opinion.
We do not believe either Brown or Barnett require a different holding for the reasons we have set forth above and the brief comparison which follows.
In Brown, black workers were employed in only 11 job classifications out of 45. Here, blacks were employed in 73 and whites in 83 of 115 job classifications. Blacks were employed in 24 of the 26 departments in September 1972. In Brown, slightly less than half of the black employees were employed near the bottom of the company’s pay scale. Here, at the bottom of the pay scale, the division between whites and blacks is almost exactly 50%. And leaving out the craftsmen, about which more will be said later, black employees are spread throughout the operating force of the company and employed in 10 of the 11 pay grades. In Brown, there was a lower percentage of black employees than the percentage of black people in the general population; here, there are more. In Brown, see p. 1383, there was no objective standard for promotion based on “education, experience, ability, length of service, reliability or aptitude.” Here, promotion is based on “proven ability, proper qualifications, sufficient experience, and length of service.” Here, all other things being equal, length of service controls. While in Brown we held that failure to post notices of job vacancies was a badge of discrimination which served to corroborate statistical evidence, here the percentage of promotions received by black employees was slightly larger than their percentage in the work force. So, so far as the record before us shows, there is no statistical imbalance in promotions, and thus no adverse inference, for the absence of job postings to corroborate. We do not mean to imply that absence of job postings may not be evidence of discrimination, and we do not so hold.
In Barnett, black employees were in only one of 17 non supervisory job classifications; here, black employees worked in 73 and white employees in 83 of 115 job classifications. As noted, blacks were employed in 24 of the 26 departments in September 1972. In Barnett, there were no black supervisors, as here, but we must assume, for the opinion does not indicate it, in view of our holding in Patterson, above referred to, that their availability in the work force was not before the court in Barnett. More will be said of this later. In Barnett, the percentage of black employees in the plant was less than that in the general population; here, it is greater. In the job at issue in Barnett, over-the-road driver, there were no black employees out of 27. No such claim is made here. In Barnett, there was word of mouth hiring for over-the-road drivers as contrasted to open recruiting for other jobs. Such is not present in our case, and the defendant here is not shown to have any different hiring policies.
Thus, in the case before us, we do not find a statistical imbalance indicating “that
