The United States Supreme Court ruling in the City of Richmond v. J.A. Croson Co. (Croson) and related case law provide the legal framework for conducting the Disparity Study. Specifically, Croson set the standard by which federal courts review both local and state government minority business enterprise programs.

The Court affirmed the longstanding legal precedent that programs employing racial classification would be subject to “strict scrutiny,” which is the highest legal standard.

Government agencies such as the City, under Croson, may adopt race-conscious programs only as a remedy for discrimination identified as statistically significant, and the remedy must impose a minimal burden upon unprotected classes.

The Court held that an inference of discrimination can be made prima facie if the disparity is statistically significant.

What Statistical Significance Means

If either the available prime contractors or the available subcontractors are underutilized, a statistical test is conducted to calculate the probability of observing the empirical disparity ratio or any less probable event. Thus, a test is performed to determine if a finding of underutilization is statistically significant
