A measurement of the ratio R{sub b} = {Gamma}(Z{sup 0} {yields} b{bar b})/{Gamma}(Z{sup 0} {yields} hadrons) is reported. This measurement is made using the CCD-based vertex detector of the SLD detector at the SLAC Linear Collider. Efficient tagging of b{bar b} events is performed with an impact parameter technique that takes advantage of the small and stable interaction point of the SLC and all charged tracks in Z{sup 0} decays. In a sample of 27K Z{sup 0} events, a value R{sub b}=0.235{plus_minus}0.006{plus_minus}0.018 is obtained.
