Measurements are reported of the Hall coefficient {ital R}{sub {ital H}} and {ital ab}-plane resistivity for single-crystal Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8{minus}{ital x}}, with variable oxygen configuration. As the system is driven through the metal- insulator'' transition, {ital R}{sub {ital H}} increases strongly but continues to obey the empirical expression 1/{ital R}{sub {ital H}}={gamma}+{beta}T, where {ital T} is the temperature. For low oxygen content the Hall mobility {mu}{sub {ital H}} becomes temperature independent. We examine these results in terms of various normal-state transport models.
