Abstract: | In order to provide minorities with a realistic opportunity to elect candidates of their choice, an apparently obvious step is to create districts in which the minority equals half the population. A number of factors, however, make this a false equality. As a consequence, courts have used a "65 percent" rule, suggesting that equality of the voting population is achieved only when the overall population of a district is nearly two-thirds minority. We distinguish between this "equalization percentage" and the percentage needed to create a "safe" seat. We show that for blacks "equalization percentages": 1) are almost never as high as 65 percent; 2) vary widely across time and space; 3) have declined somewhat in the 1980s; 4) vary sharply between primaries and general elections; 5) are affected most heavily by the proportion of minority populations that is of voting age (or noncitizen) rather than by differences in registration and turnout. Election results further caution us that even when numerical equality in the voting population is appropriately calculated, such a population proportion is not always sufficient to elect minority candidates because of incumbency effects and differentially polarized voting. We argue that both packing blacks into overwhelmingly black districts and ignoring less tangible factors that hinder black electoral success are extremes to be avoided. |
