Black voters helped pass an annexation that diluted their own electoral strength

Evidence

In 1950, however, the mayor introduced an ambitious “Plan of Improvement.” The plan called for the annexation of eighty-two square miles containing almost 100,000 people. It would triple the city’s size and boost its population by a fourth—almost all whites. Ironically, this time around, the “powerful minority vote” inside Atlanta proved to be the key to annexation’s success. Although the additional population would dilute their electoral strength, many black leaders supported the Plan of Improvement all the same. … With the endorsement of the legislature, the Plan of Improvement went into effect on January 1, 1952. As white coalition members had expected, Atlanta’s black population dropped from 41 percent of the total population to just 33 percent, literally overnight. — Kevin M. Kruse, White Flight, 96
