The Warmth of Other Suns: The Epic Story of America's Great Migration

by Isabel Wilkerson

Yet the hardened and peculiar institution of Jim Crow made the Great Migration different from ordinary human migrations. In their desperation to escape what might be considered a man-made pestilence, southern blacks challenged some scholarly assumptions about human migration. One theory has it that, due to human pragmatism and inertia, migrating people tend to “go no further from their homes in search of work than is absolutely necessary,” Ravenstein observed. “The bulk of migrants prefers a short journey to a long one,” he wrote. “The more enterprising long-journey migrants are the exceptions and not the rule.” Southern blacks were the exception. They traveled deep into far-flung regions of their own country and in some cases clear across the continent. Thus the Great Migration had more in common with the vast movements of refugees from famine, war, and genocide in other parts of the world, where oppressed people, whether fleeing twenty-first-century Darfur or nineteenth-century Ireland, go great distances, journey across rivers, deserts, and oceans or as far as it takes to reach safety with the hope that life will be better wherever they land.
