Readers may be surprised to hear that Wilkerson conducted such extensive research yet chose to tell just three stories in her book. But this contrast only underlines her point: academic studies and statistics can never capture the “larger emotional truths” of the migration in the way that a few in-depth stories can. Thus, while she incorporates data and historical analysis, she focuses on the stories. She chose Ida Mae, George, and Robert not only because of their stories’ emotional poignancy, but also because they represent a diverse range of migration experiences. They migrate from different places to different places in different decades, and they also belong to different social classes and end up living dramatically different lives after they migrate. At the same time as these three protagonists capture the broad range of migrants and migration experiences, they also all represent the same core principle—migrating for freedom—that Wilkerson sees as both a universal norm and the specific core of American national identity.
