Achieving this will require countering fear of the unknown, especially among older whites, the only part of the white population that is projected to increase, and the one that votes. They need to be made aware that this dramatic demographic transformation is underway, and that it will benefit them. Investments in younger minorities — whom they may not yet see as their children and grandchildren — are crucial not only to the success of the nation's economy but also to future contributions to government programs like Social Security and Medicare.
The immigrants to the New World came largely from widely separated regions of the Old World . In the Americas, the immigrant populations began to mix among themselves and with the indigenous inhabitants of the continent . In the United States, for example, most people who identify as African American have some European ancestors, as revealed by genetic studies. In one analysis of those genetic markers that have differing frequencies between continents, European ancestry ranged from an estimated 7% for a sample of Jamaicans to ~ 23 % for a sample of African Americans from New Orleans, where there was historically a large class of mixed race (now called Louisiana Creoles ) (Parra et al. 1998).
