It is estimated that, by 2050, African Americans, Hispanics, Asians/Pacific Islanders, and American Indians will account for 47 percent of the American population. It is also estimated that the proportion of elderly Caucasians will decrease from 84 percent in 2000 to 64 percent in 2050, while the proportion of African Americans will double and the proportion of Hispanics will triple over that same time period (Himes, 2001).
