This paper is on America as a melting pot due to the assimilation of immigrants in America. Today, huge numbers of Americans are of mixed cultures. Many do not fit the limiting categories of race such as White, Black or Negro, American Indian or Alaskan Native, and Asian or Pacific Islander -- outlined in Statistical Directive 15, which was adopted in 1978 by the Office of Management and Budget and used in the 1990 U.S. Census of the Population. A rising number of Americans are "Multiracial-Americans." This making the term "melting pot" even more appropriate. The people of this country are most of a mixture of several different cultures; the backgrounds of our citizens cannot be reduced to one label or another. To be "American" now means a "melting" of several different ethnic categories.
