Social Change is different from Modernization, but social change can lead to modernization (it also can have the opposite effect). Social change, such as the civil rights movement in the 1960s, which mordernized the United States by eliminating segregation. Social change, such as the 1979 Iranian Revolution, had the opposite effect whereby the individuals living in that country were no longer as free or modern as other countries. Modernization requires there to be a base standard for comparison. For a group, country, or individual to modernize they must be changing towards something which is more modern than themselves by comparison. Currently the United States is modernizing it's health care policies, which could be considered a social change, in an effort to modernize with respect to Canada and other European countries. Social change, such as the introduction of communism in North Korea or Cuba, had the opposite effect of modernization.
