Text 6
The two principal ways in which immigrant groups adjust to the dominant culture of the host country are assimilation and acculturation. Some ethnic groups appear to have been almost completely assimilated, but Puerto Ricans remain a clearly identifiable minority community.
Puerto Ricans have followed the examples of previous immigrant groups by clustering in their own ethnic communities. They have created islands within a city where Spanish is spoken, native foods are available, Latin music is heard and other elements of the island life style are evident. The cultural familiarity of the barrio keeps many Puerto Ricans from leaving even when they can find better housing elsewhere, and this slows the process of assimilation.
Additionally, Puerto Ricans are a short plane trip from their homeland. There is a constant two-way flow between this country and the island that disrupts the assimilation process. And with the trend toward ethnic pride and cultural pluralism, pride in Puerto Rican cultural roots has been strengthened. Had the extreme anti-foreign sentiment of the 1940s persisted, Puerto Ricans may well have had to assimilate sooner, as did many other ethnic groups.
The term acculturation rather than assimilation would be used to describe the Puerto Rican experience on the mainland of the United Stated. Genuine assimilation has not taken place until an immigrant is able to function in the host community without encountering prejudice or discrimination. The problem of hostility in an alien world does not disappear with acculturation; there remains the painful reality of deprivation of status and social rejection.
