Assimilation is the process by which individuals from one cultural group merge, or "blend," into a second group. The concept of assimilation originated in anthropology and generally refers to a group process, although assimilation can also be defined and examined at the individual level.

Concepts Regarding Assimilation

The term "assimilation" describes a change in individual or group identity that results from continuous social interaction between members of two groups such that members of one group (often a minority culture group) enter into and become a part of a second group (often a majority culture group). In this process of assimilation, the minority group or culture may disappear by losing its members to the larger and more dominant cultural group. One of the more extreme forms of assimilation involves intergroup marriage (e.g., interracial marriage). Consider, for example, an immigrant Spanish-speaking Mexican woman who is Catholic marrying an English-speaking Anglo-American Protestant male. If the woman learns English, changes her maiden name and religion, and later becomes a U.S. citizen, she will have assimilated into mainstream American culture. While she does not necessarily need to change her religion and citizenship as the result of her marriage, if she were to make these changes while abandoning her native cultural ways, then this would be a case of full assimilation. In this case, entering another cultural group via marriage has resulted in a woman relinquishing most or all important aspects of her native identity. As part of this full assimilation, this person would undergo psychological changes in her cultural orientation (i.e., beliefs, attitudes, values), and in her cultural behaviors (i.e., customs, traditions) as well as in her personal identity, to the point of losing all or most of the traditions of her original native culture. A health-related question arises as to whether such an assimilation is socially and psychologically healthy. A century ago, scholars regarded such a complete change in identity and behavior—the "melting pot" notion—as a natural and necessary aspect of immigrant adaptation to life in the United States.

Historically, the melting pot notion has not progressed in its entirety within U.S. society, due in part to the presence of structural barriers, including prejudice and discrimination, that have limited some immigrant and native-born minority persons from significant access to the resources and privileges of the dominant social group. Moreover, within the United States some ethnic people have actively chosen not to "give up" their native heritage and identity, despite their desires to participate successfully within the American economy.

The process of assimilation is facilitated by education, and by conformity to the linguistic and most prevalent cultural norms that are valued within the dominant society. Within the United States, the dominant society (the "Anglo Saxon cultural value system") includes the values of individuality, freedom, democracy, and achievement orientation, efficiency and practicality, and science and technology. Thus, for immigrants coming to the United States, learning English is one of several adaptive changes necessary for successfully entering and participating in the social institutions of the dominant culture.

Historically, some ethnic minority groups have experienced a threat to their culture by the imposition of forced assimilation, resulting from governmental policies and programs that used education as a means of assimilating minority people. The classic case of this involves American Indians. Beginning in the 1890s, American Indian children were removed from the reservation and transported to Indian boarding schools where they were forced to learn English while they were also prohibited from speaking their native language. This effort to inculcate mainstream or dominant cultural ways and to eliminate minority culture, or "Indian ways," operated as a form of forced assimilation. Nonetheless, in the case of American Indians, this effort at "Anglo-Saxon conformity" failed to convert these American Indian children and their parents to dominant cultural norms, and subsequently these policies for the educational assimilation of Indians were discontinued. One question that arises, of course, is whether forced assimilation is detrimental to mental health.

Assimilation is to be distinguished from the related concept of acculturation. Both assimilation and acculturation refer to the process by which individuals undergo changes in their way of life through adaptation to pressures to conform to the lifeways of a new society. Acculturation, however, refers to changes in beliefs and behaviors that occur as an individual adjusts to life in a new culture. Level of acculturation has typically been measured by way of acculturation scales. Such scales typically consider: (1) the individual's level of proficiency in language (e.g., in speaking only Spanish, only English, or both); (2) prior life experiences within his or her native country; (3) current preferences regarding friends; (4) preferences regarding television and radio programs broadcast in English or in their native language; and (5) other aspects of cultural involvement.

While both assimilation and acculturation share a common process of adaptation, assimilation constitutes a more extreme form of change compared with acculturation. In other words, while acculturation involves changes in the individual's pattern of living in adapting to the new society, under acculturation the person often maintains some aspects of his or her original cultural ways and identity. As noted previously, with full assimilation the individual blends entirely into the new society losing most or all aspects of his or her previous cultural identity. By contrast, some immigrants develop a bilingual/bicultural identity, which involves the integration of language, beliefs, and behaviors learned from each of two cultures. This integrated bicultural identity is seen by some as a more mature and healthy resolution to the acculturative stress that affects many immigrants.

Assimilation, Acculturation, and Health

Public health research has examined the relationship between acculturation and health status. The results of these studies provide a mixed picture as to whether successful acculturation, and perhaps successful assimilation, can improve or denigrate health status. Generally, many studies have shown a positive relationship between a high level of acculturation and an increased number of health-risk behaviors that are prevalent in the dominant society. In other words, racial and ethnic minority populations have often observed a greater number of health-compromising behaviors as they acculturate into U.S. society. However, as many of these studies are cross-sectional in design, rather than longitudinal, this conclusion involving the apparent ill effects of acculturation has been inferred rather than observed directly.

In one line of health research—the Hispanic Health and Nutrition Examination Survey (HHANES) survey study of health status, which was conducted from 1982 to 1984—results generally showed the aforementioned association between levels of acculturation and various health problems. The association was stronger among women, although it was also apparent among men. Among Hispanic women, higher rates of health-compromising behaviors have been observed across levels of acculturation for cigarette smoking and for alcohol use. Moreover, for both males and females, a greater level of acculturation has been associated with higher rates of illicit drug use, particularly marijuana and cocaine. However, this general trend, when examined in greater detail, shows that the relationship between assimilation or acculturation and health status is very complex. For example, via the process of acculturation, individuals also tend to improve in socioeconomic status—which means better jobs, better insurance coverage, better access to health services, and, therefore, a greater likelihood of having better health.

Research on the influences of acculturation status on mental health and substance use further demonstrates the complexity of this relationship. For example, some researchers suggest that the occurrence of deviant youth behavior and subsequent substance abuse are prompted by the occurrence of acculturation stress among the parents coupled with subsequent parent-child relationship problems. Such problems often occur because immigrant children acculturate at a faster rate than their parents. Among adult immigrants, acculturation stress occurs as the result of the pressure toward conformity to dominant cultural ways that many immigrants experience in their effort to survive within a new country.

Others have argued, however, that the strong family orientation that is characteristic of Hispanic and other minority families serves as a protective factor against delinquency and other types of anti-social behavior. A clearer interpretation of these apparently contradictory findings will require greater depth of analysis regarding the sociocultural and familial factors that may add risk or protection to the lives of immigrants as they adapt to life within a new society.

A recent study of the lifetime prevalence of psychiatric disorders among various Mexican-American migrant laborers in California revealed some important relationships between acculturation and rates of psychiatric disorder. In comparisons of migrant laborers having a low level of acculturation with those having a high level, those having the highest levels of acculturation exhibited higher rates (adjusted odds ratios) of diagnosed mood disorders (depression) and of diagnosed drug abuse or dependence (addiction to illegal drugs). In addition, those migrant laborers who lived in the United States for less than thirteen years exhibited the lowest levels of any psychiatric disorder (lifetime prevalence rates), with higher levels observed for those who had lived in the United States for over thirteen years. Moreover, the highest levels of psychiatric disorder were observed among those who were native-born Mexican Americans. These results suggest that some process involving acculturative stress and/or adjustment to the normative living conditions within the United States increases the risk of depression and of illicit drug use among Mexican-American migrant laborers. Further developmental and longitudinal research is needed to clarify the mechanisms that may produce these effects.

From a different perspective, young immigrants who engage in deviant behaviors (including substance abuse) cannot be characterized solely as being of either high or low acculturation status, but instead can be seen as outcasts or "marginalized," because they do not "fit into" either group. Such individuals do not relate to either the dominant culture or to their native cultural group. In other words, these are persons who have failed to assimilate into the society. Such members of racial or ethnic minority groups may enter into socially deviant lifestyles in efforts to obtain coveted goals (e.g., economic rewards) that are otherwise blocked via conventionally sanctioned mechanisms (e.g., school achievement). These alienated youth may not only isolate themselves from the mainstream culture, but they may also become alienated from their native reference group. Isolated from both cultures, they may choose to become members of street gangs as a means of obtaining mainstream goals. While joining a street gang may serve as an adaptive form of survival in ghetto or barrio environments, it may be unhealthy in the long run, as these youth face greater risks of being victims of violence and of developing drug dependence. Similarly, minority youth who are alienated from the mainstream culture may develop a radical identity that avoids the mainstream culture but that expresses strong loyalty toward their native culture (i.e., separatists). These youth may or may not belong to a street gang, but they do exhibit strong cultural loyalty and adherence to certain traditional cultural traits such as (among Hispanic groups) family bonding (familism), respeto, and machismo.

As the above discussion suggests, acculturation (of which assimilation represents an extreme form) is a complex process. Many immigrants to the United States exhibit improvements in lifestyle as they acculturate and move up in socioeconomic status. However, as they do, some of these immigrants may also exhibit greater rates of unhealthful behavior, reflecting the prevailing or normative unhealthful behaviors that are prevalent within certain sectors of conventional U.S. society. These more complex patterns of change in lifestyle and in risk for various diseases and disorders due to acculturation and assimilation require further study to clarify which life changes are indeed healthful (and why they are healthful), and which increase the risk for disease or antisocial behavior.

Also known as acculturation, or integration, this is the integration of an immigrant, outsider, or subordinate group into the dominant, host community. Initially the migrant group is segregated from the host culture but then there is often a blurring of cultural lines, and the concept of assimilation does imply that the minority group eventually takes on the values of the host, or charter group. This contrasts with the view that new groups can affect the values of the dominant group, or live alongside it in a multicultural society.

The rate of assimilation depends on the race, religion, customs, occupations, and cultures of the migrants and the dominant group. Behavioural assimilation is the absorption of the incoming group into the host community, as the newcomers absorb the culture and history of the charter group, while structural assimilation is concerned with the way incomers are distributed throughout society, in occupational and social groupings. Urban geographers note that the degree of residential segregation is inversely correlated with the level of assimilation of urban immigrants.

1. In physiology, the incorporation of new materials into the internal structure of an organism.

2. In sociology, a process in which a minority group adopts the values and behaviour patterns of a majority group, and eventually become absorbed into the majority group. Compare accommodation.

3. A cognitive process in which children incorporate new experiences into their present interpretation of their world. The new experiences become part of the child's current conceptual schema, which therefore becomes fuller and more elaborate. If the new experiences cannot be assimilated, then the conceptual schema is changed (see accommodation).

Assimilation refers to the integration of the members of a minority group into the broader society to which they belong. According to the sociologist Milton M. Gordon, it is a seven-stage process, in which "acculturation," or the adoption by newcomers of the language, dress, and other daily customs of the host society, is the first step. "Structural assimilation," the second, involves the large-scale entrance of minorities into the cliques, clubs, and institutions of the host society, in a manner that is personal, intimate, emotionally affective, and engaging the whole personality. Once a group has achieved structural assimilation, the remaining stages "naturally follow." Those include "amalgamation" or frequent intermarriage, the development of a sense of peoplehood based solely on the host society, the disappearances of prejudiced attitudes and of discriminatory behavior toward the minority, and the absence of civic conflicts in which the competing interests of the majority and minority groups are an issue.

Assimilation is a problematic term. It can refer to the experiences of a group or of its individual members. Originating in the natural sciences, it identified a process through which one organism absorbs another; the latter then ceases to exist in recognizable form. Scholars are vague about the techniques for measuring the progress of assimilation and imprecise in defining its practical completion short of the disappearance of the minority, which rarely occurs. Some focus on socioeconomic adjustment and demographic behavior, while others emphasize changes in identity. Advocates with differing political agendas regarding national development debate whether assimilation is a desirable outcome for a society containing multiple groups.

Theorists have given names to existing, implicit models of assimilation and have proposed alternative ones. Identifying the boundaries that separate terms such as "melting pot," "pluralism," "cultural pluralism," and "multiculturalism" is not easy. The use of ancillary concepts, including "Anglo-conformity," "triple melting pot," "primordial ethnicity," "symbolic ethnicity," and "postethnicity" further complicates discussions.

The Melting Pot

In the 1780s, Hector St. Jean de Crèvecoeur offered one of the earliest descriptions of the formation of the American population as the physical melding of diverse European peoples into a new, single people. Israel Zangwill's eponymous 1908 play made "melting pot" the twentieth century's phrase for Crèvecoeur's idea. An English Jew who espoused various forms of Zionism throughout his life, Zangwill nevertheless presented, as the outcome of life in the American cauldron, the union of seemingly implacable enemies—a Russian Jewish immigrant to New York and the daughter of the tsarist official who had ordered the destruction of his village.

Although melting pot implies mutual change leading to the creation of a new alloy, most who adopted the phrase described a process, which Milton Gordon later called "Anglo-conformity," through which newcomers adapted to norms derived from an Anglo-American heritage. Alternative visions arose almost immediately. In 1915, Horace Kallen described the United States as an orchestral combination of constant European cultures. Cultural pluralism, as Kallen's outlook became known, rejected the melting pot and described ancestral roots as so determinative that Americanization had to be repeated with each generation. Writing as an opponent of U.S. involvement in World War I, Randolph Bourne critiqued the melting pot ideal as the effort of Anglophiles to place their own culture ahead of others and envisioned Americans sifting and winnowing the best from all traditions. Unlike Kallen, Bourne implied greater mutual change among the nation's constituent groups, with residual differences being of little consequence. Bourne's phrase, "trans-national America," has not survived, but the term "pluralism," or some variant of it, has captured the spirit of his ideas.

The melting pot metaphor, especially as expressed by proponents of "100-percent Americanism," held sway through World War I and after. As of the New Deal and World War II, however, concepts like "cultural democracy" and versions of cultural pluralism closer to Bourne's point of view than to Kallen's became predominant. Under the influence of thinkers like the sociologist Robert E. Park, the criteria for assimilation became political loyalty, adoption of generally accepted social customs, and conformity to national practices and aspirations.

As limited immigration changed the demographics of America's foreign stock after the 1920s, the Great Depression, World War II, cinema, radio, and eventually television spread generations of common experiences across the nation. By the 1940s, the sociologist Ruby Jo Reeves Kennedy argued that a "triple melting pot" had emerged. Clear ethnic boundaries were disappearing, as Protestants, Catholics, and Jews willingly married across nationality groups but within their religious traditions.

Religious Segmentation

Religion's potential for segmenting the population was a source of concern. Paul Blanshard accused Catholics of hostility to America's democratic and liberal traditions. Several observers noted the lagging socioeconomic status of Catholics, and Gerhard Lenski attributed the gap to values rooted in the religion. Overall, however, the triple melting pot was simply an elaborated expression of the benign pluralist model of the era. Will Herberg, in Protestant, Catholic, Jew: An Essay in American Religious Sociology (1955), argued that the nation's three major religions shared the political and civil values that made the United States the world's leading theistic power. Subsequent scholarship indicated that, on average, foreign-stock Euro-Americans had "caught up" by 1950. For those seeking reassurance, the election of John F. Kennedy, a Catholic, as president offered evidence that differences based in religious background had waned.

Race Succeeds Religion

The issue of race was peripheral to the assimilation debate in the first half of the century. With the rise of the civil rights movement, however, race succeeded nationality and religion as the final frontier of America's assimilation history. Drawing from works like Stanley Elkins's Slavery: A Problem in American Institutional and Intellectual Life (1959), liberals assumed that slavery had deracinated blacks and made them the most culturally American of all the peoples who had come to the New World. Color prejudice, therefore, was the primary obstacle to total assimilation.

This optimism waned when dismantling discriminatory legislation proved an inadequate means to achieve rapid structural assimilation for black Americans. Critics argued that the legacy of slavery and the visibility of color differences made it impossible for racial minorities to attain assimilation of the kind achieved by Americans of European origin. They denied that blacks had reached the status of an "interest group," which Nathan Glazer and Daniel Patrick Moynihan saw as the remaining function for group identity among the Irish, Italians, Jews, blacks, and Puerto Ricans of New York City. Rediscovering ties to Africa, or reinventing them, activists posited the existence of true cultural differences separating blacks from the majority in the United States. Similar developments occurred among smaller minority populations, including Native Americans, Latinos, and Asians who had experienced discrimination analogous to that suffered by blacks.

The Revival of Multiculturalism

After the 1960s, Kallen's version of cultural pluralism, which the author himself had long since abandoned, enjoyed a revival, often under the term "multiculturalism." Although some commentators used the word simply as a synonym for the view of pluralism dominant at midcentury, others offered multiculturalism as a distinct alternative. They saw ethnic and racial identities as primordial or ineradicable; accepted the existence of real and permanent cultural differences; vested the strength of the United States in its diversity, which the government, therefore, had an obligation to preserve; and stressed the importance of group as well as individual rights.

Multiculturalism did not escape criticism, especially when its proponents reduced American diversity to a split between Europeans and allied "peoples of color," and, in an era of renewed immigration, not only predicted what the future would be but also offered policy prescriptions for what it should be. Although Asian and Latino newcomers to the United States in the late twentieth century had direct or indirect ties with groups that had suffered prejudice on the basis of ascriptive characteristics, they arrived in an era when the nation had rejected discrimination based on such grounds. They constitute majorities in the minority groups to which they ethnically belong, and the empirical evidence leaves it open to debate whether their experiences are replicating the history of exclusion associated with race or the history associated with the integration of European immigrant groups.

Michael Novak, in The Rise of the Unmeltable Ethnics: Politics and Culture in the Seventies (1972), adopted some multicultural premises but used them to demonstrate that Europeans from quadrants outside the northwest of that continent suffered exclusions similar to those experienced by racial minorities. Arthur M. Schlesinger Jr., in The Disuniting of America (1991), and Nathan Glazer, in Affirmative Discrimination: Ethnic Inequality and Public Policy (1975), more thoroughly disagreed with the contentions of the multiculturalists and with the various programs they endorsed to preserve minority cultures and to promote access to education and employment for minority group members.

Moderate commentators have sought to find themes that may lead to a generally accepted interpretation of assimilation. Although cognizant of the real experiential differences between the heirs of European immigrants and descendants of African slaves, Matthew Frye Jacobson, in Whiteness of a Different Color: European Immigrants and the Alchemy of Race (1998), demonstrated the overlap-ping histories of the terms "race" and "ethnicity" and the constructed rather than substantive meanings of both. Herbert Gans has claimed that for Americans of European descent ethnicity is primarily a "symbolic" identity that they can use voluntarily and in positive ways. Ann Swidler has similarly described ethnicity as just one of the cultural tools through which persons can express their identities. David Hollinger, in Postethnic America: Beyond Multiculturalism (1995), argued for a future in which all persons can comfortably claim one or more ethnic identities without having their expectations or behaviors limited by those identities.

The process by which a person or persons acquire the social and psychological characteristics of a group: “Waves of immigrants have been assimilated into the American culture.”

Conversion of nutritive material into living tissue; anabolism.

It has been suggested that this article or section be merged into Borg (Star Trek). (Discuss)

In the Star Trek fictional universe, assimilation is the process by which the Borg, a race of cyborgs, integrate beings and cultures into their collective. This philosophy is reflected in one of their maxims, which they typically utter before incorporating a culture: "You will be assimilated."

When they debuted in the television series Star Trek: The Next Generation, the Borg were a mysterious group of marauders that snatched entire starships or took over entire planets and societies in order to collect and assimilate their technology ("Q Who?"). In their second appearance, "The Best of Both Worlds", they also began to rather crudely and frighteningly assimilate individuals – namely, Captain Jean-Luc Picard of the starship Enterprise – into their collective by surgically altering them. Using his knowledge of Federation technology and strategy, a single Borg cube destroyed a flotilla of 39 Starfleet vessels in the Wolf 359 system that were assembled to halt the Borg advance toward Earth. Thereafter, incorporation of different lifeforms into their collective was heightened and their interest in obtaining alien technology became merely one of two objectives.

Moreover, the method of assimilating individual lifeforms into the collective has changed over time. Throughout, infant and fetal humanoids have been grown in an accelerated state and surgically receive or develop implants tied directly into the brain, as well as ocular devices, tool-enhanced limbs, armour, and other prosthetics.

Nanoprobes

Later, in the movie Star Trek: First Contact, the method of assimilation was enhanced with the more efficient injection of nanoprobes into individuals. Borg nanoprobes are injected into the bloodstream of a victim by a number of tubules (usually two) that spring forth from the top of the hand or some other extremity of a Borg drone. The nanoprobes, each about the size of a human red blood cell (RBC) and employing nanotechnology, travel through the victim's bloodstream to various biological tissues and locations throughout the body and latch onto individual cells. The nanoprobes rewrite the cellular DNA, altering the victim's biochemistry, and eventually form larger, higher structures and networks within the body such as electrical pathways, processing and data storage nodes, and ultimately prosthetic devices that spring forth from the skin.

Once within an organic host, nanoprobes utilize metallic molecules from humanoid blood cells (e.g., iron from humans, or copper from Vulcans) to replicate and create higher structures. To that end, Borg nanoprobes are capable of adjusting the atomic structure of metals and molecules, creating ones more appropriate for Borg prostheses and nutrients essential for humanoid survival. Breaking down RBCs would cause asphyxia in the victim, also aiding in their submission to forces prior to full assimilation. This also alters blood vessels throughout the body, creating visibly dark tracks that snake across the surface of the skin as the cyberinfection spreads. Based on the size of a single nanoprobe and the volume that could be delivered in the short time of a drone attack, a single injection can carry at least five million nanoprobes.^{[citation needed]}

Assimilation is the main way for the Borg to gain information about a new species, i.e. a species of which no individuals have been previously assimilated by The Borg. The Borg are less skilled in investigating; gaining information about species before they are assimilated (source: Episodes “Scorpion Part 1 & 2” from ST:VOY). Nevertheless, they are remarkably efficient at both - in the episode Q Who, they were able to easily discover enough about Federation technology to render the Enterprise’s defensive capacities neutral, though they are not known to have assimilated anybody (however, eighteen crewmembers went missing when the Borg sliced a segment out of the Enterprise and brought it aboard their ship).

Because biological assimilation depends on nanoprobes, species with an extremely advanced immune system such as Species 8472 are able to withstand assimilation (due to this, coupled with the fact that Species 8472 uses no artificial technology, the Borg could not develop any effective methods of fighting against them).

In the ST:VOY episode “Drone,” the Doctor’s mobile emitter (obtained from the future in the episode “Future’s End, Part 2”) combines with Seven of Nine’s technology to form a 29th century version of a Borg drone. Its capabilities included an internal transporter, improved speech capabilities, multidimensional adaptability, and greatly improved personal shields. Fortunately for Voyager, this drone’s enhanced capabilities were not assimilated by the Borg Collective; the drone, in fact, sacrificed itself to save Voyager’s crew.
