How does migration affect the population of a nation? what are the causes of migration?
Answers
Answer:
An important concern in immigration research involves the effects of immigration and assimilation on health, education, and social programs, particularly in areas of high immigration concentration. Much folk wisdom has viewed assimilation as a linear process of progressive improvement and adjustment to American society. The general assumption is guided by an implicit deficit model: to advance socially and economically in the United States, immigrants need to "become American" in order to overcome their deficits in the new language and culture. As they shed the old and acquire the new, they acquire skills for working positively and effectively—a process that may not be completed until the second or third generation after entry.
Explanation:
Contextual analyses of immigrants' integration experiences are an important area of needed information. In practical terms, this means that future national surveys of immigrants should not only permit subgroup analysis, but should also represent the social and economic spectrum of communities in which immigrants reside. Whereas assessments of economic well-being based on national samples are worthwhile for broad generalizations about income inequality among nationality groups, they are inadequate for portraying the contexts within which economic integration processes unfold. Widely discrepant conclusions about the extent and nature of labor market competition between native-born and immigrant people illustrate the need to reconcile findings based on specific labor markets and those based on nationally representative analyses. In fact, the high concentration of immigrants residing in a handful of large cities raises questions about the usefulness of analyses based on national populations.
