How has the recession impacted immigrants and where they choose to live? Do immigrants
learn English more quickly now than one hundred years ago? What impact have hurdles on the path to citizenship had on
Measuring Immigrant Assimilation in the United States
New York, NY: On Tuesday, October 6, the Manhattan Institute’s Center for Civic Innovation released its second
annual Index of Immigrant Assimilation authored by Duke University professor Jacob Vigdor. The index provides
the most detailed estimates to date of the assimilation levels of immigrant groups in the United States and also
serves to analyze what impact the recession has had on immigrants in the United States.
Last year, USA TODAY called the first edition’s calculations “among the most detailed so far to measure how well
immigrants fit in with native-born Americans on three fronts: economic, cultural and civic.” This year’s edition
provides more in-depth analyses of immigrant English language acquisition and the rates of naturalization in
The assimilation index is a quantitative measure based on a combination of decennial Census Bureau Data and the
annual American Community Survey. It measures the degree of similarity or distinction between the native-born and
foreign-born populations of the United States on a 0 to 100 scale. The index is recalculated annually with up-to-date
Key findings include:
- The economic downturn has contributed to the slowdown of the rate of immigration and has had a disproportionate
impact on immigrants relative to natives. While average immigrant growth since 1970 had been in the range of 3-4%,
between 2006 and 2007 it was only 1.4%. In 2007, the increase in foreign born population was only 500,000 compared
to 2.1 million in 2006. The economy slowed immigration rates, and caused a decline in cultural and civic assimilation.
- Mexicans immigrants continue to be the least assimilated ethnic group. The English skills of Mexican immigrants
are worse than the immigrant population as a whole though there is some evidence that their rate of English acquisition
may be higher. Relative to Mexican immigrants, Vietnamese arrived with a linguistic advantage and maintained that
advantage over time.
- Changes in policy have placed new hurdles on path to citizenship but immigrants remain just as likely to pursue
this path – illegal immigrants are a clear exception to the pattern. Indications are that immigrants from the late
1990s or early 2000s will have historically low rates of naturalization. There are several explanations, including
a higher proportion of recent immigrants ineligible for citizenship. Relative to the whole immigrant population,
naturalization rates for Mexicans are low while the rate for Vietnamese is high.
- Assimilation declined in the four largest destination areas – LA, NYC, Chicago, and DC. This might be another
effect of the economic slowdown. Assimilation increased in two other centers of Latin American and Caribbean
immigration – Miami and Houston.
- The rate of English learning among immigrants without any English skills appears lower than a century ago. The
immigrants of a century ago, arrived with poorer English skills, but acquired them at a significantly more rapid
rate than today’s immigrants.
Howard Husock, Manhattan Institute vice-president for policy research, said that the Institute has commissioned
the report because “it is important, as we consider any change in immigration policy, that we have reliable,
neutral information about the contemporary immigrant experience. The United States has, historically, been
successful at incorporating immigrants, economically and culturally; this Index will allow us to compare the
present situation with that of previous generations of immigrants.”
