A new study conducted in the United States reveal that Asian immigrants have a higher income level than white Americans and often tend to live in highly segregated enclaves.
The nearly 18 million Asian immigrants to the United States are the country's fastest growing minority group, more than doubling since 1990, said the research by Brown University.
Data from the US Census provided a snapshot of the Chinese, Indian, Filipino, Japanese, Korean and Vietnamese living in the United States and how trends have changed.
The report, "Separate but Equal: Asian Nationalities in the US," found that Indians and Japanese were the most economically advantaged nationalities, while Vietnamese had the lowest incomes and the least education among Asian groups.
Still, Vietnamese tended to live in neighborhoods that were about on par with average whites, said the report.
Every other Asian nationality lived on average in neighborhoods with higher incomes and more college-educated residents than non-Hispanic whites did, it said.
"We are so aware of the disadvantaged situation of blacks and Hispanics that we tend to assume that segregation results in unequal neighborhoods for minorities," said John Logan, a sociology professor at Brown University.
"This isn't the case for any major Asian nationality. And that means there is very little incentive for Asians to assimilate into white neighborhoods."
Chinese were the single largest national group, with more than four million people or a quarter of the Asian total, followed by Filipinos (3.4 million) and Indians (3.2 million).
"Indians and Japanese are the more advantaged nationalities, while Vietnamese have the highest unemployment, lowest income, and least education among these groups," said the report.
Indians had the highest median household income among Asians, at $89,600 in 2010 compared to non-Hispanic whites at $54,000. Filipinos were second highest, followed by Chinese and Japanese.
"Asians live separately but in some respects they live in better than equal neighborhoods compared to whites," said the report.
"Although there are variations among the Asian national origin groups (with Vietnamese living generally in the least affluent neighborhoods, and Japanese, Koreans and Indians in the more affluent areas) the findings are similar for all groups."
Los Angeles and New York have the highest number of Asian immigrants, with nearly 1.5 million in each metro area.
