And Africans?
2010 figures are not available yet, or maybe well hidden, but in 2000, of 18,000 Asians in Mississippi 70% were foreign born, half of these being citizens and almost half had arrived in America in the 90s [EDIT: of the foreign born that is, just noticed its not worded too well]; 5000 of them were living in Harrison County alone; 5500 of them were Vietnamese, over half of them living in Harrison, and about 3000 each were Indian, Chinese and Filipino. The Harrison County and Vietnamese subgroups had above-average US nativity rates and an earlier average arrival date, though a broadly average citizenship rate among the immigrant population.
Virtually no Asians in Mississippi spoke no English, but over 30% spoke it "well" or "not well" (as opposed to "very well"). That figure was almost 40% in Harrison County, and an actual majority among Vietnamese.
Didn't check for income stats.
