The ambivalent feeling of Americans toward immigrants is shown by a positive attitude toward groups that have been visible for a century or more, and much more negative attitude toward recent arrivals. For example, a 1982 national poll by the Roper Center at the University of Connecticut showed respondents a card listing a number of groups and asked, "Thinking both of what they have contributed to this country and have gotten from this country, for each one tell me whether you think, on balance, they've been a good or a bad thing for this country," which produced the results shown in the table. "By high margins, Americans are telling pollsters it was a very good thing that Poles, Italians, and Jews immigrated to America. Once again, it's the newcomers who are viewed with suspicion. This time, it's the Mexicans, the Filipinos, and the people from the Caribbean who make Americans nervous."
