ABSTRACT
Diversity and segregation are not the same thing. They are measured differently and are only modestly correlated. More critically, diversity measures tell nothing about how close people of different backgrounds live to each other. Diversity is a measure of potential isolation. The commonly used measure of fractionalization indicates the probability that members of different groups interact with each other. Diversity is important in moderating the connection between integrated neighborhoods and trust in the United States. The dissimilarity/entropy indices tell the share of people who have to move to make a neighborhood representative of the larger community. For most people, trust is developed early in life learned from one's parents and stable over time. In some countries, immigrants are highly trusting, when there are strict criteria for education and training to admit them to their new country, as in Canada or Australia. Negative attitudes toward diversity are mostly confined to the majority population.
