>In the short run, however, immigration and ethnic diversity tend to reduce social solidarity and social capital. New evidence from the US suggests that in ethnically diverse neighbourhoods residents of all races tend to ‘hunker down’. Trust (even of one's own race) is lower, altruism and community cooperation rarer, friends fewer.
There's plenty of secondary sources reporting on this study if you want to have a look for the varying opinions on it but I thought I'd link the source of it itself.
Whether less trust, less cohesion etc. == more racism is something I'm not in a position to draw a conclusion over, but it's interesting nonetheless.
If trust of one's own race is lower also, this seems unlikely to be a consequence of ethnic diversity per se. Rather, I would speculate that, due to the tendency of people to group with their own race, more diverse neighborhoods simply tend to be more transient neighborhoods - places where people are "just passing through" and not really there by choice. There is no point attempting to build community bonds in an area with high churn, and that you yourself plan to move out of at the soonest opportunity.
