How Residential Segregation Affects Intergroup Contact and Prejudice
Quick fact
Studies show that people who live in more racially integrated neighborhoods report lower prejudice scores, even when their personal demographics are the same—suggesting that the neighborhood itself shapes attitudes.
Why this is interesting
Imagine two neighborhoods separated by a highway—one mostly white, the other mostly Black. Do the people on each side harbor more prejudice simply because they don't cross that line?

Understanding How Residential Segregation Affects Intergroup Contact and Prejudice
When groups live apart, they have fewer chances to interact. This lack of contact means that people rarely encounter counter-stereotypical examples, so they rely on simplified images from media or hearsay. Even when they do meet, those encounters are often formal or fleeting—like a brief exchange at a store—so they don't break down distrust. In contrast, neighborhoods with mixed housing foster repeated, casual interactions: kids play together, parents chat at bus stops, and neighbors help each other. These repeated contacts, under conditions of equal status and cooperation, gradually reduce anxiety and humanize the other group. The physical layout of a city—where houses are placed, how schools are zoned, where transit lines run—directly influences whether these natural contacts occur.
A deeper explanation
The mechanism works through two pathways: reduced opportunity and altered social norms. Segregation shrinks the pool of potential interaction partners, so the contact hypothesis—which states that under appropriate conditions contact diminishes prejudice—cannot operate. Even when occasional contact happens, it is often unequal (e.g., a service encounter) or competitive, which can reinforce stereotypes. Additionally, living in a homogeneous area signals that homogeneity is normal and desirable; residents internalize local norms about out-groups, sometimes without conscious awareness. This is why segregation doesn't just prevent friendship but actively fosters prejudice. The effect is robust across countries and ethnicities. For example, studies in Europe and the U.S. consistently find that individuals in segregated neighborhoods show higher out-group bias, even after controlling for income and education. The physical arrangement of homes becomes a psychological barrier, making it harder to see members of other groups as individuals.
