Review- Hirschman's theory of exit, voice, and loyalty

To put it simply:

Exit- When people leave a community because different ethnic groups than their own are moving in, or because they fear this will happen. They do this for a variety of reasons. Sometimes the neighborhood is just a stepping stone to a better one and sometimes it's because they fear a higher crime rate or declining property values.

Voice- When a neighborhood speaks their opinions on different ethnic groups moving in. This can be either good or bad. Sometimes it's good when the people are being accepting or they want to understand the other group. Usually it's not such a great thing because people are speaking out against the other group (not extremely overtly) or rallying everyone to "stay strong" and what not and they're busy being "the last stand" or whatever. It can also be people refusing to accommodate other ethnic groups in business, religion, or education.

Loyalty- How likely the people are to leave the neighborhood. If they have a lot of loyalty they won't. If they don't have a lot of loyalty, they will. However, this can lend itself to loyalty to the old neighborhood when it's changing, which can be counterproductive and will make integration that much harder.
