an area outside a large city, where many rich people live （大城市外围的）富人住宅带 CultureMany of the people who live in the stockbroker belt work in the city as highly paid professional people, for example stockbrokers (= people who buy and sell shares in companies for other people). Most people think of the typical stockbroker belt as Surrey, south-west of London, but the phrase can be used to refer to any expensive area outside a city.
