Interest groups are private associations of people who have similar policy views and who pressure the government to adopt those views as policy. One type of interest groups is cultural groups which consist of people bound in terms of religious beliefs, ideological goals or cultural demands. Economic groups are another prominent form of interest activity. As international trade increases, they try to influence their governments for support of their interests in other countries. Issue-oriented groups make up another category of interest. Interest groups have no formal policy-making authority, and must rely on those people within the government who do have such authority to translate their policy preferences into decisional outputs.
