An interest group is an organization of people who share common goals and actively seek to influence public policy to achieve those goals. These groups can represent various interests, such as environmental protection, business interests, labor rights, or education. They often engage in activities like lobbying, campaigning, and public outreach to persuade lawmakers and the public. Interest groups play a significant role in the political process by providing information, mobilizing citizens, and advocating for specific issues. Examples of interest groups include the Sierra Club for environmental issues and the National Rifle Association for gun rights. Their efforts can shape legislation and public opinion.
