Single issue groups, also known as advocacy groups, are organizations that focus exclusively on a particular social or political issue. They are dedicated to promoting a specific cause or agenda through lobbying, media campaigns, and other forms of advocacy work. Synonyms for the term "single issue groups" include interest groups, pressure groups, cause-oriented organizations, and social movement organizations. These groups have a wide range of objectives and strategies, ranging from civil rights to environmental justice to public health. They play a crucial role in shaping public policy and raising awareness about important social issues. Despite their narrow focus, single issue groups can have a significant impact on social and political change.
