Pressure Group vs. Interest Group: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 8, 2023
Pressure groups actively lobby to influence policy in their interest area; interest groups focus on common interests and may not actively lobby but engage in awareness and education.

Key Differences

Pressure Groups are organizations formed to influence government policy or legislation. They are proactive in lobbying and often have a focused, specific agenda. In contrast, Interest Groups might not be as aggressive in lobbying; they are more about uniting people with common interests, potentially including, but not limited to, influencing policy.
Interest Groups represent a broad range of interests, from professional to social issues, focusing on education and advocacy within their domain. On the other hand, Pressure Groups usually have a narrower focus, aiming to effect change in specific policy areas, and employ direct lobbying techniques.
Pressure Groups often engage in campaigns, demonstrations, and direct lobbying to exert influence on decision-makers. Conversely, Interest Groups tend to involve themselves in research, education, and networking activities to support their members' interests and raise awareness.
Interest Groups can encompass a wide array of members, from professionals to hobbyists, and their activities can be varied. Meanwhile, Pressure Groups are typically more homogenous, rallying around a specific cause or issue with the intent to bring about legislative or policy change.
While Pressure Groups are known for their intensive efforts to sway public opinion and policy, Interest Groups are often more focused on educating their members and the public, and providing resources and support related to their interest areas.
