1. Sectional/Interest Groups:

• Represent the interests of a particular section of society, such as trade unions (representing workers), professional associations (e.g., doctors or lawyers), or business groups.
• Members typically benefit directly from the group's activities.

Example: The American Medical Association (https://www.ama-assn.org/), which represents physicians and advocates for their interests in healthcare policy.

2. Cause/Promotional Groups:

• Promote a particular cause or set of values that benefit the broader public.
• Membership is often based on shared beliefs or values rather than direct personal benefit.

Example: Amnesty International (https://www.amnesty.org/), which advocates for human rights worldwide.

3. Insider Groups:

• Have close relationships with policymakers and government officials.
• Often consulted by the government during the policy-making process.
• Tend to operate discreetly and use established channels of communication.

4. Outsider Groups:

• Do not have close ties to policymakers and may operate outside of traditional channels.
• Often rely on public campaigns, protests, and media attention to influence policy.
• May be more confrontational or radical in their approach.

5. Protective Groups:

• Aim to protect the interests of their members or a particular group in society.
• Focus on defending existing rights or privileges rather than promoting new ones.

6. Issue-Specific Groups:

• Focus on a single issue or a narrow range of issues.
• Can be either sectional or cause groups, depending on the nature of the issue.

Example: The Brady Campaign to Prevent Gun Violence (https://www.bradyunited.org/), which focuses on reducing gun violence in the United States.

7. Local Groups:

• Operate on a small scale and focus on local issues.
• May be concerned with planning decisions, environmental protection, or community services.
