Pressure Group:
Pressure groups are organized groups of individuals who seek to influence public policy and decision-making in order to promote their specific interests or causes. These groups are formed around common concerns and work towards achieving their objectives by exerting pressure on governments, political parties, and other decision-making bodies. Here are some key characteristics of pressure groups:

1. Organized Structure: Pressure groups have a formal organizational structure with leaders, members, and specific strategies for achieving their goals.

2. Specific Interests: Pressure groups represent the interests of a particular section of society, such as trade unions, environmentalists, or professional associations.

3. Focus on Influence: The main objective of pressure groups is to influence policy decisions rather than seeking direct political power. They use various tactics like lobbying, public campaigns, and media influence to achieve their goals.

4. Targeted Approach: Pressure groups primarily focus on specific policy areas or issues relevant to their interests. They aim to bring about changes in legislation, regulations, or government policies related to their concerns.

5. Limited Membership: Pressure groups often have a limited number of members who are directly affected by the issues they represent. This allows for greater cohesion and focused efforts towards achieving their goals.

People's Movement:
A people's movement, also known as a social movement or grassroots movement, refers to a collective effort by a large number of individuals who come together to bring about social, political, or cultural change. Here are some key characteristics of people's movements:

1. Mass Participation: People's movements involve a large number of individuals from diverse backgrounds who share a common cause or vision. They mobilize public support and participation through rallies, protests, and other forms of collective action.

2. Bottom-Up Approach: Unlike pressure groups, people's movements often emerge from the grassroots level and are driven by the collective power of ordinary citizens. They may not have a formal organizational structure or centralized leadership.

3. Broad Spectrum of Issues: People's movements can address a wide range of issues, including social justice, human rights, environmental protection, and political reform. They often challenge existing power structures and advocate for systemic changes.

4. Long-Term Goals: People's movements aim to bring about fundamental and long-lasting changes in society. They may seek to challenge established norms, policies, or institutions, and build public awareness and support for their cause.

5. Public Opinion and Activism: People's movements rely on public opinion and activism to create pressure on decision-makers. They often employ strategies like peaceful protests, civil disobedience, and grassroots organizing to mobilize support and achieve their objectives.

Conclusion:
While both pressure groups and people's movements aim to influence public policy and bring about change, they differ in terms of their organizational structure, membership, approach, and goals. Pressure groups tend to represent specific interests and work through targeted influencing tactics, whereas people's movements involve mass participation and seek broader social or political transformations. Both forms of collective action play important roles in democratic societies by providing a platform for citizens to voice their concerns and shape public discourse.
