What is the Third Sector? Definition and Key Features

The third sector is an umbrella term for organizations that operate outside both the public and private sectors. It includes any group that is not owned by the state and does not exist primarily to generate profit for shareholders or owners. Instead, these entities focus on addressing social, environmental, or community needs. You might also hear this group referred to as the voluntary sector, non-profit industry, or civil society.

These organizations fill gaps left by others. The government may lack the resources to address specific local issues. Private companies often ignore problems that do not offer a financial return. Third sector organisations step in to provide services and advocate for change. They make significant contributions to economic growth and social well-being.

The three pillars of third sector organizations

To be classified within this sector, an organization must meet specific criteria. It is not enough to simply be "kind." A formal structure distinguishes these groups from casual hobbyists or private businesses.

First, they are non-governmental. This means the state does not own or control them. While they frequently cooperate with government agencies and may receive state funding or commissions to provide public services, they remain independent. They maintain their own decision-making processes. Independence is vital.

Second, they follow a not-for-profit model. These groups must cover operational costs like rent, staff wages, and advertising. However, any financial surplus is reinvested into the mission. Money does not go to founders for personal gain. Every penny supports the stated goal.

Third, they are values-driven. Their work stems from a specific vision for improving the social or environmental landscape. This could involve human rights, education services, or climate change mitigation. They pursue goals that align with particular social perspectives. Mission comes first.

Taxonomy of the sector: key types of organizations

The third sector is vast and diverse. It contains everything from tiny community groups to massive international NGOs. Understanding these distinctions helps clarify how different entities achieve their aims.

Charities are perhaps the most recognizable group. They are set up for a specific cause and are governed by elected or appointed trustees. These trustees provide oversight to the Chief Executive. In very small charities, trustees might even take on hands-on roles. Funding often comes from public donations, grants from organizations like the National Lottery, or sales in charity shops. For example, Cancer Research UK funds scientific research while also supporting patients directly. Similarly, Age UK combats loneliness through counselling and social events.

Social enterprises function differently by running more like a business. They trade goods or services to generate income but exist with a clear community goal. All profits are reinvested back into the organization. Street Soccer Scotland is one example, as it delivers football-related services to disadvantaged young people. Social Bite is another, operating retail stores and catering while employing people from homeless backgrounds.

Community groups exist to provide specific services for local populations. They are non-profit making. All funds go back into the group to ensure continued operation. Local rugby clubs or golf clubs often fall into this category.

Other entities in this space include:

• Cooperatives that are owned and run by their members.

• Think tanks and private research institutes.

• Non-governmental organizations (NGOs) with international reach, such as UNICEF or Oxfam.

• Voluntary organisations providing local support.

Impact and the future of the sector

The third sector is a massive economic driver. In the UK, the sector contributed £17.1 billion to the economy in 2016/17 alone. It supports around 870,000 paid employees and over 20 million volunteers. This scale allows these groups to influence public policy through lobbying, advocacy, and research.

Many organizations use research to identify emerging issues. They may employ their own researchers or commission academic studies. This evidence is essential when they lobby politicians for systemic change. They also run public campaigns to shape perceptions on topics like pollution or poverty.

The role of these groups is shifting. Following the 2010 General Election, governments in some regions expected charities and voluntary organizations to take on more social and cultural functions previously handled by the state. This means third sector organisations increasingly provide essential services that were once strictly public responsibilities.

The future depends on partnership. Governments are working toward fairer funding commitments and better regulatory environments. As the world faces complex crises, the ability of these organizations to act quickly and locally remains vital. They bridge the gap between individual needs and state capacity. This work continues to grow every year.
