Inclusion means that people are able to take part without being left out. It applies to activities, schools, workplaces, and public spaces. Inclusion is supported by rules and policies in many countries.

In a classroom, inclusion may mean providing tools such as reading support or wheelchair access so all students can participate. Public spaces may include ramps, signs, or translation services. Inclusion can involve both physical access and social participation.

Inclusion is promoted by governments and organizations. It is part of education and community systems.
