The Commonwealth has programmes for training and education, sharing technology and scientific understanding and improving people's living conditions.
The Commonwealth emphasises equality, trust and understanding.
Over the years the Commonwealth countries have made declarations, which everyone agrees to. The Harare Declaration (1991) for example, stated that all countries were committed to democracy, the rule of law and good governance. Sometimes countries are suspended (or excluded) from the Commonwealth by not standing by these declarations.
It works to improve the lives of Commonwealth people. It does so in such areas as education, housing, clean water and health.
