Discrimination is unfair action taken against others because they belong to a certain group.
It denies people benefits and opportunities that are necessary for a decent life, like jobs or housing.
Discrimination can flow from prejudice, negative stereotypes, or a failure to consider the needs of others.
Sometimes discrimination is deliberate and direct. For instance, discrimination can take the form of racist insults, sexual harassment, or the refusal to hire people because of their age or religion.
Discrimination can also be indirect or unintentional. One example is a public service or office that can only be reached by a flight of stairs. People who use walkers or wheelchairs will be unable to use the service, even though no one intends to exclude them.
