Discrimination is the unfair or unequal treatment of individuals or groups based on characteristics such as:
• Race or ethnicity
• Gender or sex
• Age
• Religion
• Disability
• Sexual orientation
• National origin
• Social class
It occurs when people are denied opportunities, rights, or fair treatment because of these traits rather than their abilities, behavior, or qualifications.
