The informal sector is like a big group of people who do jobs that do not involve any kind of official paperwork. They usually do not have bosses or a business. People in the informal sector may trade goods or services, such as a street vendor selling food, a hairdresser doing someone's hair, or a odd jobs person fixing things in a home. People in the informal sector usually earn less money than people in formal jobs and may not receive the same benefits, like health insurance, vacation time, or retirement savings.
