Electricians are not super in demand, but the business is projected to grow 7% within the next ten years averaging 80,000 job openings a year.
Some places allow anyone to be able to do electrical work but in the larger cities most places require a licensed electrician to do electrical work.
An electrician can work in any area that requires their services all over the country.
