Most small businesses are run by either a single person or a family.
Explanation:
Small businesses usually don't have an operational scope to hire employees and rely on either the skill set of the business owner or manufacture of a product that one person or a family can make.
Hiring of a staff comes with commitments of regular payouts and salaries which is not viable for many small businesses.
As these businesses are run by a single person, they are usually the sole source of their incomes as they would be putting in most of their working potential on the same.
