Final answer:
Child labor primarily applies to children between the ages of 5 and 14. Laws in the United States set limits on child labor and encourage schooling.
Step-by-step explanation:
Child labor is a widespread problem that primarily applies to children between the ages of 5 and 14. In the United States, laws were passed in 1938 to restrict the employment and abuse of child workers. These laws set limits on potentially dangerous jobs and set the age of workers at 18 to encourage schooling. For children aged 14-16, there are limited hours and restrictions on the type of work they can do.
