Factories and mines were not the only places where child labour was prevalent in the early 20th century. Home-based manufacturing across the United States and Europe employed children as well. Governments and reformers argued that labour in factories must be regulated and the state had an obligation to provide welfare for poor. Legislation that followed had the effect of moving work out of factories into urban homes. Families and women, in particular, preferred it because it allowed them to generate income while taking care of household duties.
