By the early 19th century the factory system had spread to the U.S. The first cotton factory was built in 1814, and by 1850 some 24 percent of workers were women. They produced clothing, shoes, cigars, and other things. In the Northeast, newly-arrived women with little education became the factory force. In the South, black women moved into factory and domestic（家庭的）jobs, first as slaves and later as free workers.

　　By 1890 nearly 4 million women in the U.S. worked for pay. This represented（代表）18 percent of the female population aged 14 and 17 percent of the total work force. Half the female workers were under 25 years of age, and seven out of ten were single. Most of them worked in domestic service, teaching positions, and textile（纺织的）factories; only about 5 percent were secretaries, clerks, or salespersons.

　　Recent years have seen a rapid increase in the number of women joining the paid labour force in the U.S. Today, almost 54 percent of all women of working age are employed. Over 50 percent of working women are married, and 60 percent of working wives have school--aged children.
