Industrialization is the process by which an economy is transformed from a primarily agricultural one to one based on the manufacturing of goods. Individual manual labor is often replaced by mechanized mass production, and craftsmen are replaced by assembly lines. Characteristics of industrialization include economic growth, the more efficient division of labor, and the use of technological innovation to solve problems as opposed to dependency on conditions outside of human control.
