Final answer:
American manufacturing in the late 1800s and early 1900s underwent significant changes, with a shift from an agrarian economy to an industrial one. This led to urbanization and immigration, transforming American society. Today, manufacturing in the US is more advanced and automated compared to the early 1900s.
Step-by-step explanation:
In the late 1800s and early 1900s, American manufacturing underwent significant changes. One major change was the shift from a primarily agrarian economy to an industrial economy, driven by the rise of industry and the development of commercial electricity. This led to an increase in urbanization and immigration, with more industries concentrating in cities and attracting newly arrived immigrants seeking employment in urban factories.
By the early 1900s, the number of industrial workers in the US had quadrupled, reaching over 10 million. Urban populations also doubled, making up half of the country's total population. These changes resulted in a transformation of American society, from primarily rural to significantly urban.
One key difference compared to today is the level of industrialization. While manufacturing still exists in the US, it has become more automated and advanced in terms of technology. The use of robotics and computerized systems has greatly increased efficiency and productivity in the manufacturing industry.
