How did the sewing machine change the geographical concentration of garment production?
Answer
It moved production to urban centers where factories could access power sources
Because early sewing machines required power sources such as steam and eventually electricity, garment production could no longer remain dispersed in small homes and towns. The need for these power sources forced industry to centralize in urban centers, leading to the creation of large garment districts and contributing significantly to the growth and density of major cities.
