How did changes in manufacturing in the late 1700s and early 1800s affect people living in cities in the north?

Changes in manufacturing in the late 1700s and early 1800s greatly affected people living in cities in the North in that an increase in manufacturing due to the Industrial Revolution led to a great increase in the number of jobs available, which increased the standard of living for many citizens.
