Final answer:
Following the Civil War, people migrated from farms to cities due to industrial expansion, advances in farming technology that lessened the need for rural labor, and an increase in factory jobs due to the Industrial Revolution. Despite challenging working conditions, the opportunity for employment drew many to the cities.
Step-by-step explanation:
After the Civil War, several factors led people to move from farms to cities. The most significant cause was the Industrial Revolution, with its factory system, which created numerous job opportunities. Advances in farming technology resulted in fewer jobs for rural populations as less manual labor was required for farming. Industrial expansion, driven by innovations like the transcontinental railroad, the telephone, and the light bulb, also played a crucial role in this mass migration. People were attracted to the cities due to the abundance of opportunities for work, especially in factories. The shift from craft industries and small shops to factories led to a transition from rural to urban living.
This change wasn't without drawbacks, however. Factory conditions were often hazardous and unsanitary, with workers forced to put in long hours for low wages. Despite these challenges, the progression towards urban populations and large-scale manufacturing was a key aspect of America's post-Civil War societal evolution.
