Which factor drew farm families to northern cities in the late 1800s?

In the late 1800s, many farm families were drawn to northern cities primarily due to the promise of better economic opportunities and jobs in industrial sectors. The rise of factories and the demand for labor in urban areas offered a chance for higher wages compared to the struggling agricultural economy. Additionally, advancements in transportation, such as railroads, made it easier for families to relocate and access urban markets. The allure of improved living standards and educational opportunities also contributed to this migration trend.
