Final answer:
The charts showcase the stark increase in the urban population as a result of industrialization, indicating that economic opportunities in cities resulted in significant migration and urbanization.
Step-by-step explanation:
The result of industrialization best represented in the charts above is that economic opportunities caused masses of people to move to cities. Throughout the United States, the rise of factories powered by steam and then by commercial electricity transformed urban centers into hubs of industrial activity.
Thus, populations in cities like New York, Chicago, and Philadelphia soared as newly arrived immigrants and former rural workers flocked to these burgeoning urban areas seeking employment in the new urban factories.
This urbanization coincided with the second half of the nineteenth century, driven by industrialization which required a large workforce for factories that could now operate continuously thanks to new technologies like electric lights and powerful machinery.
