The correct response that evaluates the cause of increased migration to the U.S., based on the population distribution shown in the table, is:
There was overseas migration from Europe and Asia to U.S. port towns.
The data indicates a significant increase in urban population percentages, which aligns with the historical context of increased immigration during this time period, as people from Europe and Asia moved to the U.S. seeking economic opportunities, particularly in urban areas associated with industrial growth.
