To evaluate the cause of increased migration to the U.S. based on population distribution, the most relevant statement would likely be:
There was overseas migration from Europe and Asia to U.S. port towns.
This statement accurately reflects a historical trend, especially during the late 19th and early 20th centuries when large numbers of immigrants from Europe and Asia moved to the United States, often arriving at port towns on the East Coast. This influx contributed significantly to the population growth in urban areas.
The other statements either pertain to internal migration within the U.S. or inaccurately describe the economic conditions created by the Industrial Revolution. For example, the Industrial Revolution primarily created more jobs in urban areas as factories and industries developed, not in rural areas.
