Final answer:
Immigration patterns in the U.S. changed from Northern and Western European to Southern and Eastern European origins over the 19th century, due to economics, politics, and policy changes. Urban growth was driven by the development of transportation, and the American Dream was a key factor in the economic success and cultural influence of the United States.
Step-by-step explanation:
Patterns of Immigration and Migration in U.S. History
The region or country of origin for immigrants to the United States has varied greatly over different eras. Initially, most immigrants came from Northern and Western Europe, especially in the early 19th century. Later, towards the end of the 19th century, this shifted to Southern and Eastern Europe. Factors that explain these changing patterns include changing economic opportunities, political situations abroad, shifts in U.S. immigration policy, and the opening of new lands for settlement.
Economic and Urban Growth
The development of new forms of transportation significantly influenced urban growth, enabling cities to expand and accommodate more residents, thereby changing the American landscape. The American Dream contributed to the United States becoming the world's largest economy by promoting the values of hard work and prosperity, which fostered economic expansion and innovation. Additionally, this concept has been exported globally, influencing other nations and contributing to the spread of American culture.
