To summarize modern human migration patterns effectively, it's necessary to consider broader trends rather than focusing on a single statistic, especially one specific to the United States. Modern human migration is influenced by a variety of factors, including economic opportunities, conflicts, environmental changes, and social networks.
A better summarizing statement about modern human migration would highlight the increasing mobility of populations globally, the rise of urbanization, and the influence of globalization. For example, you could say:
"Modern human migration is characterized by increased global mobility, with millions of people moving across borders for economic opportunities, escaping conflict and persecution, and seeking better living conditions, resulting in diverse multicultural societies in urban areas."
This captures the essence of current migration trends, emphasizing the complexity and multi-dimensional nature of human movement today.
