Which regions have primarily composed the migration streams into the United States since 1980?

Since 1980, the predominant migration streams into the United States have primarily come from Asia and Latin America. This pattern reflects significant global changes, including economic opportunities, social connections, and shifting immigration laws that have facilitated a surge in migrants from these regions.

The increase in immigration from these areas can be attributed to factors such as conflicts, economic instability, and the search for better employment and education opportunities. For instance, many Latin American countries have faced political and economic challenges, prompting individuals and families to seek refuge and a better quality of life in the U.S. Similarly, countries in Asia, such as India, China, and the Philippines, have seen a significant number of emigrants due to India's growing tech industry, China's expanding middle class, and other drivers of migration.

The data supports that these two regions have been responsible for a majority of immigration to the United States, highlighting their critical role in shaping the social, cultural, and economic landscape of the nation in recent decades. In contrast, other regions listed, such as Europe and Africa, have seen a decrease in the percentage of migrants, whereas Oceania and South America contribute less significantly to overall immigration trends in the U.S. during this timeframe.
