In the first half of the twentieth century, most immigrants came to the US from European countries. Between 1950 and 2000, the pattern of immigration to the US underwent significant changes:
1. Most immigrants came to the US from Latin America: A large number of immigrants came from countries in Latin America such as Mexico, Cuba, and various countries in Central and South America.
2. Some immigrants came to the US from the Middle East: Immigration from countries in the Middle East increased during this period, with people coming from regions like Iran, Iraq, and Syria.
3. Few immigrants came to the US from Oceania: Unlike the significant influx from European countries in the early twentieth century, the number of immigrants from Oceania (Australia and surrounding islands) remained relatively low compared to other regions like Latin America and the Middle East.
These changes in immigration patterns reflect geopolitical events, economic opportunities, and other factors that influenced where immigrants came from during this period.
