Answer:
Twice as many people were from Europe in 1900 than in 1990.
The European-born population increased between 1900 and 1930.
The European-born population decreased between 1930 and 1990.
The European-born population decreased between 1900 and 1990.
Step-by-step explanation:
Twice as many people were from Europe in 1900 than in 1990.
-This is so because in 1900 some 8,881,548 entered America, that is, more than double that of the 4,350,403 who entered in 1990.
The European-born population increased between 1900 and 1930.
-In fact, the European population that entered America went from 8,881,548 in 1900 to 11,784,010 thirty years later.
The European-born population decreased between 1930 and 1990.
-Between 1930 and 1990, there was a notable drop in the entry of Europeans to the United States, from more than 11 million in 1930 to more than 4 million in 1990.
The European-born population decreased between 1900 and 1990.
-The same happened between 1900, when almost 9 million Europeans entered, and 1990, when less than half of that number entered.
