[@A Tattooed Girl] 97. If you ask because of that whole thing that I didn't get my letter because Voldemort wiped out all the Ministry's records of muggle-born wizards and witches born from 1985-1998 I am 99.9 percent sure that doesn't apply to American muggle borns. After all they do have Ilvermorny here and as it says above, he wiped all Ministry of Magic records not MACUSA (Magical Congress of the United States of America) records. 

If that isn't why you are asking then I am curious as to why you are.
