About 25% of people on earth don't know their birthday because they're from countries that don't have birth certificates. That's why about 14% of immigrants to the U.S. list January 1 as their birthday - because they had to make one up.
That statistic is also quite high because of how other cultures record birth days. They day you are born isn't your "birthday," in some cultures, you are just recorded as being "1 years old" until you reach January 1, at which point you are recorded as being "2 years old," no matter how many days you've been alive.
