I snagged this off of a friend's blog...

Interestingly enough:
# There are 1,415,947 people in the U.S. with the first name Jennifer.
# Statistically the 21st most popular first name.
# More than 99.9 percent of people with the first name Jennifer are female.


While this is an interesting little widget.. I'm not sure I trust the data.. I entered my sister's last name (married name) and it showed that there was no one in the U.S. with that name.. and I happen to have met a dozen or so of them... weird.
