The New York Times issued a Jan. 22 correction to its Jan. 15 opinion article that incorrectly reported in its subheadline that 46 million U.S. people are on prescription drug Xanax.

Forty-six million people on Xanax in the U.S. would indeed be a stunning number, as that would be about 15% of the U.S. population.  According to July 2009 statistics from the U.S. Census Bureau, there are 307 million  people in the U.S.
