The national debt is about 11 trillion dollars [source U.S. Treasury].
There are about 300,000,000 people in the U.S. Therefore the national debt per person is about $36,000. [or about $108,000 per family of three].
The $116,000 figure differs slightly, but is certainly a lot more than $16,000 per person [or $48,000 per family of three] which is still terrible.
