The current US national debt stands at about $20.4 trillion, or roughly [tex]2.04\times10^{13}[/tex] dollars. For comparison, the US population is currently around 323 million people, or [tex]3.23 \times 10^{8}[/tex] people.
To find the amount of that debt each citizen shoulders, we can divide the two:
[tex] \frac{2.04\times10^{13}}{3.23\times10^{8}} \\\\ = \frac{2.04}{3.23}\times 10^{5}[/tex]
Dividing 2.04 by 3.23 gets us approximately 0.632, so the total debt of each citizen would be about
[tex]0.632\times10^{5}=0.632\times100,000=6320[/tex]
So, the US has a per capita federal debt of roughly $63200
