I read today that US has a national debt of $7 trillion. I wonder who to. I found a table of NZ national debt through history which appears to show that current NZ debt is approximately $6.5 billion. NZ’s population is approximately 4 million. The US’s population is about 292 million. So US debt per person is about USD24,000, and NZ debt per person is around NZD1,600. Feel so free to check my working.
