Gold is working its way up the ranks

Behold world metal production for the past five years, expressed in dollars per capita. For now, I am only offering minimal comment.

Data for production and values from the USGS commodity reports; population data eyeballed off a chart. I used reported annual average prices rather than closing prices.

It's ferrochrome's world--the rest of the metals just live in it.


  1. Two questions:
    1 Is chromium the #1 commodity in metals?
    2 Can you also put nickel in the chart?

  2. I also have a little trouble believing the chromium numbers.

    I am planning a follow-up with the second-tier metals (lead, zinc, nickel, silver). They couldn't go on this chart (unless I went logarithmic) as they are all at about the $1 level.
