My understand is in general in the United States it's not enough of an issue to require you to buy iodized salt. https://www.nytimes.com/2017/07/21/well/eat/sh

  But that's statistically speaking - GP seems to be enough outside the norm to spend a few minutes thinking about this. The question I'd ask is whether American soils used for farming are generally enough iodine-rich, or whether the problem rather goes away by people eating lots of processed foods containing iodized salts.
