America Is Flint
If I understood the article, what Kristof is saying, is that as bad as Flint appears to be for children, there are a lot of places as bad, or worse, that are getting no press at all.Testing for elevated level of lead in children:   o Flint - 4.9% 
   o New York State (outside of NYC): 6.7%
   o Pennsylvania: 8.5%
   o Westside Detroit: 20%
   o Iowa: 32%

If these figures are true (and one hopes that the NYT fact checked these numbers), and are comparable, it seems like what's happening in Flint is just the tip of the iceberg.
