Why is zip code data on an environmental science site?
In 2002 I was working on a project that correlated pollution and income for postal codes across the United States and Canada. While the Canadian effort did not work out so well, visitors told me the data files were very useful so I left them on the site and now update the postal information on a periodic basis even though the focus of the site is conservation.
