With data from the USDA on certified organic farms for 2008. I created a map using the Geo Map function from the googleVis API package available in R. I’ve copied and pasted the image below as WordPress.com sites don’t support scripting so the rollover functionality is, unfortunately, lost. But because this is really the easiest way to create a choropleth map i went with it and did some of my own editing. Maine and Vermont top the list of the highest proportion of certified organic farming and livestock operations with a huge total of 8% each with California coming in a distant second at 4%. The fewest such operations as a fraction of the total number of farms is found in across the South with Mississippi, Arkansas, Louisiana, Tennessee, West Virginia and Alabama all below .06%.
