I tried posting a link to the United States Department of Agriculture report on honey production/prices by state with estimates of numbers of producing colonies. I'm not really sure how accurate it is, but it is probably the best we have for the U.S. and it should answer a number of your questions. Because I have not posted enough, I am not able to put in the actual link. If you do a google search for "USDA honey report for 2012" or something like that, you should be able to pull up a link to the 2012 report.
