The following information was compiled from the best information that we have available. However, opinions vary from source to source, and occasionally new information becomes available. The estimates of world populations, in particular, are in some cases a little more than educated guesses.

If you have more recent or accurate information please let us know. We are always looking for opportunities to improve the information presented in these pages. If we use information that you provide, we will add your name as a contributor at the end of the applicable section. Please feel free to e-mail questions & comments to George Stowers at: gstowers@mint.net
