Stats very interesting

What do New Hampshire and Iowa have in common? If you answered “first in the nation” status, you are correct. But I’m not talking about the presidential campaign process. Instead, I’m referring to the world-wide rankings of geocaching regions.

One of my fellow reviewers who goes by the user name Riviouveur and who reviews caches for France, likes to collect geocache statistics. He graciously consented to let me publish some of the data he collected from the www.geocaching.com site.

One stat that I find especially interesting is that, for the period from May 30, 2007 to January 27, 2008, of all the states in the U.S., only New Hampshire had a greater percentage increase in its number of geocaches (42.8%) than Iowa (42.2%). During those eight months, Iowa went from having 2,943 geocaches to 4,184 – an increase of 1,241 caches. That equates to approximately 155 new caches per month since last May.

According to Riviouver’s calculations, Iowa now has 28.7 caches per 1,000 square kilometers, which equates to roughly .011 per geocaches per square mile (if my math is correct). That puts us 51st out of 143 regions (countries and states) worldwide in terms of cache density. So Iowa is not a cache-barren land. In fact, we’re closer to the top of the list than the bottom.

In terms of population, we currently have 140.4 caches per 100,000 population, which ranks us 28th on the list of 143 worldwide regions. That means Iowans like to hide geocaches more than average.

Another factoid, the numbers included in the spreadsheet are ACTIVE cache figures. Reviewers have actually reviewed more caches than those numbers indicate. The numbers that appear here are the net of total caches submitted minus those that have been archived and minus those that were not approved for listing.

Some additional trivia from Riviouver:
- Five US states hit 10,000 active caches in the last two months.
- The numbers are growing substantially faster outside the U.S. than within the U.S.
