Cross posting from another thread. It seems that I might not be the only nerd here that's interested in statistics like this so maybe it deserves it's own topic.
So I was playing around with google.com/trends with some JW related search terms. I found the results a bit surprising, and certainly interesting, so I figured I'd share.
First off, the link to what I tried.
One of the most surprising things that stood out was the regional interest. The top 3 countries for both "jw.org" and "Jehovah's witnesses" searches are Angola, Zambia and Congo, and the entire top 10 of both lists is dominated entirely by the 3rd world. Now, I think google scales these based on the total search volume from the regions in question, so it's perhaps a little less shocking, but it does show that the per capita interest in JWism is much higher in 3rd world countries than it is in the more educated/secular places. On a scale from 1 to 100 the US ranks a 6 for interest in JWs, and the UK comes in at 3. Pretty dismal, I'd say.
Another thing that I found interesting was the related searches section. The top 2 related searches for jw.org (once you skip the obvious "jw") are both clearly made by spanish speakers (and jw.org/es - the spanish site - also made the top 10). Also, several of the top 10 related searches for "Jehovah's Wittness" are clearly not english. It seems that the bulk of the interest in JWism is from latin america(since spain is significantly more secular than latin america, i think we can assume spaniards are contributing very little to the spanish JW related searches) or from immigrants originating in latin america. This supports what I've seen in the US, where it seems the only congregations that are growing are foreign language groups, and especially the spanish congregations (though they seem to be plateauing).
The JW.org campaign of august does seem to have had a little success with a peak in interest in august. However, I suspect the roughly 50% increase from July to August was less than what the typical R/F JW would expect. Where was that success, though? Not in the US or UK! If you filter by region, interest in JW.org peaked in January of 2013 in the US and October of 2013 (the app/bible release) in the UK.
I think by itself this is essentially irrefutable evidence that the JWs are experiencing decline in the US, UK and western europe.
