Jan,
The numbers are pulled directly from the Jehovah's Witnesses publications. In the past they would use the dropping number of memorial partakers as "proof" that the end was near. Now from their own publications it has raised to 14,000 from what the average number was of around 8,500 for decades. The official line is NO LONGER the numbers are falling. If anything they allude that the massive increase may be from people who are not really anointed but just think they are. Either way they say to leave it in Gods hands. To verify the current number of partakers you can download the 2015 yearbook from the JW website and go to page 176 under Grand Totals. Here is a link you should check out that explains it very clearly what has happened along with where you can find the material in the Jehovah's Witnesses literature. http://www.jwfacts.com/watchtower/memorial-partakers.php
