Wow, those numbers are astonishingly appalling! 
Global statistics: 6,390,022 (2005 avg pub) + 248,327 baptisms = 6,638,349 (projected total for 2006)...
However.....
6,638,349 (projected total for 2006) - 6,491,775 (actual 2006 avg pub) = 146,574 publishers unaccounted for = 2.2% AWOL
[edited due to calculator failure 
that's my story and I'm sticking to it!]
In Canada, the increase was 84 Publishers™ from 2005 to 2006, despite the fact that there were 1982 baptisms. Where have the other 1898 (1.8%) Publishers™ gone?
In terms of hours spent preaching: Canada's 19,060,967 hours in 2006, divided by 12 = 1,588,413.9 average hours per month total; 1,588,414 hours divided by 107,618 average Publishers™ per month = 14.76 hours per month
Factor in Pioneer™ hours at a minimum of 70 hours per month required and Auxiliary Pioneer™ hours at a minimum of 50 hours per month required:
7655 Pioneers™ x 70 hours per month x 12 months = 6,430,200 hours total
4068 Auxiliary Pioneers x 50 hours per month x 12 months = 2,440,800 hours
19,060,967 total hours - 6,430,200 Pioneer™ hours - 2,440,800 Auxiliary Pioneer™ Hours = 10,198,967 Publisher™ Hours
10,198,967 Publisher™ Hours divided by (107,618 av Publishers™ - 7655 avg Pioneers™ - 4068 avg Auxiliary Pioneers™) = annual Publisher™ (only) hours
10,198,967 annual hours divided by 95,895 Publishers™ = 106.35 annual hours per Publisher™ (8.8 hours per month)
If the number of Publishers™ does not include Pioneers™ and Auxiliary Pioneers™, the average hours is even lower:
10,198,967 Publisher™ hours divided by 107,618 av Publishers™ = 94.8 annual hours per Publisher™ (7.8 hours per month)
This means that the average JW Publisher goes in Field Service™ less than 2 hours per week. This average would include a 1 hour per week Family Study™ (which most JW husbands count but seldom do in my experience).
That's a very, very bleak picture for Canadian JWs.
