Based on the 2009 and 2010 Yearbooks:
2008 Avg. Publishers: 6,691,790
2009 Avg. Publishers 6,829,455
Increase 2008-2009: 137,665
Baptisms 2008-9: 276,233, or about 5312/wk.
"Missing" Publishers: 138,568, or about 2665/wk.
In other words, over half the number baptized stopped "publishing" in the 2008-9 service year (not necessarily the same individuals, of course). We might attribute a small percentage of this decrease to deaths, but that would be almost insignificant in view of the obviously large numbers leaving the organization.
