The numbers look like they might be correct.
The WOL poster interestingly enough left out reporting any of the disService Year 2000 figures that were higher than the corresponding 2001 figures.
Baptisms: 2000: 288,907 (left out of WOL report)
Baptisms: 2001: 263,431 (decline of 25,476 or 8.81 percent)
Also of note: the average congregation size, already small, is getting smaller.
Congregation size: 2000: 65.97182
Congregation size: 2001: 65.67261
