Annoying that they seem to be holding back the average figures for some reason.
I reckon we'll see fewer and fewer statistics released in coming years. This is just the start. In fact it's not the start. It's part of a long trend going back at least to when they ceased publishing the monthly figures in the Kingdom Ministry.
I see Russia has been removed from the listing and added to the "other" column. Which produces an overall decrease. Comparison of this table with yours should reveal exactly how many Russian JWs have been lost in the last year.
I make that out to be 165,594, down 6,234 (3.6%) from 171,828. Not that big a decrease, considering the ban.
