1) Where does the NCC obtain their information? The link states: Ranked 20th in size, the Jehovah’s Witnesses denomination reported a 4.37 percent gain in membership, with 1,162,686 members total. So the WT reports the growth rate which is not verified by the NCC?
2) Is the same growth calculation criteria used throughout all reporting denominations?
3) What does the WT use as an indicator of growth? Baptisms, Field Service reports (15 minutes reported once every three months), number of seats filled on average, number of seats filled at the memorial?
4) Are walk-aways, DF'd, DA'd, deaths subtracted from the growth figures?
5) Are the figures accurate or are they doctored to bring prominence to the report?
It's interesting that JWs were included within the groups named following this statement: But a few church bodies, regarded as cults by some Christians, continue to increase in size.
