To add...
Also consider that many/most JWs have children these days. This was not the case before the mid-1990s. The 1-2% growth that is reported is roughly consistent with population growth. No converts here.
Most converts are in underdeveloped countries, (at least where things such as sharia law do not exist), or those with severe social issues.
Any increase in numbers in developed countries is based on the fudging above, children being born and "publishing", and immigrant migration.
