One of my favourite graphs regards the declining conversion rate.
This must be what concerns the Governing Body most. This has dropped dramatically, with the Annual Number Baptised compared to Average Monthly Studies falling from a high of around 1 in 5 (22%) prior to 1975, to now a mere 1 in 33 (3%). During the 1980's and 1990's the conversion rate was consistently around 8%. This has steadily declined to less than 3% in 2014. (Please note that this is a comparative rate, not an exact one, as it is based on "average monthly Bible studies", and some Bible Studies may extend for years, whilst others for less than one year.)
Whilst the number of baptisms rises with the number of publishers, the number getting baptised each year is actually less than its peak in the 1990s.
