This is the report based on a survey that I took part in (at least I think I remembered to fill it in and send it off) and it's about men and full-time pastoral ministry in the UK. There are other related items on this website.
And while we're on the subject of statistics and issues of growth and decline in the UK Church, 'Christian Research' have some excellent information on their t'internet site, including some details from the 2005 English Church survey.
To me, the most alarming statistic from the 2005 survey is that now only 6.3% of the population attends Church (just over 3 million people). There is some good news as well in the report (decline is slowing down, about a third of churches are now growing) but 6.3% is very low indeed. Especially when you consider that the 6.3% is not made up entirely of gospel people or gospel churches.
All of which is a good reminder of why someone would go to bible college in the first place. By the grace of God we'll see these statistics turn around to the glory of God in Christ.
