Statistical puzzles

Some people live on a diet of statistics, others just choke on them - I quite enjoy them as an occasional 'meal out' when I want to think a few different thoughts. Thanks to a friend who eats only trends, varriables and mediums, I recently came across quite an interesting set of numbers. (Thanks Peter - after all someone has to digest those numbers!)

Apparently there are only two religious groups in the world projected to grow in the next 40 years - Evangelical Christians and Muslims. The figures are:

1970 to 2050 Evangelicals From 7% to 15% of world population

1970 to 2050 Muslims From 15% to 25% of world population

As a total Christians are currently the largest religious group in the world, at 33%, and if all Christians groups were to grow at the same rate as Evangelicals then this would remain the case - but the fact is that non-Evangelical Christian communities are just not growing (with a few notable exceptions such as certain Orthodox groups). You see this more starkly when you view Evangelicals as a proportin of the Christian community. The figures are:

1970 to 2050 Evangelicals From 14% to 46% of Christians in Developing World

1970 to 2050 Evangelicals From 25% to 47% of Christians in Developed World

1970 to 2050 Evangelicals From 21% to 46% of World Christians

So? Well perhaps Evangelicals need to help their non-Evangelical sisters and brothers to grow. Not to become Evangelicals, but to be confident in their own faith and to GROW.
