Just out from the Pew Forum:
Global Survey of Evangelical Protestant Leaders (pdf:
link)
Cliffs: ~2k evangelical leaders from around the world surveyed...lots of statistics, mostly comparisons between Evangelical Christianity in the "Global North" (Europe, North America, Japan, Australia and New Zealand) and the "Global South" (sub-Saharan Africa, the Middle East and North Africa, Latin America and most of Asia). Seems evangelicalism is booming in the South, busting in the North.
