The facts: Urban areas of 1 million+
The map below shows the most reached and unreached cities in the world: cities with more than 20,000 Adventist church members living in them are in green; those cities with fewer than 125 church members are in red (125 is the average size of an Adventist congregation, so red shows cities without the equivalent of an Adventist congregation in them). What this reveals is that almost all big cities with a strong Adventist presence are in the Americas and sub-Saharan Africa, with just a few in Asia. The big cities with the weakest Adventist presence are all in the 10/40 window—and in Europe.
