When considering global religions, countries are usually conceptualised in terms of the religion which holds most sway - Buddhism in Thailand, Islam in Indonesia or Christianity in the USA. But this perspective obscures the part that other religions might be playing in those countries. The map below, which divides the world's nations according to second-largest religions, provides an unexpected perspective, particularly on "Muslim" regions of the world.
What this map doesn't make clear: many nations, especially in Asia, wouldn't register Christianity even on a map showing fourth or fifth largest religions. Also: in most of the nations coloured blue for Christianity on this map Christians still represent less than ten percent of the population.
