Overview: The greatest challenge for world evangelization is presented probably by the peoples of the South Asian affinity bloc. It has more unevangelized individuals and people groups than any other region of the world, and yet in some segments of its societies the Church is growing vigorously. Its ethnic, linguistic, religious and social complexity defies easy description. Overshadowing all is the pervasive caste system that blights India and Nepal especially. The people clusters that comprise South Asian Peoples are based mainly on ethnic origin, language and (to an extent) religion. It is helpful to see the sub-continent in this way, but a three-dimensional model that also incorporates caste is needed.
